Deserts are areas of the world that are extremely dry. They don't get much rain. Officially a desert is an area that gets less than 10 inches of precipitation (降雨) a year. Deserts don't necessarily have to be hot. Some of the world's largest deserts are cold deserts located at one...

among those who agree upon this classification, there is disagreement over the exact geographic areas circumscribed by each of the four deserts. Some scientists would use animals and other criteria, as well as distribution of plant species, to determine desert different boundaries for these four ...
variations produced by this rugged surface, and the opportunities for runoff—and in a few places surface accumulation—of rainwater, are important in providing localized habitats for plants and animals. Large areas of loose, mobile sand provide the harshest and poorest of the major deserthabitat...

In many regions of the world a combination of climatic factors and human activities are believed to be causing desertification. Regions at risk have the longest history of agriculture—from North Africa to China—and large areas of Australia and central North America. Paleo-deserts, large sandy ma...
