Do cold ocean currents cause deserts?
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 for the air to hold moisture. Most moisture falls as rain before it reaches the land, eg the Namib Desert in Africa.
Why do cold currents form in the desert?
Cold ocean currents have a direct effect on desert formation in west coast regions of the tropical and subtropical continents. There is fog and most of the areas are arid due to desiccating effect (loss of moisture).
How cold current is responsible for the desert?
The two currents partially responsible for the desert climate of Atacama and Kalahari desert are the cold Peruvian current and the cold Benguela current respectively.
What causes deserts to form?
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.
What is the coastal desert formed due to the influence of cold current?
yes costal desert are formed by cold ocean currents.
How are polar deserts formed?
Polar deserts are a category of cold deserts whose precipitation occasionally occurs in form of snow due to the limited moisture in the air and are localized to the polar regions of the Earth. These deserts are situated on the polar regions of the northern and southern hemispheres.
How is a cold desert formed?
It is formed due to atmospheric conditions that prevent rain. Cold deserts are formed in temperate regions, at higher altitudes and are located at the centre of the continent. Because of the low temperatures, pressure, moisture, distance from sea, and poor vegetation; precipitation is very low in these regions.
Which is a coastal desert formed due to the influence of a cold current?
Which ocean current is a cold current?
The cold current among the following given options is Labrador Current. This Labrador Current flows in the North Atlantic Ocean. The cold current flows till the Labrador coast from the Arctic Ocean. This cold wave also meets the warm waves that are moving and outward in Gulf Stream.

How are sandy deserts formed?
This sand was washed in by rivers or streams in distant, less arid times – often before the area became a desert. 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.
