Question

The tropical deserts are located in the zone of which permanent pressure belt?

Options

• Equatorial low-pressure belt

• Sub-tropical high-pressure belt

• Subpolar low-pressure belt

• Polar high-pressure belt

Answer 1

Sub-tropical high-pressure belt

Explanation:

Tropical (hot) deserts form where the Hadley-cell air descends around 30° N and S, producing a permanent area of high pressure that suppresses cloud formation and precipitation. This produces very dry, warm conditions ideal for deserts; tropical deserts therefore occur roughly between about 15°–30° latitudes and commonly on the western margins of continents where the trade winds have already lost their moisture.
