Question

Why the air temperature generally decreases from the equator to the pole

Answer 1

Explanation:

The temperature of the air decreases with the migration from the equator towards the poles. This change is due to the difference in atmospheric pressure.

When there is an increase in the altitudes, there are fewer air molecules which result in a decrease in the atmospheric pressure. This decrease in the pressure results in a drop in the temperature.

When one moves from the sea level to the higher altitudes, there is a change in the temperature due to the decrease in the pressure.

Both the assertion and reason are correct but the reason does not explain the assertion.

Thus, the correct answer is option B.
