Question

Answer the following questions subjectively:

What is the extent and surface formation of Peninsular plateau? Describe its different subdivisions on the basis of slope of the land.

Accepted Answer

The Malwa plateau encompasses a large portion of the central highlands. It stretches from the Aravallis in the west to the Ganges valley in the north and east, and from the Vindhyas in the south. The Aravallis are residual mountains, also known as Relic Mountains. This Vindhyan plateau is made up of long, narrow ridges of Quartzite rocks. The Chotta Nagpur plateau, drained by the Damodar river, lies to the east. This plateau is India's mineral repository.

• The Vindhyas range runs from east to west in the Narmada Valley. It divides Northern and Southern India. It has an average height of $300$ metres. It runs from Gujarat in the west to Bihar in the east, passing through Madhya Pradesh.

• The Satpuras are a mountain range located between the Narmada and Tapti rivers. They stretch from Gujarat to Amarkantak in the east. The highest point of these ranges is Dhupgarh ( $1350$ metres).

The Deccan Plateau is located south of the Narmada River. It is surrounded on three sides by mountain ranges: the Western Ghats, the Eastern Ghats, and the Satpuras. The Deccan plateau is a slanted plateau with an eastward slope. Its average height ranges from $500$ to $1000$ metres.

Rivers have subdivided this plateau into numerous subdivisions. The NW Deccan plateau is composed of lava and is known as the Deccan trap.

The Western Ghats stretch for about $1500$ kilometres from Tapti Valley to Kanyakumari. Thai ghat, Bhor ghat, and Pal ghat are the three passes. These mountains rise abruptly from the sea. Short, swift streams flow westward without forming deltas. The average elevation is around $1200$ metres. The Godavari, Krishna, and Cauvery rivers originate in the Western Ghats and flow eastward. The highest peak is Anai Mudi ( $2698$ metres).

The Eastern Ghats The Eastern Ghats stretch for about $800$ kilometres from the Mahanadi valleys to the Nilgiris. These are not linear ranges. Rivers create large chasms. The southern region is home to the Javadi, Shevroy, and Nallamalai bills.

The western and eastern Ghats meet in the south, where they form the Nilgiris. The highest peak in the Nilgiris is Doda Beta ( $2637$ metres).
