Study Notes

Types of Desert Biomes

  • Hot and Dry: The most common desert type. Very hot (unlike freezing winters in tundra) and gets very little rain. Some don't see rain for years.

  • Coastal: Cool winters and long mild summers.

  • Cold: Cold all year, and receives all precipitation as snow.

  • Semi-arid: Cooler than hot and dry deserts.
