4. Give brief explanatory answer of the following (Alternatives should be noted):

4.1 Why wind action is dominant in desert regions?
Ans: Wind action is dominant in desert region because, compared with water, air has low density and viscosity. So, only very fine particles can be carried by it in suspension. Wind is active in areas that lack vegetative cover. Therefore, in dry areas lacking vegetation wind is by far the most predominant geomorphic agent.

Ans: Sea Breeze:-
i. During day when when air moves from sea to land, is known as sea breeze.
ii. In sea breeze air pressure in lower over the land than the sea.

i. During night when air moves from land to sea, is known as land breeze.
ii. In land breeze air pressure is lower over the land than the sea.
iii . So in land breeze air moves from land to sea.

4.2 State the differences between biodegradable and non-biodegradable wastes.
