How is desert formed?
Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods.
What is a subtropical desert?
Subtropical deserts are very hot and dry in the summer and cooler but still dry in the winter. Rainfall happens in short bursts. The air is so hot and dry in these deserts that sometimes rain evaporates before it even has a chance to hit the ground!
How does a rain shadow desert form?
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. Moisture falls on slopes facing the winds. When the winds move over the mountain crests and down the far side, they are very dry.
What are the causes for the formation of tropical desert?
The nine causes are: (1) Natural Situation (2) Air Circulation Pattern (3) Currents: A Hot Water Heating System (4) Oceanic Currents (5) Remote Situation From an Oceanic Moisture (6) Mountain Barrier (7) Rainless (8) Temperature and (9) Man in Desert Making. The world has always had its deserts.
What are the four causes of deserts?
Various Causes of Desertification
- Overgrazing.
- Deforestation.
- Farming Practices.
- Excessive Use of Fertilizers and Pesticides.
- Overdrafting of groundwater.
- Urbanization and Other Types of Land Development.
- Climate Change.
- Stripping the Land of Resources.
What is a cold desert called?
Cold deserts are found in the Antarctic, Greenland, Iran, Turkestan, Northern and Western China. They are also known as polar deserts. These deserts are generally found in certain mountainous areas.

How are deserts formed in the tropics?
How Is a Desert Formed? Most deserts are formed in high-pressure subtropical areas caused by the equatorial wind belts. These are produced with the hot air from Ecuador, which is always increasing; descending into the tropics, it is too dry – the rains have already occurred over the tropics, and the air itself is warmer and less humid.
Where are subtropical deserts located in the world?
Subtropical desert s are caused by the circulation patterns of air mass es. They are found along the Tropic of Cancer, between 15 and 30 degrees north of the Equator, or along the Tropic of Capricorn, between 15 and 30 degrees south of the Equator. Hot, moist air rises into the atmosphere near the Equator.
What kind of climate does the desert have?
Tropical and subtropical desert climate, major climate type of the Köppen classification dominated in all months by the subtropical anticyclone (or subtropical high), with its descending air, elevated inversions, and clear skies. Such an atmospheric environment inhibits precipitation.
Where does the process of desertification usually occur?
Desertification is the process of productive cropland turning into non-productive, desert-like environments. Desertification usually happens in semi-arid areas that border deserts. Desertification usually happens in semi-arid areas that border deserts.
