The concept of region or regional geography

1) What is meant by region? Explain the importance of regions in the study of geography.

Answer: In the general sense, a region refers to the presence of an area of the Earth's surface ǀ but in geography the term region has a different definition ǀ it describes the natural, social, political or economic condition of an area ofthe Earth's surface             Our world is diverse. Every region or every place has its own existence and characteristics. There are also differences in environment. The natural environment varies from place to place on the Earth's surface due to many factors such as the Earth's position in the Solar System, its own shape, structure, and rotation. The status and properties of resources vary in different natural environments. The economic development based on it will naturally be different. There are also differences in social background, customs, language, dress, eating habits, etc. from one environment to another. The inclusion of regions in the study of geography therefore provides a glimpse of much knowledge in this direction ǀ

2) Explain how areas can be identified on the surface ǀ

Answer: Different regions of the world reflect their own geographical, social, political or economic ǀ so to get an overall overview it is necessary to divide the big world into smaller parts. Only then will it be possible to determine the true nature of each part. Geographers divide the Earth's surface for the convenience of study for specific purposes. Such classification is usually done in two ways: (1) on the basis of similarity of geographical components and (2) on the basis of functional relationships of components. A part identified on the basis of similarity is called a homologous region and a part identified on the basis of functional relationship is called a functional region. Homogeneous areas Natural areas are identified based on the similarity of natural components such as soil, climate, plants etc. For example, the Brahmaputra Valley of Assam can be considered as a small natural region ǀsuch regions are defined based on the functional relationships between components. Functional areas are usually identified around the city or market. For example, the areas around a city are interconnected with the city in such a way that the surrounding area is interconnected with the city. For example, the city of Guwahati in Assam has a large functional area.

3. Distinguish between homologous regions and functional regions ǀ

Answer: co-religious regions =

1) Symbiotic areas Natural areas are identified based on the similarity of natural components such as soil, climate, vegetation etc.

2.&nbsp;Certain components are selected and co-region is identified ǀ

3.&nbsp;Different components belonging to homogeneous regions may not be dependent on each other ǀ

active region =

1) Such zones are defined based on the functional relationship between the components. Functional zones are usually identified around the city or market centre.

2.&nbsp;Functional zones are defined based on socio-economic and communication status ǀ

3.&nbsp;The different components belonging to the functional area are interdependent ǀ

4. What is the regional geography of the world? What is the significance of such a study?

Answer: Regional geography presents the overall geographical picture of a region, country or continent of the world ǀ it details the natural, social, economic and transportation conditions within a country or region ǀ regional geography also gives an overview of spatial differences within the region ǀ presents the relationship or difference between the region in question and the region in question             Regional geography can be a good study of a region. Studying several regions simultaneously reveals which region is ahead and which is lagging behind. Regional geographical studies can also determine why an area is lagging behind. Thus, regional geography can help in regional development planning. Therefore, what is a region, how it can be defined, how regional development can be made possible, are related to the subject of geography, especially regional geography

5) What is meant by 'natural zone'? How many natural zones can the whole world be divided into? Name each and show them on the map ǀ

The major natural regions of the world are:

(1) Equatorial regions

(2)&nbsp;Monsoon regions

(3)&nbsp;Tropical grassland region

(4)&nbsp;Tropical hot desert regions

(5)&nbsp;The Mediterranean region

(6)&nbsp;Mid-latitude desert regions

(7)&nbsp;Mid-latitude temperate zone.

(8)&nbsp;Mid-latitude grassland region

(9)&nbsp;Cold simple forest areas

(10)&nbsp;Cold polar regions

(11)&nbsp;High mountainous areas&nbsp;

6. How can knowledge of the regional geography of the Earth be gained through the study of natural areas? Write briefly.

Answer: Natural areas are those parts of the Earth's surface that have almost the same topography, climate, natural vegetation and soil properties. Some of these characteristics of the natural environment distinguish one region from another. There is no significant difference in the natural environment and human lifestyle between the places within such a natural area. Similarly, regional differences in natural and socio-economic conditions are also evident within a continent, country or state. Therefore, to know the overall state of a continent, country or state, one must carefully study every component of its natural and human environment and the relationships between them. Therefore, the study of natural regions is important ǀ Regional studies provide knowledge about the environment of a country or region as well as socio-economic development and related problems.

