The document discusses the Peninsular Plateau of India. It is located south of the Northern Plains and was formed from the breaking and drifting of the Gondwana landmass, making it one of India's oldest landforms. The Peninsular Plateau is a tableland made up of old crystalline and metamorphic rocks with broad shallow valleys and rounded hills. It is flanked by mountain ranges on its edges and contains important mineral resources. The plateau is divided into the Central Highlands and Deccan Plateau regions which contain more specific geographical features.
