3. The Northeastern Plateau:
* The Meghalaya (or Shillong) plateau is separated from peninsular rock base by the Garo-Rajmahal gap.
Shillong (1,961 m) is the highest point of the plateau.
* The region has the Garo, Khasi, Jaintia and Mikir (Rengma) hills.
An extension of the Meghalaya plateau is also seen in the Karbi Anglong hills of Assam.
* The Meghalaya plateau is also rich in mineral resources like coal, iron ore, sillimanite, limestone and uranium.
* This area receives maximum rainfall from the south-west monsoon. As a result, the Meghalaya plateau has a highly eroded surface.
* Cherrapunji displays a bare rocky surface devoid of any permanent vegetation cover.
