Study Notes
Physical Features of India
- The Indian mainland is accompanied by two groups of islands in the Bay of Bengal, Andaman and Nicobar islands, which are bigger in size and more numerous.
The Coastal Plains
- The coastal plains along the Bay of Bengal are wide and level, with the northern part referred to as the Northern Circar and the southern part as the Coromandel Coast.
- Large rivers like the Mahanadi, Godavari, Krishna, and Kaveri have formed extensive deltas on this coast.
- Lake Chilika is an important feature along the eastern coast, which is the largest saltwater lake in India, located in the state of Odisha.
The Indian Desert
- The Indian Desert lies towards the western margins of the Aravali Hills, characterized as an undulating sandy plain covered with sand dunes.
- The region receives very low rainfall below 150 mm per year, has an arid climate with low vegetation cover, and has streams that appear during the rainy season but disappear soon after.
- Luni is the only large river in this region.
Islands
- The island group has great diversity of flora and fauna, with the Pitti island having a bird sanctuary.
- Coral polyps, short-lived microscopic organisms, flourish in shallow, mud-free, and warm waters, secreting calcium carbonate and forming coral reefs of three kinds: barrier reefs, fringing reefs, and atolls.
Peninsular Plateau
- The Peninsular plateau is flanked by narrow coastal strips, running along the Arabian Sea on the west and the Bay of Bengal on the east.
- The western coast is a narrow plain consisting of three sections: the Konkan (Mumbai – Goa), the Kannad Plain, and the Malabar coast.
- The Aravali Hills lie on the western and northwestern margins of the Peninsular plateau, which are highly eroded hills and are found as broken hills from Gujarat to Delhi in a southwest-northeast direction.
- The Decean Trap is a black soil area of volcanic origin, which has denuded over time and is responsible for the formation of black soil.