7. Write about the geographical environment of each natural region of the world ǀ Answer:

1. Equatorial Zone -&nbsp;The equatorial zone is located between 10° north and 10° south latitudes on both sides of the equator. The climate of this region is warm and humid. The sun's rays fall almost vertically in this region and there is little difference in temperature between day and night and between summer and winter. The average annual temperature is 27°C. The average annual rainfall in this equatorial region is 200 cm. The Amazon River Basin in South America, the Congo River Basin in Africa (now the Zaire Basin), the Guinea Coast in West Africa, and the Malaysian Peninsula in Southeast Asia, and the Indonesian and Philippine Islands belong to the equatorial region.

2. Monsoon Zone-&nbsp;The monsoon zone generally extends from 10° to 30° north latitude to the north of the equatorial region and from 10° to 30° south latitude to the south. In fact, the areas affected by the monsoon winds belong to this region. The main characteristic of the climate of the monsoon region is the change of seasons—hot and humid summers and cold. and dry winters. The temperature difference between summer and winter is 15°C. The average annual rainfall is 200 cm. The monsoon zone extends to tropical and subtropical latitudes. It belongs to the monsoon natural regions of South Asia including India, Southeast Asia, northeastern Australia, eastern Africa, eastern Brazil, Central America, etc.&nbsp;

3. Mediterranean Region -&nbsp;The Mediterranean climate is generally found in the western margins of the continent in midlatitudes and especially in the northern part of the tropical deserts. This | The natural region is characterized by hot and dry summers and cold and dry winters. This means that the region receives rainfall only in winter. Summer here is somewhat long. The average temperature throughout the year is 8-25°C. The annual rainfall is 25-75 cm.&nbsp; These natural conditions are usually found in the areas along the Mediterranean Sea. The region consists of southern Europe, southwestern Asia and northern Africa along the Mediterranean Sea&nbsp;

4. Cold Simple Forests –&nbsp;Cold Simple Forests are located between 50-70° latitude in the Northern Hemisphere. It is bordered by the tundra region to the north and the mid-latitude grassland region to the south. This is. The climate of the region is somewhat dry and cold. In summer, temperatures rise to an average of 15 degrees Celsius. In winter, snow falls due to lower temperatures. Summer is shorter than winter in this region. There is some rainfall in summer.&nbsp; The region extends from Scandinavia in Europe to the Pacific coast in the east and from Alaska in North America to the Atlantic coast in the east. It covers a large area of Europe, Asia and North America.

5. Mid-latitude temperate zones –&nbsp;Temperate natural zones in many parts of mid-latitudes in both hemispheres of the Earth. existing. These natural areas are generally found in many places in the northern hemisphere from the equinox of Cancer (23° north) to 50° north latitude and in parts of the southern hemisphere from the equinox of Capricorn (23 south) to 50° south latitude. There is little incidence of cold poisoning in this area. Summer temperatures average 15°C and winters 5-10°C. The climate of the coastal areas is temperate. The average annual rainfall is between 75-150 cm. Rainfall decreases with distance from the sea. Winters in this area are very dry.&nbsp;

6. Tropical Grasslands-&nbsp;Tropical grasslands are usually found at the end of continents in the tropical zone ǀ extending to 10°—25° north and south latitudes in South America, Africa and Australia. Such grasslands have a special natural condition between equatorial and tropical desert regions. The climate of the tropical steppe region is characterized by warm and short summers and dry and long winters. Daily and seasonal temperature variations are high in this region. The rainfall during the year is moderate (25—100 cm). The Oriniko River Basin in South America, located in the Brazilian Highlands and Venezuela, the northern and southern parts of the Zaire Basin in Africa, the East African Highlands and parts of South Africa, and the northern part of Australia belong to the Tropical Grassland Region.

7. High mountainous areas –&nbsp;As the altitude increases, a special natural condition prevails in the mountainous areas. The Himalayas in Asia, the Alps in Europe, the Rocky Mountains in North America and the Andes in South America cover vast areas. The temperature decreases noticeably with increasing altitude. For example, its peaks in the Andes Mountains are always covered with snow. The northernmost and southernmost parts of the Earth covered with snow throughout the year are called the polar regions. ǀIn the Northern Hemisphere, this region is usually located north of the Arctic Circle. In winter, the temperature drops to -18°C. There is almost no rain here. In winter there is rather plenty of snow. Because it is snow-covered most of the year, it includes the polar regions of Asia in the Northern Hemisphere, Europe and North America, including Greenland, and Antarctica in the Southern Hemisphere.

