* Desert: Characterized by extremely low precipitation (less than 10 inches per year) and very high evaporation rates. Temperatures can vary greatly between day and night.

* Steppe: Also known as semi-arid climates. They receive slightly more precipitation than deserts (10-20 inches per year) and have a wider range of temperatures than deserts.
