Assertion (A): Areas near the equator receive rainfall throughout the year. Reason (R): High temperatures and high humidity cause convectional rain in most afternoons near the equator. In the context of the above two statements, which one of the following is correct?
- ABoth A and R are true and R is the correct explanation of ACorrect
- BBoth A and R are true but R is not a correct explanation of A
- CA is true but R is false
- DA is false but R is true
Explanation
The correct option is A because both statements are scientifically accurate and directly linked.
Assertion A is true because the equatorial region is characterized by a lack of distinct seasons, resulting in consistent precipitation throughout the year.
Reason R explains the mechanism behind this rainfall. Due to the intense vertical sun rays at the equator, the surface undergoes significant heating. This causes the air to rise rapidly, carrying moisture from high humidity. As this air rises, it cools and condenses, leading to heavy convectional showers, typically occurring in the afternoons. Since this process happens daily, it directly explains why these areas receive rainfall year round.
