Where are most deserts located Why?
Answer: Most of the worlds deserts are located in the western margins of continents in the subtropics because the prevailing winds in the tropics are tropical easterly winds. The tropical easterly winds become dry by the time they reach the western margins of the continents and so they bring no rainfall.
Similarly Why are deserts located where they are located? Deserts are often found towards the west of continents. Some deserts are found on the western edges of continents. They are caused by cold ocean currents, which run along the coast. They cool the air and make it harder to hold moisture.
Where are deserts located latitude? Deserts cover around 20% of the Earth and are on every continent. They are mainly found around 30 to 50 degrees latitude, called the mid-latitudes. These areas are about halfway between the equator and the north and south poles.
Beside above Why are deserts in the west?
These are the results of the prevailing easterly winds of the tropics, which are the trade winds. … These winds become dry when they reach the western sides of the continents, and hence don’t bring any rain with them. As these regions become devoid of moisture, deserts are formed.
Why are deserts near the Equator?
Subtropical deserts are caused by the circulation patterns of air masses. … Hot, moist air rises into the atmosphere near the Equator. As the air rises, it cools and drops its moisture as heavy tropical rains. The resulting cooler, drier air mass moves away from the Equator.
Why are deserts found in western sides? The trade winds prevail in the lower portion of the earth’s atmosphere, in the lower section of the troposphere. These winds become dry when they reach the western sides of the continents, and hence don’t bring any rain with them. As these regions become devoid of moisture, deserts are formed.
Why deserts are found? Interior deserts, which are found in the heart of continents, exist because no moisture-laden winds reach them. By the time air masses from coastal areas reach the interior, they have lost all their moisture. Interior deserts are sometimes called inland deserts.

Why are deserts found in the same latitudes?
Desert formation in these particular latitudes is primarily due to complex global air-circulation patterns caused by the rotation of the earth on its axis (earth moves at great speed near the equator and slowly near the poles), the seasonal tilting of the earth in relation to the sun, and other factors.
What caused deserts? 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. … Rocks are smoothed down, and the wind sorts sand into uniform deposits. The grains end up as level sheets of sand or are piled high in billowing sand dunes.
Where is the Sahara desert located?
The Sahara is the world’s largest desert; it extends across most of the northern part of Africa.
Why are most of the desert located in the western side of the continents? Answer: Most of the worlds deserts are located in the western margins of continents in the subtropics because the prevailing winds in the tropics are tropical easterly winds. The tropical easterly winds become dry by the time they reach the western margins of the continents and so they bring no rainfall.

Why are deserts found at the tropics?
Because the tropics are largely cloudless they get very hot during the day. There are few clouds to insulate these areas during the night. Therefore, temperatures drop to very low levels overnight.
Why Most deserts are located on the western part of a continent? Answer: Most of the worlds deserts are located in the western margins of continents in the subtropics because the prevailing winds in the tropics are tropical easterly winds. The tropical easterly winds become dry by the time they reach the western margins of the continents and so they bring no rainfall.
Where is the largest desert in the world located? Sand dunes in the Sahara, near Merzouga, Morocco. The Sahara is the world’s largest desert; it extends across most of the northern part of Africa.
Where is the Antarctic desert located?
The Antarctic Polar Desert covers the continent of Antarctica and has a size of about 5.5 million square miles. The second-largest desert is the Arctic Polar Desert. It extends over parts of Alaska, Canada, Greenland, Iceland, Norway, Sweden, Finland, and Russia. It has a surface area of about 5.4 million square miles.
How are deserts distributed on earth? Most deserts are distributed around the globe based on the global circulation patterns and are located along a belt centered on the 30° North and 30° South latitude lines. Other geological settings that can cause desert formation are extreme distance from oceans and cold ocean currents.
Why do deserts get no rain?
Why is there no rain in the desert? A desert is a region of land that is very dry because it receives low amounts of precipitation (usually in the form of rain, but it may be snow, mist or fog), often has little coverage by plants, and in which streams dry up unless they are supplied by water from outside the area.
Why are deserts cold at night? During the day, sand’s radiation of the sun’s energy superheats the air and causes temperatures to soar. But, at night most of the heat in the sand quickly radiates into the air and there is no sunlight to reheat it, leaving the sand and its surroundings colder than before.
Why do deserts have sand?
Once a region becomes arid, there’s no vegetation or water to hold the soil down. Then the wind takes over and blows away the finer particles of clay and dried organic matter. What’s left is desert sand. … Sometimes an entire desert has migrated due to movement of Earth’s huge overlying land plates.
Where is Kalahari desert located? Kalahari Desert, large basinlike plain of the interior plateau of Southern Africa. It occupies almost all of Botswana, the eastern third of Namibia, and the northernmost part of Northern Cape province in South Africa.
