Why do deserts form?
Deserts in hot climates owe their
origin to lack of water resulting from the capacity of warm air above the
desert area to retain most of the available moisture. This, combined with the
high evaporation rate, turn the land into desert.
Another factor in the formation of deserts is a high
mountain range, such as the Andes. These enormous mountains lie across the path
of the rain clouds and moist winds, thus forming a shield.
So most of the rain clouds burst over the mountains
before they ever reach the plains. Other deserts, such as the Gobi in Central
China, are so deep within the continent that the moisture-laden winds hardly
ever reach them.
