PHYSICAL DIVISIONS • The Northern Indian Plains: • Lie to the south of the Himalayas. • Level and flat • Formed by alluvial deposits of the Ganga, Brahmaputra, Indus and its tributaries. • Provide fertile land for cultivation and population.
PHYSICAL DIVISIONS • The Great Indian desert • Western part of India. • Dry, hot and sandy stretch of land. • It has very little vegetation because of lack of moisture and unfavourable weather conditions. • Hence, it supports very little population.
PHYSICAL DIVISIONS • The Peninsular Plateau: • Triangular in shape • Relief is highly uneven • Aravali hills borders it on the north-west side. • The Vindhyas and the Satpuras are the important ranges. • West flowing rivers draining into Arabian Sea are Narmada and Tapi • Western and Eastern Ghats mark the western and eastern sides. • Western Ghats are continuous but the Easter Ghats are broken and uneven. • The plateau is rich in minerals like coal and iron-ore.
PHYSICAL DIVISIONS • The Coastal plains: • Plains found to the west of Western Ghats and East of Eastern Ghats. • Western coastal plains are narrow while the eastern ones are much broader. • There are many east flowing rivers like Mahanadi, Godavari, Krishna and Kaveri which drain into the Bay of Bengal. • They form fertile deltas at their mouths.

They are formed from the deposition of the sediment carried by the river as the flow leaves the mouth of the river. • Coastal Plains-a plain adjacent to a coast 16
