On the basis of its physiographic characteristics the Peninsular Upland may be divided into a number of sub-units. These include hill ranges like the Aravallis, Vindhyas, Satpuras, Sahyadris, the Eastern Ghats; plateaus like Chotanagpur, Meghalaya, Deccan, Karnataka, Tamil Nadu, Andhra, Bundelkhand; and fertile plains like Malwa, Clihattisgarh etc. Following S.P. Chatteijee (1964) the region has been subdivided into 8 macro and 25 meso physiographic units.
