PHYSIOGRAPHY
The present physiographic configuration of assam is geologically of
recent origin. It is characterised by diverse features such as
floodplains, marshes and beels, scattered hillocks,folded hill ranges
and old plateaus. The erosional and depositional process intensified by
heavy brainfall and frequent seismic movements play a dominant role in
shaping the physiography of Assam. However ,Asssam can be divided into
three major physiographic divisions:
1. The Brahmaputra valley
2. The hills of Karbi Anglong and North Cachar and
3. The Barak valley
