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 consists of broad divisions, namely, the central
highlands and the Deccan plateau. (5)
Three distinct features of peninsular
plateau are
A. 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. (2)
B. Deccan Plateau This
triangular area lies South of the Narmada. The Satpura mountain range marks its
broad boundary in North. The deccan plateau is higher in the West and slopes
gently east wards. An extension of it is visible in the North-East. The plateau
is separated from the hills in the North-East by a geological fault. The
hillsare Garo, Khasi and
Jaintia.

C. The Western Ghats and the
Eastern Ghats The Western Ghats and the Eastern Ghats mark the Western and the
Eastern edges of the deccan plateau. Western ghats lie parallel to the Western
coast and they are continuous. The Eastern Ghats are discontinuous and stretch
from Mohana valley to the Nilgivis in the South. The Western Ghats are higher
than the Eastern Ghats. (1)
