The peninsular plateau was formed by the breaking up of the Gondwanaland supercontinent. It consists of two broad divisions: the Central Highlands and the Deccan plateau. The Central Highlands lie north of the Narmada River and gradually merge with the deserts of Rajasthan in the west. The Deccan plateau extends from the Satpura and Vindhya ranges in the north to the Western and Eastern Ghats in the west and east. Major rivers draining this region flow from southwest to northeast.

2.  The peninsular plateau is a tableland composed of
the old crystalline, igneous and metamorphic rocks.
It was formed due to the breaking and drifting of
the Gondwanaland and thus making it a part of the
oldest landmass.
 This plateau consists of two broad divisions:
 Central highlands
 Deccan plateau.

3. I. The part of 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
northwest.
III. The further westward extension gradually merges
with the sandy and rocky desert of Rajasthan.

4.  The flow of rivers draining this region, namely the
Chambal, the Sind, the Betwa and Ken is from southwest
to northeast, thus indicating the slope.
 The central Highlands are wider in the west but
narrower in the east.
 Eastward extention: 1. Bundelkhand
2. Baghelkhand
3. The Chotanagpur plateau
drained by
Damodar river.

6. i. It extends over eight Indian states and encompasses a wide
range of habitats, covering most of central and southern India.
ii. It is located between three mountain ranges: the Western
Ghats form its western boundary, and the Eastern Ghats its
eastern boundary.  An extension of the plateau is also
visible in the northeast- locally known as
the Meghalaya, Karbi-Anglong Plateau
and North cacher hills. It is separated
by a fault from the Chotanagpur
Plateau. Three prominent hills ranges
from the west to east are the Garo, the
Khasi and the Jaintia hills.

7. i. Western Ghats lie parellel to the
western coast
ii. They are continuous and can be crossed
through passes only.
iii. Western Ghats are higher than
Eastern Ghats.
iv. The average elevation is 900 – 1600

8.  The Eastern Ghats stretch from the Mahanadi
valley to the Nilgiris in the South
 The Eastern Ghats are discontinuous and irregular
and dissected by rivers draining into the Bay of
Bengal.
