Hot Desert. This biome is mostly located between 15 ° and 35 ° latitude. They are distributed in Africa, North America, Middle East and Asia. These deserts mostly form behind mountains because of the relief rainfall. This is where the water gets pushed up a mountain and cools. This forms clouds and it rains, but not behind the mountain.
What is the distribution of desert?
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.
What is the global distribution of the desert?
Answer and Explanation: The global distribution of the desert biome is roughly 30 degrees of latitude north and south from the equator. These deserts occur here as the hot air that rises at the equator descends at this point due to global circulation patterns.
Where are hot desert climates found?
Hot desert climates are found across vast areas of North Africa, Western Asia, northwestern parts of the Indian Subcontinent, interior Australia, and smaller areas of the Southwestern United States, and Chile.
Where are deserts mostly located?
Although most deserts, such as the Sahara of North Africa and the deserts of the southwestern U.S., Mexico, and Australia, occur at low latitudes, another kind of desert, cold deserts, occur in the basin and range area of Utah and Nevada and in parts of western Asia.
What controls the distribution of the major desert regions of 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 most hot deserts are found on the western side of continents?
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.
What is the climate of hot deserts?
The climate is very dry with less than 250 mm of rainfall a year. Hot deserts have two distinct seasons: summer, when the temperature ranges between 35-40°C, and winter, when the temperature ranges between 20-30°C.
What is the 2 hottest desert in the world?

Why are hot deserts found in 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.
What is hottest desert in the world?
The Sahara is the hottest desert in the world – with one of the harshest climates. The average annual temperature is 30°C, whilst the hottest temperature ever recorded was 58°C. The area receives little rainfall, in fact, half of the Sahara Desert receives less than 1 inch of rain every year.
What country has the most desert?
China has the highest number of deserts (13), followed by Pakistan (11) and Kazakhstan (10).
Why most of the world deserts are located?
Most of the world's 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 most of the world's deserts located?
Most of the world's 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.
Is the desert diverse?
Diversity. Desert species diversity is very much dependent on rainfall and vegetative cover, with the fewest plant and animal species in the driest deserts. The Sonoran Desert is especially rich in species, with a substantial variety of distinct plant associations.
What is the climate like in the desert?
Summers in the desert are generally hot and dry. The average highest temperature is in the upper 90s Fahrenheit, and temperatures of more than 100 are common. The average lowest temperature, on the other hand, sits in the middle 60s Fahrenheit. In some years, the temperature drops to the 40s.
What is the climate in the desert biome?
During the day, desert temperatures rise to an average of 38°C (a little over 100°F). At night, desert temperatures fall to an average of -3.9°C (about 25°F). At night, desert temperatures fall to an average of -3.9 degrees celsius (about 25 degrees fahrenheit).
Where can deserts form?
Deserts can form even on tropical coasts beside cold ocean currents, such as the west coast of South America. The currents cool the air, which then rises and warms as it moves over land, drawing up moisture that is later precipitated as the air moves farther inland.
Where does the sun's radiation come from?
Hot air rises at the equator, where the land receives the greatest amount of the sun's radiation. 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.
How hot is the desert?
Climate of the hot desert. Climate is extremely hot and temperature remains more than 40 degrees for most time of the day. However, the hot desert become cold as the temperature falls below 0 degree. Climate is very dry with negligible humidity. The average rainfall is 250 mm a year.
What is the climate of the desert?

Why is desertification bad?
Desertification is probably the biggest problem in the desert because it involves land degrading, meaning that it becomes less productive.
What are some examples of ecosystems in the desert?
But, ecosystems in the desert have a lot of different things to content with. For example, the amount of rain that falls in a hot desert is very low. This means that animals have to keep moving to find water, or they have to be adapted to cope with very little water.
What are the factors that contribute to desertification?
One of the key aspects of desertification is soil erosion. This means that soil can easily be removed in layers by gusts of wind and water. This leads to nutrients being lost and soil becoming less productive quickly, making it difficult to grow anything on it.
What is the largest desert in the world?
World’s largest hot desert is Sahara which covers almost the whole continent. With an extreme climate hot deserts have very challenging environment for living beings. You will hardly any kind of vegetation there. Only few plants and animals have adapted to live in this climate.
How can we reduce the risk of desertification?
There are plenty of different things that can be done to reduce the risk of desertification, they include: By planting trees, people can prevent soil erosion. This is because the trees will act as windbreaks and prevent the wind from blowing away the top level of soil.

What type of climate is the hot desert?
The vegetation of hot desert climate is of xerophytic type which has special characteristics to withstand harsh climate characterized by extreme aridity, high temperature and very high rate of evaporation.
How are the winds and pressures of the hot desert affected?
Pressure and Winds of Hot Desert Climate: Poleward areas of the regions of hot desert climate are affected by divergent air circulation and anticyclonic conditions because they fall in the belt of subtropical high pressure.
