Precipitation MCQ with answer and solution

Concept

Precipitation caused by pressure difference

Formula

NONE

Step-by-step solution

1. Cyclonic precipitation is caused by the lifting of an air mass due to pressure differences between regions. 2. Air flows from high-pressure to low-pressure areas, creating a cyclone that forces air to rise and condense. 3. Convective precipitation results from local thermal heating rather than large-scale pressure differences. Answer: D

Explanation

Cyclonic precipitation occurs when air masses are forced to rise due to atmospheric pressure differences and convergence in low-pressure zones. As the air mass flows into the low-pressure region, it ascends, cools adiabatically, and condenses to form rain or snow. Therefore, precipitation driven directly by pressure gradients and surrounding air convergence is classified as cyclonic precipitation.

Why the other options are wrong

A) Natural precipitation is a general umbrella term rather than a specific lifting mechanism. B) Organic precipitation is not a recognized classification of precipitation. C) Convective precipitation is caused by thermal updrafts due to surface heating.

Shortcut

Pressure differences and low-pressure systems drive Cyclonic precipitation.

Common mistake

Confusing cyclonic precipitation driven by pressure differences with convective precipitation driven by thermal air rising.
