Explain why nomadic tribes need to move from one place to another. What are the advantages to the environment of this continuous movement?

Explanation

The Nomadic tribe move one place to another in search of new pastures. When the season becomes unfavourable and the grass of a particular region is exhausted, the tribe moves to another area. The seasonal movement of the nomadic tribe is also beneficial for the environment. It allows natural re-growth of grass in the pastureland.
