Question

Why are most deserts located at 30 degrees latitude?

A) It is where the heated equator air starts to fall.
B) Increased humidity leads to precipitation elsewhere.
C) High-pressure systems promote dry weather.
D) Interference from adjacent mountain ranges blocks rainfall.

Answer 1

Deserts are located at 30 degrees latitude due to high-pressure systems, rain shadow effect, and interference from mountain ranges.

Step-by-step explanation:

Most deserts are located at 30 degrees latitude for a few reasons. First, at that latitude, high-pressure systems promote dry weather, resulting in less precipitation. Second, deserts are often found on the downwind or lee side of mountain ranges, which create a rain shadow effect. This means that prevailing winds drop their water content on the mountains, leaving dry air on the other side, where the desert forms. Finally, interference from adjacent mountain ranges can block rainfall, further contributing to the arid conditions.