8. Mid-Latitude Grasslands –&nbsp;Mid-Latitude Grasslands are located between 30°—50° Nari latitude in the Northern Hemisphere and south of the Capricorn Eclipse (231 ̊2 S) in the Southern Hemisphere. In fact, the interior of the continents has become a grassland due to low rainfall. The inland location has increased the temperature difference between summer and winter in the region. It receives some rainfall only in summer. The average annual rainfall is only 15–50 cm.&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;There is almost no vegetation in the area due to the cold weather.&nbsp; Central North America, eastern Europe, central Asia, Argentina, parts of South Africa and parts of Australia belong to this mid-latitude grassland region. The meadows located in this area are known by different names. Such grasslands are called steppes in Asia and Europe, prairies in North America, posh in Argentina in South America, veld in South Africa and daursh in Australia.

9. Cold Polar Region-&nbsp;The northernmost and southernmost parts of the Earth are covered with ice all year ǀIn the Northern Hemisphere, this region is usually located north of 661 ̊2 of the Arctic Circle. In winter, the temperature drops to -18°C. There is almost no rain here. In winter there is rather plenty of snow.&nbsp; This natural region of the North Pole is known as the Tundra region. This natural area includes the polar regions of Asia, Europe and North America in the northern hemisphere, including Greenland, and Antarctica in the southern hemisphere.

10. Tropical Hot Desert Regions –&nbsp;&nbsp;&nbsp;&nbsp;Tropical deserts are usually located at the western ends of continents ǀ these deserts extend to the vicinity of the Cancer Eclipse (2312 ̊ north) and the Capricorn Eclipse (2312 ̊ south). The climate in this region is almost always hot and dry. The difference between day and night temperatures is large.&nbsp; In summer, the daytime temperature rises to 45°C. The rainfall is very low. The average annual rainfall is 20-25 cm. Due to lack of rainfall, only short grasses and thorny plants grow in parts of such desert areas. Much of this area is covered with sand. However, the desert gardens scattered around the desert grow some date palms and are cultivated to an equal extent.

11. Middle latitude desert regions-Parts of the plateaus and basins at the end of Asia and North America are desert in nature. Such natural areas are surrounded by high mountains. It is located far from the sea and surrounded by high mountains and receives very little rainfall. Due to its continental location, the temperature difference between summer and winter is high. Similarly, the difference in temperature between day and night is also noteworthy. Winter is somewhat snowy in the region.

8. Discuss the climate and plants prevailing in different natural regions of the world&nbsp;

Answer:

a) Equatorial Zone:&nbsp;The equatorial zone is located on both sides of Vishnu between 10° north and 10° south latitude. The climate of this region is warm and humid. The sun's rays fall almost vertically in this region and there is little difference in temperature between day and night and between summer and winter. The average annual temperature is 27°C. The average annual rainfall in this equatorial region is 200 cm.&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Almost the entire equatorial region is covered with evergreen dense forests. There are also numerous small shrubs and trees ǀ dense forests and the natural environment of the area is not suitable for human habitation due to extreme heat and rainfall throughout the year.&nbsp;

b) Monsoon Zone:&nbsp;The monsoon zone generally extends from 10° to 30° north latitude to the north of the equatorial region and from 10° to 30° south latitude to the south. In fact, the areas affected by the monsoon winds belong to this region. The main characteristic of the climate of the monsoon region is the change of seasons—hot and humid summers and cold and dry winters. The temperature difference between summer and winter is 15°C. The average annual rainfall is 200 cm. Rainfall varies with the change of seasons ǀ&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Deciduous plants are predominant in this area. In winter, these plants lose their leaves due to lack of rainfall.&nbsp;

c) Tropical Grasslands:&nbsp;Tropical grasslands are usually found at the end of continents in the tropical zone ǀ extending to 10°—25° north and south latitudes in South America, Africa and Australia. Such grasslands have a special natural environment between equatorial and tropical desert regions. The climate of the tropical steppe region is characterized by warm and short summers and dry and long winters. There is a high daily and seasonal temperature variation in this region. The rainfall during the year is moderate (25—100 cm).&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Due to the tropical climate, herbaceous plants up to 3 m tall form extensive grasslands in the area. Such grasslands in the tropics are known as savannahs. The&nbsp;grasslands of Venezuela and Brazil are locally known as Lanos and Campos, respectively.

