This tableland was formed when Gondwanaland broke and the pieces drifted apart. It is composed of old crystalline, igneous and metamorphic rocks. The Peninsular Plateau consists of both broad and shallow valleys, and rounded hills. 

The Peninsular Plateau has two broad divisions:The Central Highlands andThe Deccan Plateau
The Central Highlands refer to the portion of the Peninsular Plateau that lies to the north of the Narmada river and covers a majority of the Malwa Plateau.
