Why deserts are generally found at western coast 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 for the air to hold moisture. Some deserts form in the rain shadow of mountains, eg the Atacama Desert is located in the rain shadow of the Andes.
Why most of the deserts are in Western Region Class 9?
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 deserts mostly found Why?
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 for the air to hold moisture.
Why major hot deserts of the world are located on the western margins of the continents between 15 30o north and south latitudes?
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.
How are deserts formed Upsc?
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.
Why are most of Earth’s deserts located in the subtropical zone?
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 is the West so dry?
Three main factors contribute to the natural phenomenon of drought: snowpack, soil moisture and temperatures. The Western states depend on snowpack for a good portion of their water supply. And right now, the soil across the region is exceptionally dry.
Where is the desert located in India?
Thar Desert, also called Great Indian Desert, arid region of rolling sand hills on the Indian subcontinent. It is located partly in Rajasthan state, northwestern India, and partly in Punjab and Sindh (Sind) provinces, eastern Pakistan. Thar (Great Indian) Desert. Encyclopædia Britannica, Inc.
Why do deserts occur?
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.
Why do the hot deserts of the world receives low rainfall?
The hot deserts receive less than 25 cm of annual rainfall, on the average, but many places do not get even this because the hot deserts are located on western margins of continents and in the belt of Trade Winds. Hence the winds get warmed up and the possibility of rainfall is reduced.
Why are hot deserts located 30 degrees north and south?
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.
Why are most deserts located on the western sides of continents?
Nature Environment Geography Geology General Topics We observe that most of the deserts are on the western sides of the continents in the subtropics. These are the results of the prevailing easterly winds of the tropics, which are the trade winds.
How was the desert formed?
1. Offshore areas of trade wind and falling under the rain shadow area: When the moisture laden trade wind flows from east to west shed their moisture on the eastern part and by the time they reach the western margin, they become dry. These dry winds make the soil more and this led to the formation of the desert.
What are the driest deserts on Earth?
Some of the driest deserts on Earth occur in the western side of continents and they are called Coastal Deserts. Examples of such deserts are the Atacama desert (Chile, the driest desert on Earth), the Baja California desert (USA/Mexico), the Namibia desert (southwestern Africa), and the Atlantic coastal desert of Morocco/western Sahara/Mauritania.
How many types of deserts are there in the world?
There are four types of desert found in the world: sub-tropical desert; Coastal deserts; Cold desert; Polar Desert. The fifth part of the Earth’s surface is desert.
