Deserts in the southwest region of the United States are very dry and extremely hot. Deserts such as the Sonoran desert, Mojave desert, the Great Basin desert, and the Chihuahuan desert (even though 2 stretch into Mexico) are all in this particular area. There is very little plant life, mostly sand and dry rocks. Only sparse patches of green vegetation and cacti appear. There is a large range of wildlife there occupying this seemingly barren place.
