A climate characterized by very little rainfall is referred to as a desert climate or arid climate. Deserts typically receive less than 10 inches (25 centimeters) of precipitation annually, leading to dry conditions and sparse vegetation. The temperatures in deserts can vary widely, with some areas experiencing extreme heat during the day and chilly nights. The lack of rainfall limits the types of flora and fauna that can thrive in these environments, resulting in unique adaptations for survival. Notable deserts include the Sahara in Africa and the Mojave in North America.
