What is a Desert?

Characteristics of a Desert

A desert is a geographic region that is characterized by a limited amount of precipitation, high evaporation rates, extreme temperatures, and limited vegetation.

  • Limited precipitation: Deserts are known for their lack of rainfall, with many areas receiving less than 250 millimeters (10 inches) of precipitation per year. This lack of water makes it difficult for plants and animals to survive in these harsh environments.
  • High evaporation rates: Despite the limited amount of precipitation, deserts have high evaporation rates due to the high temperatures. This creates a strong atmospheric gradient, which drives the formation of sand dunes and other desert landforms.
  • Extreme temperatures: Deserts are known for their extreme temperatures, with daytime highs often exceeding 40°C (104°F) and nighttime lows dropping below freezing. These extreme temperatures make it difficult for plants and animals to survive, and they require special adaptations to survive in these harsh environments.
  • Limited vegetation: Due to the limited amount of water, deserts have limited vegetation. Some plants, such as cacti and succulents, have developed special adaptations to survive in these harsh environments, including the ability to store water and reduce evaporation. Other plants, such as shrubs and grasses, are limited to areas where there is more rainfall and more favorable growing conditions.
