How would you describe a desert environment?

Desert environments are so dry that they support only extremely sparse vegetation; trees are usually absent and, under normal climatic conditions, shrubs or herbaceous plants provide only very incomplete ground cover.

What are the characteristics of desert?

Deserts are characterized by low humidity (air moisture), low annual rainfall, and an overall moisture deficit, meaning the rate of evaporation exceeds the rate of rainfall on average. Deserts are also characterized by extreme temperatures.
