Question

Regions dominated by subsiding air are typically ________, while regions dominated by rising air are typically ________.

options:

	dry, wet
	warm, cold
	cold, warm
	wet, dry

Answer 1

SOLUTION:-

Ans:- dry, wet.

Explanation:- When the air is subsiding to the ground, the air parcel becomes compressed due to increasing preesure. Generally, the air becomes warm and relative humidity is increased. That's why the air becomes unsaturated and no rainfall is happened there. Finally, the region becomes dry. For example, subtropical region (30°N/S) , where dry and high pressure region is present due to subsiding of air.

On the other hand, when air start to rise , after certain height, the air becomes saturated and condensed due to Adiabatic cooling. And cloud is formed and rainfall is happened there. That's why, in equatorial region wet condition is present because of rising of air parcel.

Wrong option:-

** Warm, cold :- when the air parcel start to subside, it becomes warm but the region becomes dry due to warm and unsaturated air.

When the air start to rise, the air becomes cool and saturated and the region becomes wet due to rain fall.