d) Tropical Hot Deserts:&nbsp;Tropical deserts are usually located at the western ends of continents ǀ these deserts extend to the vicinity of the Cancer Eclipse (2312 ̊ north) and the Capricorn Eclipse (2312 ̊ south). The climate in this region is almost always hot and dry. The difference between day and night temperatures is large.&nbsp; In summer, the daytime temperature rises to 45°C. The rainfall is very low. The average annual rainfall is 20-25 cm &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Due to lack of rainfall, only short grasses and thorny plants grow in parts of such desert areas. Much of this area is covered with sand. However, the desert gardens scattered around the desert grow some date palms and are cultivated to an equal extent.

e) Middle Latitude Deserts:&nbsp;Parts of the plateaus and basins of the end of Asia and North America are desert in nature. Such natural areas are surrounded by high mountains. It is located far from the sea and surrounded by high mountains and receives very little rainfall. Due to its continental location, the temperature difference between summer and winter is high. Similarly, the difference in temperature between day and night is also noteworthy. Winter is somewhat snowy in the region.

f) Temperate regions of middle latitudes:&nbsp;Many parts of middle latitudes in both hemispheres of the Earth have temperate natural regions. These natural areas are generally found in many places in the northern hemisphere from the equinox of Cancer (231 ̊2 north) to 50° north latitude and in parts of the southern hemisphere from the equinox of Capricorn (231 ̊2 south) to 50° south latitude. There is little incidence of cold poisoning in this area. Summer temperatures average 15°C and winters 5-10°C. The climate of the coastal areas is temperate. The average annual rainfall is between 75-150 cm. Rainfall decreases with increasing distance from the sea. They get. Winters in this area are very dry. according to the variation in precipitation.&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;There are many types of natural vegetation in this area. However, deciduous plants are found in most places. On the other hand, evergreens are dominant in areas with slightly higher rainfall and simple vegetation is dominant in areas along the mountains. Its forests are very thick ǀ

g) Mid-latitude grasslands:&nbsp;Mid-latitude grasslands are located between 30°—50° Nari latitude in the northern hemisphere and south of the Capricorn eclipse (231 ̊2 south) in the southern hemisphere. In fact, the low rainfall at the end of the continents has turned these areas into grasslands. The inland location has increased the temperature difference between summer and winter in the region. It receives some rainfall only in summer. The average annual rainfall is only 15–50 cm.&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;There is almost no vegetation in the area due to the cold weather.&nbsp; Central North America, eastern Europe, central Asia, Argentina, parts of South Africa and parts of Australia belong to this mid-latitude grassland region. The meadows located in this area are known by different names. Such grasslands are called steppes in Asia and Europe, prairies in North America, posh in Argentina in South America, veld in South Africa and daursh in Australia.

h) Cold Simple Forest Zone:&nbsp;Cold Simple Forest Zone extends between 50-70° latitude in the Northern Hemisphere. It is bordered by the tundra region to the north and the mid-latitude grassland region to the south. This is. The climate of the region is somewhat dry and cold. In summer, temperatures rise to an average of 15 degrees Celsius. In winter, snow falls due to lower temperatures. Summer is shorter than winter in this region. There is some rainfall in summer.&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Due to its cool and dry climate, the region is covered with evergreen forests. Softwood forest land filled with such simple trees is called taiga.&nbsp;

i) Cold Polar Region:&nbsp;The northernmost and southernmost parts of the Earth are covered with ice throughout the year. ǀIn the Northern Hemisphere, this region is usually located north of 661 ̊2 of the Arctic Circle It stays inside. In winter, the temperature drops to -18°C. There is almost no rain here. In winter there is rather plenty of snow.&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;No plants can grow in this area as it is covered with snow most of the year. With some warming in summer, grasses, algae and teak plants grow in areas where the snow begins to melt. This natural region of the North Pole is known as the Tundra region.

j) Mediterranean Region:&nbsp;The Mediterranean climate is generally prevalent in the western margins of the continent in midlatitudes and especially in the northern part of the tropical deserts. This | The natural region is characterized by hot and dry summers and cold and dry winters. This means that the region receives rainfall only in winter. Summer here is somewhat long. The average temperature throughout the year is 8-25°C. The annual rainfall is 25-75 cm.&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Evergreen short trees and shrub forests are the main natural vegetation of the area.

