Question

what is a desert ?
Desert is an arid region characterised by extremely high or low temperature and has scarce vegetation​

Answer 1

A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation. About one-third of the land surface of the world is arid or semi-arid.
