Assertion (A): Variations in pressure cause horizontal movements of air called winds.
Reason (R): Winds transport heat and moisture from one region to another and affect both temperature and humidity.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R does not explain A.
- A is true but R is false.

Answer
Both A and R are true but R does not explain A.
Explanation — Contrasts in temperature cause changes in air density, which are responsible for variations in pressure. These variations cause horizontal movements of air called winds. Winds transport heat and moisture from one region to another and thus help in the occurrence of precipitation and affect both temperature and humidity.