k) High mountainous areas:&nbsp;As the altitude increases, a special natural condition prevails in the mountainous areas. The Himalayas in Asia, the Alps in Europe, the Rocky Mountains in North America and the Andes in South America cover vast areas. The temperature decreases noticeably with increasing altitude. For example, although the southern Andes have equatorial forests, their higher peaks are always covered with snow.&nbsp; The climate and natural vegetation characteristics of mountainous areas also change depending on the wind direction. The southern slopes of the Himalayas receive heavy rains under the influence of monsoon winds, creating dense forests in this part. The northern part of the Himalayas, which faces the intense plateau, is almost devoid of vegetation due to lack of rainfall. Thus, different climates and natural vegetation can be seen within a very short distance due to changes in elevation and slope.&nbsp;

9. Give a description of the lifestyle of people living in different natural regions of the world ǀ Answer:

a) Equatorial zone:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;People have been farming permanently for centuries on the island of Java in Indonesia and in parts of the Philippines. After clearing the forest, the farmers cut trenches on the hillsides to carry out agriculture. They also grow a variety of crops in deep places. Paddy is the main crop of this region. On the other hand, much of Malaysia, Indonesia and Sri Lanka use plantation agriculture to produce rubber, tea and coffee ǀ much of the produce was exported to European countries, including Great Britain. Most of the Malay Peninsula is covered with rows of rubber trees.&nbsp; The entire region is economically developed through rubber cultivation as well as tea and coffee cultivation. The quality of life of the people has improved. Modern facilities have also increased.

b) Seasonal zones:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Agriculture is the main occupation of the people of the monsoon region.&nbsp; Agricultural production is high in the river valleys. The region is suitable for the production of various crops due to its hot and dry climate and seasonal changes. Apart from the main crop paddy, wheat, maize, cotton, cotton, oilseeds, tea etc. are grown in the region. The region is also rich in natural resources. The area is also densely populated. About 40 percent of the world's population lives in this monsoon region. The region has witnessed economic development with the development of science and technology.&nbsp;

c) Tropical grassland areas:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Tropical grasslands are very suitable for animal husbandry. Commercial cattle, horses, mosquitoes, sheep and goats are raised in most parts of the region. Such grassland areas are also home to wildlife. Therefore, many of the inhabitants of this area earn their living by raising animals and hunting. In addition, maize, sorghum, cotton, Chinese nut etc. are also grown to some extent in some places. This area is very sparsely populated. Most of the tropical grasslands are socially and economically backward due to poor transportation and lack of essential production facilities.

d) Tropical hot desert regions:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Most of the desert areas are uninhabited. Only some places are inhabited by nomadic herdsmen. The Bushmen of the Kalahari Desert and the Aborigines of Australia's Great Desert make a living by gathering food from nature and hunting wildlife. The Bedouins, who live in the Sahara and Arabian regions, earn their living by raising camels, horses, sheep, goats, etc. However, agriculture has developed through irrigation in the Nile Valley and delta regions. The area is permanently populated and densely populated. On the other hand, the occupations and economic conditions of the people of Kuwait, Saudi Arabia, Iran and Iraq, which are rich in petroleum resources despite being in the desert regions, are completely different.

e) Mediterranean Region:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Agriculture is the main occupation of the people of the Mediterranean region. The plains of this region are mainly cultivated with wheat, barley, maize, cotton, tobacco etc. depending on winter rains and irrigation. On the other hand, the hillsides are cultivated with a variety of fruits and vegetables, including grapes and apples. The people of this region are engaged in exporting various food items from the fruits and vegetables produced. A variety of wines are made from the abundant grapes produced. The region is world famous for its large-scale industry based on fruits and vegetables. Therefore, the whole region is economically advanced. The climate is mild and healthy and the population is dense.

f) Mid-latitude desert regions:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The mid-latitude desert regions are mainly inhabited by nomadic pastoralists, mainly in the Tibet and parts of the Patagonian Plateau and the Gobi Desert. These people have no permanent settlement as they move in search of fodder. However, irrigation has recently made some agriculture possible in the river valley areas. There has also been some economic improvement due to mineral exploration and industrialization. The entire area is sparsely populated. Some areas are relatively densely settled based on agriculture and industry.

