satellite image of the Sahara Desert Why are deserts so hot? Deserts are hot primarily because of a 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, which requires heat to accomplish, and thus 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, and is the same reason why water evaporating from your skin feels cold.
Associated with the lack of water is a lack of vegetation, which would also cause water to evaporate as part of photosynthesis -- a process called evapotranspiration.
The common perception that deserts are hot because of the bright sand is incorrect. 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. Instead, the vegetation causes water to evaporate (and uses some of the sunlight for other plant growth process). Similarly, if deserts were covered by dark soil rather than light soil or sand, they would also be hotter. Interesting facts: DESERTS ARE COLD AT NIGHT:Because of the lack of water in the ground, and little water vapor in the air, most deserts can get quite cool at night. This is because (1) dry ground does not retain as much heat as moist ground, and (2) water vapor is the most important greenhouse gas, so dry air allows the surface to cool rapidly at night through loss of infrared radiation to outer space.
In fact, it has been calculated that the Sahara Desert actually loses more infrared radiation than it gains solar radiation from the sun. This net loss of radiant energy is balanced by the sinking air over the desert, which warms as it is compressed. The air over the desert is, in turn, being forced to sink by rising within rain systems hundreds or thousands of miles away. Thus, in some sense, rain can be considered the cause of deserts(!).
Rudyard Kipling was a British author. Born in Bombay, India he is best known for his work of fiction The Jungle Book. Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
Most immigrants to the United States in the antebellum era came from Germany and Ireland. There were various reasons why they emigrated into the States, but the most important one was civil unrest in their native countries. Also, they couldn't find jobs home, and they heard that America is a land of freedom and opportunity, so obviously they wanted to be successful too.
The answer is actually "The attack on the World Trade Center." on February 26, 1993, 6 people died, but hundreds of others were injured and sent to the hospital in critical conditions. More than a thousand people were injured that day. The World Trade Center itself suffered more than $500 million in damage. After the attack, authorities evacuated 50,000 people from the buildings.
