The land mass of India has an area of 3.28 million square km. India’s total area accounts for about 2.4 per cent of the total geographical area of the world . From Figure 1.2 it is clear that India has a land boundary of about 15,200 km and the total length of the coastline of the mainland , including Andaman and Nicobar and Lakshadweep is 7,516.6 km. India is bounded by the young fold mountains in the northwest, north and northeast. South of about 220 north latitude, it begins to taper, and extend on its east. Look at Figure 1.3 and note that the latitudinal and longitudinal extent of the mainland is about 300. Despite this fact, the east-west extent appears to be smaller than the north-south extent. From Gujarat to Arunachal Pradesh, there is a time lag of two hours. Hence, time along the Standard Meridian of India (82030’E) passing through Mirzapur (in Uttar Pradesh)is taken as the standard time for the whole country . The latitudinal extent influences the duration of day and night, as one moves from south to north . Language: English
