India－Location
India's location on the globe is central to understanding its geography, climate, and culture. The country has a vast and varied landscape, stretching across thousands of kilometers.
Latitudinal and Longitudinal Extent
The mainland of India extends from Kashmir in the north to Kanniyakumari in the south, and from Arunachal Pradesh in the east to Gujarat in the west.
- Latitudinal Extent: The mainland stretches from 8°4' N to 37°6' N.
- Longitudinal Extent: The mainland stretches from 68°7' E to 97°25' E.
- Southernmost Point: While the mainland's southern tip is Kanniyakumari, India's overall southern boundary extends to 6°45' N latitude in the Bay of Bengal, which includes the Andaman and Nicobar Islands.
- Territorial Limit: India's sovereignty extends into the sea up to 12 nautical miles (about 21.9 km) from the coast.
Note
A nautical mile is a unit of measurement used for maritime and air navigation. It is slightly longer than a regular (statute) mile.
- 1 Nautical mile = about 1.8 km
- 1 Statute mile = about 1.6 km
Implications of India's Vast Extent
India's latitudinal and longitudinal spread is roughly 30 degrees each. However, this vastness has different effects on distance and time.
Distance Discrepancy
Even though the latitudinal and longitudinal degree spans are similar, the actual distances are not.
- The north-to-south distance is 3,214 km.
- The east-to-west distance is 2,933 km.
The reason for this difference is that the distance between lines of longitude decreases as they get closer to the poles, whereas the distance between lines of latitude remains the same everywhere.
Impact of Latitude
India's latitudinal position is responsible for its diverse climate and natural environment.
- The southern part of the country lies within the tropics.
- The northern part lies in the sub-tropical zone, also known as the warm temperate zone.
- This split location results in significant variations in landforms, climate, soil types, and natural vegetation across the country.
Impact of Longitude and Indian Standard Time (IST)
The nearly 30-degree longitudinal spread creates a significant time difference between the eastern and western parts of India.
- There is a time difference of nearly two hours between the easternmost point in Arunachal Pradesh and the westernmost point in Gujarat.
- To avoid confusion and have a uniform time for the entire country, India follows Indian Standard Time (IST).
- IST is based on the Standard Meridian of India, which is 82°30' E. There is a general understanding among countries to select their standard meridian in multiples of 7°30' of longitude, which is why 82°30' E was chosen.
- This means that while the sun rises much earlier in northeastern states like Nagaland compared to Jaisalmer in the west, the watches in all parts of India show the same time.
- Indian Standard Time is 5 hours and 30 minutes ahead of Greenwich Mean Time (GMT).
Example
Some countries with a very large east-to-west expanse, like the USA, have multiple time zones to account for the difference in solar time. The USA has seven different time zones.
Size
India's large size is a defining feature of its geography and contributes to its immense diversity.
- Area: India covers an area of 3.28 million sq. km.
- World's Land Surface: This makes up 2.4 per cent of the world's total land area.
- Global Rank: India is the seventh largest country in the world by land area.
Physical Diversity and the Indian Subcontinent
India's vast size has endowed it with a great variety of physical features:
- Mountains: Lofty mountain ranges like the Himalayas in the north.
- Rivers: Large rivers such as the Ganga, Brahmaputra, Mahanadi, Krishna, Godavari, and Kaveri.
- Hills: Green, forested hills in the northeast and south India.
- Desert: The vast sandy expanse of the Marusthali (Thar Desert).
These features help form a distinct geographic entity known as the Indian subcontinent.
- Boundaries: The subcontinent is bounded by the Himalayas in the north, the Hindukush and Sulaiman ranges in the northwest, the Purvachal hills in the northeast, and the vast Indian Ocean in the south.
- Countries Included: The Indian subcontinent includes Pakistan, Nepal, Bhutan, Bangladesh, and India.
- Historical Barrier: The Himalayas have acted as a formidable physical barrier in the past, contributing to the subcontinent's unique regional identity. It was difficult to cross except through a few mountain passes like the Khyber, the Bolan, the Shipkila, the Nathula, and the Bomdila.
Coastline
The peninsular part of India extends into the Indian Ocean, giving the country a long and significant coastline.
- Mainland Coastline: The length of the coastline for the Indian mainland is 6,100 km.
- Total Coastline: The total geographical coastline, including the island groups of the Andaman and Nicobar in the Bay of Bengal and Lakshadweep in the Arabian Sea, is 7,517 km.
- This extensive coastline provides India with a wealth of varied resources.
India and its Neighbours
India's location in Asia is strategically important, shaping its relationships with other countries.
- Continental Location: India is situated in the south-central part of the continent of Asia.
- Maritime Location: It borders the Indian Ocean and its two major arms, the Bay of Bengal to the east and the Arabian Sea to the west. This maritime position has provided crucial links for trade and travel with neighboring regions via sea and air routes.
- Island Neighbours: In the Indian Ocean, India's neighbours include two island nations:
- Sri Lanka: Separated from India by the Gulf of Mannar and the Palk Strait.
- Maldives