g) Temperate regions of middle latitudes:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Most of the temperate natural regions are cultivated with improved methods. Intensive agriculture is practiced due to the dense population of northwestern Europe and northeastern China. Wheat and rice are grown extensively. The United States is sparsely populated and extensively agricultural.&nbsp; The east coast of South Africa is famous for its maize cultivation. In many parts of Western Europe, animal husbandry is practiced on a commercial basis as well as agriculture. In addition, the fishing industry has developed in coastal areas of China, Japan and Western Europe. The United States, Western Europe and parts of Japan are rich in mineral resources. Also, human resource development and transportation facilities have led the whole region in terms of industry ǀ&nbsp;

h) Middle latitude grassland areas:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Most of the people living in the grasslands of Central Asia are nomadic tribes. Their main occupation is animal husbandry. However, in the United States, Canada, Argentina, Australia and Russia, such grasslands are widely cultivated. Wheat is the main crop grown commercially in the region. Currently, these countries are the main exporters of wheat. Livestock is also raised commercially in grasslands in Australia, New Zealand and Argentina. The area has also developed a dairy industry based on domesticated cattle. Also the meat of cattle and sheep and goats, and the wool of sheep are produced and exported to various countries. Despite some economic progress, such grassland areas are still sparsely populated.

i) Cool simple forest areas:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The area is sparsely populated. The area is not suitable for agriculture and livestock breeding. Most of the inhabitants earn their living by hunting animals and collecting timber. European countries such as Norway, Finland and Sweden are famous for their wood pulp and the paper made from it. The discovery of minerals in Canada, Alaska and Siberia has led to the development of industrial centers in many parts of the region. This has resulted in the economic development of these places. Currently, some agriculture and sheep farming are practiced in the southern part of the taiga region.

j) Cold polar regions:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The extremely cold climate makes it very difficult to make a living in the tundra region. Permanent settlement is not possible here. The population density in this area is less than one per square kilometre. The tribals here live a kind of nomadic life. These people earn their living by hunting animals and collecting fish from the sea. The aborigines, who live in Alaska, northern Canada, and Greenland, are Eskimos and Lechs; Lashes and Fishes in Northern Europe and; and in Siberia known as Samwed and Yakut. In winter, the Eskimos live in ice igloos. In summer, however, they take strange shelters made of sealskins. Such is called a ‘ typical’. In the dry season, the Eskimos fish and hunt animals in boats made of animal skins called kayaks and umiaks. Dog-drawn sledges are the main means of transportation for these people.

k) High mountainous areas:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The lifestyle in the mountainous areas is very difficult and the population is sparse. Animal husbandry and timber trade are the main occupations of the people of this region. The river valleys are mainly used for agriculture. However, the inhabitants of the mountainous areas cultivate in a primitive manner. The tribal people have been doing such jhum cultivation in the agricultural areas for many centuries. Minerals have also been discovered in some parts of the mountainous regions. In addition, many places in the mountainous regions have developed as mountain residences and tourism centers due to their natural beauty and healthy environment. Darjeeling, Mussoorie, Nainital, Shimla, Shillong, etc. are some of the tourist destinations in India.

10. What are the other continents in the world? Give a brief geographical introduction to each continent

Answer:&nbsp;There are 7 major continents of the world ǀ they are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7)&nbsp;Antarctica

Asia:&nbsp;Asia is the largest continent in the world. It covers about 30 percent of the Earth's land area (44.4 million square kilometers). Asia is mainly located in the northern hemisphere. It extends from 1°N latitude in the south to 78°N latitude in the north and from 25°E longitude to 170°W longitude in the east. Broadly, the North Sea to the north of Asia; the Bering Strait and the Pacific Ocean to the east; the Indian Ocean to the south; and on the west by the Red Sea, the Suez Canal, the Mediterranean Sea, the Caucasus Mountains, and the Caspian Sea; The Ural River and the Ural Mountains. The continent is about 8,400 km north-south and about 9,600 km east-west. It has a coastline of about 58,000 km.

Africa:&nbsp;Africa is the second largest continent in the world. With an area of just over 30 million square kilometers, Africa covers about 20 percent of the Earth's land area. The equator, which runs almost through the continent, divides it into two parts. The continent of Africa lies between 37° North latitude in the north and 34° South latitude in the south, and 51° East longitude in the east and 17° West longitude in the west. It is bordered by the Mediterranean Sea to the north; the Southern Ocean to the south; the Indian Ocean to the east; and the Atlantic Ocean to the west. It has a coastline of about 30,000 km.&nbsp;

Europe:&nbsp;The continent of Europe is located on the northwestern border of Asia. It&nbsp;belongs entirely to the Northern Hemisphere. The continent extends from 36°N latitude in the south to 71°N latitude in the north and from 10°W longitude in the west to 65°E longitude in the east. It covers an area of 10.9 million square kilometers, or about 7.3 percent of the Earth's land area. Europe is bordered by Asia to the east, the Atlantic Ocean to the west, the North Sea to the north and the Mediterranean, Caspian and Black Seas to the south. Naturally, the Ural Mountains and the Ural River separate Europe from Asia. The continent of Europe is surrounded by oceans on three sides. Its mainland has a coastline of about 38,000 km.&nbsp;

North America:&nbsp;North America is the third largest continent in the world ǀcovering an area of24.3 million square kilometers, or 16.3 percent of the Earth's total land area. This continent of America is called North America because it is located in the northern hemisphere.

