The climate in a desert is characterized by extreme temperatures and minimal precipitation, typically receiving less than 250 millimeters (10 inches) of rain per year. Deserts can experience scorching daytime temperatures, often exceeding 40°C (104°F), while nighttime temperatures may drop significantly due to a lack of cloud cover. The low humidity and high evaporation rate contribute to the arid conditions. Vegetation in deserts is sparse, consisting of various drought-resistant plants, while wildlife has adapted to survive with limited water resources. Deserts can be hot, like the Sahara, or cold, like the Antarctic Desert, highlighting their diversity.
