Where are deserts located in the world?

Deserts are found throughout the world, especially in Africa and Australia. The world’s largest desert is the Sahara, which covers nearly all of northern Africa.

Where are most deserts located at?

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.

Where on the earth are you most likely to find deserts?

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. Remember that moist, hot air always rises from the equator.

Why are most of Earth’s deserts located?

Due to the global pattern of air circulation and the relation to the atmosphere, most deserts are found within a belt centered on the 30° North and 30° South latitude lines. These regions are characterized by having a great deal of sunlight, minimal rain and high levels of evaporation.

Are deserts located near the Equator?

(Deserts do not occur near the Equator, tropics occur there). Higher in the atmosphere, the now cold, dry air rises and moves away from the equator. … As it warms, the air expands, condensation and precipitation are infrequent. (Horse latitudes).

Why are deserts not found on the equator?

(Deserts do not occur near the Equator, tropics occur there). Higher in the atmosphere, the now cold, dry air rises and moves away from the equator. At about 30 degree latitudes in both hemispheres (north and south), the air descends. … As it warms, the air expands, condensation and precipitation are infrequent.

Where are coastal deserts usually found?

Coastal deserts generally are found on the western edges of continents near the Tropics of Cancer and Capricorn. They are affected by cold ocean currents that parallel the coast. Because local wind systems dominate the trade winds, these deserts are less stable than other deserts.

Where is the desert located in India?

Why are deserts located in western margins of 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.

Where are hot deserts in the northern hemisphere mainly found?

Major hot deserts in northern hemisphere are located between 20-30 degree north and on the western side of the continents. Why? The hot deserts lie along the Horse Latitudes or the Sub-Tropical High Pressure Belts where the air is descending, a condition least favorable for precipitation of any kind to take place.

Why does it not rain in the desert?

Humidity—water vapor in the air—is near zero in most deserts. Light rains often evaporate in the dry air, never reaching the ground. Rainstorms sometimes come as violent cloudbursts. A cloudburst may bring as much as 25 centimeters (10 inches) of rain in a single hour—the only rain the desert gets all year.

The four main types of desert include hot and dry deserts, semi-arid deserts, coastal deserts, and cold deserts. In hot and dry deserts, also known as arid deserts, the temperatures are warm and dry year-round.

How are deserts formed on Earth?

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.