Answer:

a) Major grassland areas of the world:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The main grasses in the world are:&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1)&nbsp;Tropical Grassland Zone: This zone extends to 10°-25° north and south latitudes in Africa and Australia. The climate of the tropical steppe region is characterized by hot and short summers and dry and long winters.There is a high daily and seasonal temperature variation. The rainfall during the year is moderate (25—100 cm). Due to this climate, herbaceous plants up to 3 meters tall have formed extensive grasslands in the area. Such grasslands in the tropics are known as savannahs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2)&nbsp;Mid-latitude grasslands: Mid-latitude grasslands are located between 30°—50° Nari latitude in the Northern Hemisphere and south of the Capricorn Eclipse (231 ̊2 S) in the Southern Hemisphere. In fact, the low rainfall at the end of the continents has turned these areas into grasslands. There are few other trees due to the severe winters. There is almost no vegetation in this area due to the severe winters.&nbsp; Central North America, eastern Europe, central Asia, Argentina, parts of South Africa and parts of Australia belong to this mid-latitude grassland region. The meadows located in this area are known by different names. Such grasslands are called steppes in Asia and Europe, prairies in North America, posh in Argentina in South America, veld in South Africa and daursh in Australia.

(b) Equatorial natural areas:Vishnu is flanked by an equatorial zone between 10° north and 10° south latitudes. The climate of this region is warm and humid. The sun's rays fall almost vertically in this region and there is little difference in temperature between day and night and between summer and winter. The average annual temperature is 27°C. The average annual rainfall in this equatorial region is 200 cm.&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Almost the entire equatorial region is covered with evergreen dense forests. There are also numerous small shrub forests and thick forests of various kinds of creepers. The natural environment of the area is not suitable for human habitation due to extreme heat and rainfall throughout the year.&nbsp;

(c) Mediterranean Region:&nbsp;The Mediterranean climate is generally found in the western margins of the continent in midlatitudes and especially in the northern parts of the tropical deserts. This | The natural region is characterized by hot and dry summers and cold and dry winters. This means that the region receives rainfall only in winter. Summer here is somewhat long. The average temperature throughout the year is 8-25°C. The annual rainfall is 25-75 cm.&nbsp; These natural conditions are usually found in the areas along the Mediterranean Sea. The region consists of southern Europe, southwestern Asia and northern Africa along the Mediterranean Sea

(d) Monsoon region:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The monsoon zone generally extends from 10° to 30° north latitude to the north of the equatorial region and from 10° to 30° south latitude to the south. Areas affected by monsoon winds belong to this region. The main characteristic of the climate of the monsoon region is the change of seasons—hot and humid summers and cold and dry winters. The temperature difference between summer and winter is 15°C. The average annual rainfall is 200 cm. The area is dominated by deciduous plants as rainfall varies with the seasons. In winter, these plants lose their leaves due to lack of rainfall. The monsoon zone extends to tropical and subtropical latitudes. It belongs to the monsoon natural regions of South Asia including India, Southeast Asia, northeastern Australia, eastern Africa, eastern Brazil, Central America, etc. About 40 percent of the world's population lives in this monsoon region.

(e) Topography and climate of Asia&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The largest continent in the world is Asia ǀ Asia is covered with high mountain ranges, plateaus, river valleys, lowlands, coastal plains, islands, deserts, etc. Its central part is covered with mountains and plateaus. The Ural Mountains run north-south on the western border, the Himalayas and their tributaries, the Karakoram Mountains, and the Aravali Mountains, the highest mountains in the world, extend east-west in the middle. Everest (8,848 m) is the highest peak in the world in the Himalayas. The plateaus include the Tibetan Plateau, the highest Pamir Plateau, the Siberian Plateau, the Mongolian Plateau, the Southern Plateau, and the Iranian Plateau. The major rivers of the continent are the Amor, Huangho, Mekong, Yangtze, Ganges, Brahmaputra, Iravati, etc. The major ǀislands include Japan, Taiwan, Philippines, Java, Sumatra, Borneo, Silibis, Andaman and Nicobar Islands, Sri Lanka, Lakshadweep, Maldives, Bahrain etc. ǀ Its main deserts are Gobi ,Thar, Arabia etc. ǀ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The climatic variations of Asia, which extends from the equator almost to the North Pole, are particularly remarkable. The main climate types are tropical monsoon, tropical desert climate, temperate climate and polar climate. Vakhyansk, the coldest place on earth, is located in the Siberian region of Asia. Due to the tropical monsoon climate, the summers are hot and humid and the winters are dry and cold

