    • They are bound by the Vindhya Range from the south and by the Aravalli hills from the north-west.
    • The further westward extension gradually merges with the sandy and rocky desert of Rajasthan.
    • The flow of the rivers draining this region, namely the Chambal, the Sind, the Betwe and Ken is from south-west to north-east.
    • The central highlands are wider in the west but narrower in the east.
    • The eastward extensions of their plateau are locally known as ‘Bundelkhand’ and Baghelkhand.
