Detailed explanation-1: -Deserts are arid ecosystems that receive fewer than 25 centimeters (10 inches) of precipitation a year. Death Valley, California, above, receives fewer than 5 centimeters (2 inches) of rainfall every year. However, Death Valley’s infrequent rain and extreme temperatures can impact the landscape.

Detailed explanation-2: -In hot and dry deserts, also known as arid deserts, the temperatures are warm and dry year-round. Some famous arid deserts include the Sahara Desert that covers much of the African continent and the Mojave Desert located in the southwest of the United States. Semi-arid deserts are a bit cooler than hot and dry deserts.

Detailed explanation-3: -Deserts are barren areas of land characterised by extremely high or low temperatures, with low rainfall and scarce or no vegetation. Deserts are examples of terrestrial ecosystems, which are found throughout the world.

Detailed explanation-4: -Temperature. During the day, desert temperatures rise to an average of 38°C (a little over 100°F). At night, desert temperatures fall to an average of-3.9°C (about 25°F). At night, desert temperatures fall to an average of-3.9 degrees celsius (about 25 degrees fahrenheit).

Detailed explanation-5: -There are four types of deserts: subtropical deserts are hot and dry year-round; coastal deserts have cool winters and warm summers; cold winter deserts have long, dry summers and low rainfall in the winter; polar deserts are cold year-round.