(f) Tundra region:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The northernmost and southernmost parts of the Earth are covered with snow throughout the year. ǀ In the Northern Hemisphere, this region is usually located north of 661 ̊2 of the Arctic Circle. In winter, the temperature drops to -18°C. There is almost no rain here. In winter there is rather plenty of snow. No plants can grow in this area as it is covered with snow most of the year.&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;With some warming in summer, grasses, algae and teak plants grow in areas where the snow begins to melt. The area is mainly home to cold-tolerant animals such as tied deer, white foxes, white bears and seals. Residential land. This natural region of the North Pole is known as the Tundra region. This natural area includes the polar regions of Asia, Europe and North America in the northern hemisphere, including Greenland, and Antarctica in the southern hemisphere.

g) Earth's population and its distribution:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Earth's land mass consists of the continents of Asia, Africa, Europe, North America, South America, Oceania and Antarctica. The characteristics of the Earth's topography, climate, soil, plants, animals, etc. vary from place to place. These differences in the components of the natural environment cause the distribution of population and the way of life of people not to be the same everywhere in the world. &nbsp; Total population of the world 6.62 billion ǀ With a population of 4.41 billion, Asia is the most populous continent in the world ǀ About three-quarters of the world's population lives on this continent ǀ Africa has 944 million people 733 million ǀ 11 percent of the world's population ǀ population density of 32 people per square km ǀ total population of North America 523 million ǀ population density of 15 people per square km ǀ South America has a total population of 381 million ǀpopulation Density 12 people per square km ǀ 5.57 percent of the world's population ǀ Oceania has a total population of about 35 million ǀ (2007 estimates) and about 90 percent of the world's population lives in the Northern Hemisphere alone.

(h) Tropical grassland areas: In Africa and Australia, the region extends to 10°-25° north and south latitudes. Such grasslands have a special natural environment between equatorial and tropical desert regions. The climate of the tropical steppe region is characterized by warm and short summers and dry and long winters. Daily and seasonal temperature variations are high in this region. The rainfall during the year is moderate (25—100 cm). Due to this climate, herbaceous plants up to 3 meters tall have formed extensive grasslands in the area. Such grasslands in the tropics are known as savannahs. The Orrico River Basin in South America, the Brazilian Highlands and Venezuela, the northern and southern parts of the Zaire Basin in Africa, the East African Highlands and parts of South Africa, and the northern part of Australia belong to the tropical grassland region.       Tropical grasslands are very suitable for animal husbandry. Most of the area is commercial livestock farming ǀ the area is also home to various wildlife. Therefore, many of the inhabitants of this area earn their living by raising animals and hunting.  This area is very sparsely populated. Most of the tropical grasslands are socially and economically backward due to poor transportation and lack of essential production facilities.

i) Tropical hot desert regions:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Tropical deserts are usually located at the western ends of continents ǀ these deserts extend to the vicinity of the Cancer Eclipse (2312 ̊ north) and the Capricorn Eclipse (2312 ̊ south). The climate in this region is almost always hot and dry. The difference between day and night temperatures is large.&nbsp; In summer, the daytime temperature rises to 45°C. The rainfall is very low. The average annual rainfall is 20-25 cm.&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Due to lack of rainfall, only short grasses and thorny plants grow in parts of such desert areas. Much of this area is covered with sand. However, the desert gardens scattered around the desert grow some date palms and are cultivated to an equal extent.

j) Cold Simple Forests: Cold Simple Forests extend between 50-70° latitude in the Northern Hemisphere. It is bordered by the tundra region to the north and the mid-latitude grassland region to the south. This is. The climate of the region is somewhat dry and cold. In summer, temperatures rise to an average of 15 degrees Celsius. In winter, snow falls due to lower temperatures. Summer is shorter than winter in this region. There is some rainfall in summer.  The region extends from Scandinavia in Europe to the Pacific coast in the east and from Alaska in North America to the Atlantic coast in the east. It covers a large area of Europe, Asia and North America.
