there are many types of desert. Hot and Cold air can dry water. Did you know that Antarctica is considered a desert? That's because it is hard to find fresh water there; water that isn't frozen. The Sonoran Desert is hot, which evaporates most water. Plants and animals that live there have to be able to resist heat. it can get very cold in the desert at night.
