(i) One of the distinct feature of the Peninsular Plateau is Deccan Trap.
(ii) Black soil area is called as Deccan Trap.
(iii) Deccan Trap is formed of igneous and metamorphic rocks.
1. Gradually with the passage of time, these rocks have denuded and are responsible for the formation of black soil.
(iv) The Aravali Hills lie on the western and north western margins of the Peninsular Plateau.
1. These are highly eroded hills and found as broken hills.
2. Extension of these hills are from Gujarat to south of Delhi in the south-east direction.

Comparison between the Himalayan peaks and the Peninsular peaks.

The Peninsular plateau is a tableland composed M old crystalline, igneous and metamorphic rocks. It was formed due to breaking and drifting of Gondwana land, thus making it a part of the oldest landmass. This plateau has broad and shallow valleys and rounded hills. The Peninsular plateau consists 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 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, Sind, Betwa and Ken, is from South-West to North-East, thus indicating the slope.
(iv) The Central Highlands are wider in the West, but narrower in the East.
(v) The eastward extensions of this plateau are locally known as Bundelkhand and Baghelkhand. The Chota Nagpur plateau marks the further eastward extension being drained by the Damodar river.
Deccan Plateau
This triangular area lies South of the Narmada. The Satpura mountain range marks its broad boundary in the 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 forcing the rain bearing moist monsoon winds to rise along the Western slopes of the ghats. The part of the plateau known as Deccan Trap contains black soil of volcanic origin.

The Central Highlands
(i) The part of the Peninsular Plateau lying to the north of the Narmada river covers a major area of the Malwa plateau.(ii) It is known as the Central Highlands.
(iii) The Vindhyan range bounds the Central Highlands on the south and the Aravallis on the northwest.
(iv) The further western extension gradually merges with the sandy and rocky desert of Rajasthan and Gangetic plain.
(v) The Central Highlands are wider in the west and goes on narrowing towards the east.
(vi) The eastward extensions of this plateau are locally known as the Bundelkhand in southern Uttar Pradesh.
(vii) Chhota Nagpur plateau marks the further eastward extension.

(i) Corsls are small, short lived, sedentary marine animals with a calcareous horny skeleton.
(ii) These thrive in shallow, mud free and warm wastewater grow into large colonies called coral reefs.
(iii) They secrete calcium carbonate (hard rock like substance). The coral secretion and their skeletons form coral deposits in the form of reefs.
(iv) They are mainly of three types: barrier reef, fringing reefs and atolls.
(v) Atolls are circular or horse shoe shaped coral reefs.
Examples: The Great Barrier Reef of Australia; and Lakshadweep Islands.

Features
The Central Highlands:
1. The part, of the Peninsular plateau lying to the north of the Narmada river covers a major area of the Malwa plateau, It is also known as The Central Highlands.
(i) The Vindhyan range bounds the Central Highlands on the south and the Aravallis on the north-west.
(ii) The further westward extension gradually merges with a sandy and a rocky desert of Rajasthan; and the Gangetic plain in south.
(iii) Rivers draining this region are the Chambal, the Sind. between the Ken and the Son. They flow from south-west to north-east thus indicating the slope.
2. The Central Highlands are wider in the west and go on narrowing towards the east .
3. The Eastward extensions of this plateau are locally known as the Bundelkhand and Baghelkhand in southern Uttar Pradesh. 
4. The Chhotanagpur plateau marks Ithe further eastward extension. It is drained by the Damodar river.
The Deccan Plateau:
5. The Deccan Plateau is a triangular landmass.
(i) It lies to the south of the river Narmada.
(ii) The Satpura ranges flank its broad base in the north while the Mahadev, the Kaimur hills, and the Maikal range are its eastern extension.
(iii) The Deccan plateau is higher in the west and slopes gently eastwards.
