ABSTRACT
The entry deals with the geomorphology of Northeast India. Geomorphology is intrinsically linked with the geological formations and lithology of any area. The region possesses both the oldest geological formations of the pre-Cambrian Era, i.e., the Meghalaya and the Karbi-Anglong Plateaus, and the youngest plains composed of very young soft sediments of Quaternary (Pleistocene–Holocene) origin. The highest point of the regions is Namchabarwa (7,600 m) in the Eastern Himalayas, and the lowest point is at Agartala plains (12.80 m). This entry also shows how the geology of the region is largely responsible for the geomorphological characteristics of the region.
