Would you rather stay out in the hot desert sun or the cold desert night? You know that deserts are usually hot and dry. They can have a wide range of temperature changes. With some low precipitation. Sometimes they can lose moisture.
Did you know that deserts aren't made up of sand? They are made up of rocks and gravel. The animals that live in the desert actually preserve body moisture to adapt to the hot weather. That's why we don't live in the desert.
