Answer:

                  The Peninsular plateau is a table land composed of the old crystalline, igneous and metamorphic rocks. It was formed due to breaking and drifting of the Gondwana land and thus making it a part of oldest landmass. This plateau has broad and shallow valleys and rounded hills. The Peninsular plateau consist of two broad divisions, namely, the Central Highlands and the Deccan plateau. Central Highlands (i) The part of the Peninsular plateau lying to the North of the Narmada River covering a major area of the Malwa plateau is known as the Central Highlands. (ii) The Vindhyan range is bounded by the Central Highlands on the South and the Aravalis on the North-West. The Westward extension gradually merges with the sandy and rocky desert of Rajasthan. (iii) The flow of the rivers draining this region namely the Chambal, the Sind, the Betwa and Ken is from South-West to North-East, thus indicating the slope. (iv) The Central Highlands are wider in West, but narrower in the East. (v) The Eastward extensions of this plateau are locally known as the Bundelkhand and Baghelkhand. The Chhotanagpur plateau marks the further Eastward extensions drained by the Damodar river. Deecan Plateau This triangular area lies South of the Narmada. The Satpura mountain range marks its broad boundary in North. The plateau is separated from the hills in the North-East by a geological fault. The hills are Garo, Khasi and Jaintia. The Western Ghats cause orographic rain by facing the rain bearing moist monsoon winds to rise along the Western slopes of Ghats. The parts of the plateau known as Deccan traps contains black soil of volcanic origin.
