Why do deserts occur at 30n and 30s?
Most of the world’s deserts are located near 30 degrees north latitude and 30 degrees south latitude, where the heated equatorial air begins to descend. The descending air is dense and begins to warm again, evaporating large amounts of water from the land surface. The resulting climate is very dry.
What is a rainshadow desert?
Rain shadow deserts are created when mountain ranges lie parallel to moist, coastal areas. Prevailing winds moving inland cool as air is forced to rise over the mountains. Carried moisture falls on slopes facing the winds. When the winds move over the crest and down the far side, they are very dry.

- Isolation (exposure to sun rays) is absent in winter, and intense and continuous in summer.

What are main features of desert?
Desert Description Deserts are characterized by low humidity (air moisture), low annual rainfall, and an overall moisture deficit, meaning the rate of evaporation exceeds the rate of rainfall on average. Deserts are also characterized by extreme temperatures.
