Desert is a very dry region that receives little rainfall. Deserts can be hot or cold and may have sandy, rocky, or icy surfaces. Plant life is limited and adapted to dry conditions. Animals in deserts are also adapted to survive with little water.

Deserts are found on every continent, including the Sahara in Africa and Antarctica in the polar region. They exist as long-term climate regions. Some people live in desert areas and have adapted to the environment. Deserts are home to unique plants, animals, and ecosystems.
