THE PENINSULAR PLATEAU

What is Peninsula? A body or piece of land enclosed on three sides by water, jutting out from a larger body of land.

The Peninsular Plateau Location The Peninsular Plateau lies to the south of the Northern Plains of the India.

The Peninsular Plateau It was formed due to the breaking and drifting of the Gondwana land. Hence, it is a part of the oldest landmass.

The Peninsular Plateau It is a tableland made up of the old crystalline, igneous and metamorphic rocks. The plateau has broad and shallow valleys and rounded hills.

The Peninsular Plateau The Peninsular Plateau is flanked by the Aravallis on the northwest, the Western Ghats in the west and the dissected Eastern Ghats in the east.

The Peninsular Plateau Many rift valleys such as Narmada, Tapi, Mahanadi, Godawari, and Damodar have been formed due to faulting and vertical movements.

The Peninsular Plateau The Deccan Trap is famous for black soils. The Peninsular Plateau is rich in valuable minerals such as manganese, iron, mica, coal, bauxite, gold and copper.

Divisions of the Peninsular Plateau A)The Central Highlands B)The Deccan Plateau 1.The Malwa Plateau 1.The Deccan Trap 2.The Bundelkhand 2.The Western Ghats 3.The Baghelkhand 3.The Eastern Ghats 4.The Chotanagpur 4.The North – East plateau extension

A)The Central Highlands The northern part of the Peninsula, north of the Vindhyas, is known as the Central Highlands.

The Central Highlands The flow of the rivers of this region is from southwest to northeast.

Boundaries of the Central Highlands The Central Highlands are bounded by Aravali range on the northwest, Ganga plains on the north and Vindhya range on the south. The Central Highlands are wider in the west but narrower in the east.

1.The Malwa Plateau Malwa Plateau, plateau region in north-central India. It is bounded by the Madhya Bharat Plateau and Bundelkhand Upland to the north, the Vindhya Range to the east and south, and the Gujarat Plains to the west. Of volcanic origin, the plateau comprises central Madhya Pradesh state and southeastern Rajasthan state. The name Malwa is derived from the Sanskrit malav (part of the abode of Laksmi [goddess of wealth]).

1.The Malwa Plateau The Malwa Plateau ranges in elevation from about 1,650 to 2,000 feet (500 to 600 meters); erosion has carved the ancient lava flows into isolated mesas found throughout the plateau, together with an occasional sandstone hill. The western part of the region is drained by the Mahi River, the middle section by the Chambal River, and the eastern part by the Betwa River and the headwaters of the Dhasan and Ken rivers. Other rivers include the Parbati, Sipra, Gambhir, and Choti Kali Sindh, their valleys flanked by terraced slopes. Vegetation is of the savanna type with scattered teak and sal (Shorea robusta) forests.

4.The Chotanagpur Plateau Location: North east of Arrvalli ranges. It is spread up to the great bend of the Ganges river. Many important minerals such as iron, manganese , copper, lead, zinc, and gold.

B) The Deccan Plateau Total area :127,700sq miles The rest of the southern India is a signal plateau unit. Height:900m in west &300m in east It has slope south eastward. north western part covered with lava .River Krishna and Penne flow towards andhra . Importance for minerals like Coal,iron,Gold,manganese

2.The Eestern Ghats & Western Ghats The Eastern and Western ghats are the edges of the Deccan Plateau in both directions. The western ghat lie the parallels to the eastern coast. The western ghat is continuous and can be cross through passes. (Thal, bhor,pal ghats ) The height of western ghat about 900m to 1600m The height of Eastern ghat is 600m only. The eastern ghat stretches from Mahanadi valley to the nilgiri hills in the south. The Eastern ghats are discontinuous and cuts by the rivers.
