Why are there hot and cold deserts?

Hot deserts are characterized by high temperatures and low precipitation. They are found in tropical and subtropical regions, where the sun's rays are strong and the air is dry. The lack of moisture prevents plants from growing, and the sand and rocks absorb the heat from the sun, creating a hot and arid environment. Some of the hottest deserts in the world include the Sahara Desert in Africa, the Arabian Desert in the Middle East, and the Sonora Desert in North America.

Cold deserts:

Cold deserts are characterized by low temperatures and low precipitation. They are found in polar regions and high mountain areas, where the air is cold and the ground is often frozen. The lack of moisture prevents plants from growing, and the snow and ice reflect the sun's rays, creating a cold and desolate environment. Some of the coldest deserts in the world include the Arctic Desert in the Arctic region and the Antarctic Desert in Antarctica.
