Location, Extent, and Physical Features
Location of India
India is situated in the Northern and Eastern Hemispheres, extending from latitudinal coordinates 8°4′ N to 37°6′ N and longitudinal coordinates 68°7′ E to 97°25′ E. The Tropic of Cancer (23½° N) traverses almost the center of India, demarcating tropical from subtropical areas. The country's Standard Meridian (82½° E), located near Mirzapur, is essential for determining Indian Standard Time (IST).
Extent and Size of India
India holds the title of the seventh-largest country globally, covering 3.28 million square kilometers. Its dimensions span approximately 3,214 km in a north-south direction and 2,933 km in an east-west direction, possessing a land frontier of about 15,200 km and a coastline of 7,516.6 km, which includes the coastal territories of its islands.
India’s Neighbours
India shares its borders with seven countries: Pakistan and Afghanistan to the northwest; China, Nepal, and Bhutan to the north and northeast; and Bangladesh and Myanmar to the east. Additionally, Sri Lanka and the Maldives are its maritime neighbors.
Significance of India’s Location
India's strategic position in the Indian Ocean enhances its sea trade and has historically established it as a crossroads for cultural and economic interactions between East and West Asia. The extensive coastline has facilitated maritime links and international traders for centuries.
Major Physical Divisions of India
India’s landscape can be categorized into six main physiographic divisions:
1. The Northern Mountains: Comprises the Himalayas, including the Himadri (highest peaks), Himachal (hill stations), and Shiwaliks (foothill ranges).
2. The Northern Plains: Fertile alluvial plains formed by the Indus, Ganga, and Brahmaputra river systems.
3. The Peninsular Plateau: The oldest landmass formed by tectonic activity with rich mineral deposits and significant river systems like the Narmada and Godavari.
4. The Indian Desert: Located in western Rajasthan, known as the Thar Desert, characterized by sandy soil and sparse rainfall.
5. The Coastal Plains: Coastal strips alongside the Arabian Sea and Bay of Bengal, featuring major deltas.
6. The Islands: Including the Andaman and Nicobar Islands (volcanic origin) and Lakshadweep Islands (coral origin).
Importance of India’s Physical Features
The mountains influence climate patterns and biodiversity. The plains support intensive agriculture and are densely populated. Plateaus contribute to mineral wealth and distinct farming practices. Coastal regions offer avenues for trade and tourism, whereas islands enhance biodiversity and security concerns.
