Jared-desert

a desert is an area where little or no life exists because of the lack of water. Scientist estimate that deserts cover about 1/5 of the world's surface. Deserts are found in every continent besides Europe. Four major deserts in the US are the Great Basin, Mojave, the Sonoran, and the Chihuahuan. With the lack of heat and extreme heat or cold make this place inhospitable to most life forms. Most plants you'll see are related to cacti. Only a few mammals-mainly reptiles and lizards-that have adapted to this environment. The Arctic and Antarctica are called deserts cause of the lack of water and extreme cold. Mammals include the Emperor Penguin and the Adelie Penguin, these live in Antarctica. Polar bears live in the Arctic. So polar bears and penguins never see each other, unless they're in a zoo.

Drought-Happens when the average rainfall drops far below the normal amount for a long period of time Flashfloods-Sudden rain upstream cause these, more people die in flash floods than they do die of thirst Dry and arid, From sand to flat deserts of rock, Most are far away from coast lines

Soils are coarse or gravelly with good drainage and have no subsurface water The soil is coarse because there is less chemical weathering. The finer and smaller grains are blown away. Did you know that sand only covers 20% of a desert? [] [] http://www.factmonster.com/ipka/A0769052.html
