Why are deserts hotter in summer?

Answer 1

Not all deserts are hot. The Gobi Desert in Asia is an example of a desert with cool or cold areas. The term "Desert" does not refer to the average temperature of this biome; it refers to the lack of water and limited precipitation it receives.

Answer 2

Deserts are hot primarily because of the lack of water. When the sun shines on the ground, all of the absorbed sunlight goes into raising the ground's temperature. If there was moisture in the soil, much of this heat would go into evaporation of some of the water, pumping water vapor in the air, and keeping the soil cooler that it would otherwise be. This cooling is from the "latent" heat of evaporation that is required to change liquid water into water vapor. Associated with the lack of water is a lack of vegetation, which also evaporates water as part of photosynthesis -- a process called evapotranspiration. The vegetation itself doesn't cool the desert -- it's the water being processed by the vegetation. In fact, since vegetation is darker than most desert soils, if a desert could have vegetation that didn't need water to live, the desert would actually be hotter since it would absorb more sunlight! Similarly, if deserts were covered by dark soil rather than light soil or sand, they would also be hotter. The common view that deserts are so hot because of the bright sand is, therefore, incorrect.

Answer 3

The reason why deserts become so hot is because there is prevailing hot wind blowing to the deserts which make the deserts air hott aswell!The reason why deserts become so hot is because there is prevailing hot wind blowing to the deserts which make the deserts air hott aswell!

Answer 4

Not all deserts are hot. Some deserts are cold, such as Antarctica and the Patagonian Desert. Some are cool such as the Atacama and Sechura Deserts. Some deserts are hot in the summer but cold in the winter such as the Great Basin and Gobi. Others are hot in the summer and cool in winter - Sahara, Mojave and Sonoran Deserts.

Answer 5

Not all deserts are hot. In fact, there is more area of the earth covered by cold deserts than by hot deserts. Antarctica is a true desert and the temperature can plunge to below -100 degrees F at times and some areas never exceed the freezing point. The Patagonian Desert, Monte Desert and Atacama Deserts are always cool, sometimes uncomfortably chilly, even in the summer months.

Answer 6

Not all deserts are hot. There are hot deserts. There are cold deserts and there are cool deserts. Geography determines if a desert is hot or cold.

Answer 7

Deserts are not all hot, there are some cold (very cold) deserts such as Antarctica.

Answer 8

In hot deserts the sun is almost directly overhead in the summer so the area receives intense solar radiation which cause the soil and air to get quite hot.
