Give main characteristics of the division of Great Peninsular Plateau.
The Great Peninsular Plateau is the oldest landmass of the Indian subcontinent. It is divided into two parts:
The Central Highlands
These highlands are made up of hard igneous and metamorphic rocks.
- The old Aravalli range borders it in the north-west.
- The Central Highlands further consist of the Malwa Plateau in the west and Chotanagpur region in the east.
- The eastward extension of the Malwa Plateau is known as Bundelkhtmd and Baghelkand in southern U.P. and northern M.P.
- The Malwa Plateau is drained by the southern tributaries of the Yamuna and the Ganga. Damodar river drains the Chotanagpur plateau.
The Deccan Plateau
- The Deccan Plateau extends from river Narmada to the Southern tip of the Peninsular India.
- It is one of the oldest earth blocks and is made up of hard igneous and metamorphic socks.
- The Satpura range -northern Mahadev Hills, Maikal range etc. form its northern edge eastern.
- The Western Ghats form its Western edge which is much steeper and higher than the eastern one. The plateau slopes gently towards the east.
- The Eastern edge is marked by Eastern Ghats which are broken into small hills by rivers.
