What Is a Desert?


Deserts are arid regions where there is little or no precipitation. These environments support specialized types of vegetation. Animals found in these environments include small nocturnal carnivores, such as kangaroo rats. They also include insects, arachnids, and reptiles. They feed mainly at dusk and dawn. The Great Basin and the sagebrush deserts of the West are examples of deserts of this type.


Deserts are climates where precipitation is low or absent. In some places, deserts may go years without rain. For example, the Cochones Desert in Chile had no rain for 45 years between 1919 and 1964. In other places, rain can fall heavily for short periods. The Israeli city of Mashabe Sade, for instance, received 14 millimetres of rain in seven minutes on October 5, 1979.

They are arid

Deserts are areas that lack rainfall and are often characterized by large expanses of bare soil. They also have few high-intensity rainfall events. As a result, arid soils undergo physical and chemical processes that alter their hydraulic properties. These changes are reflected in the formation of a hard layer on the surface of the soil. The desert crust is often rich in calcite.

They receive little precipitation

Deserts are areas of the earth that receive very little precipitation. These areas can be rich in fossils and valuable mineral deposits. The climate of a desert is typically hot during the day and cold at night. This is due to the fact that the air is very dry and retains very little heat. The absence of cloud cover also helps to release heat more readily at night.

They have specialized vegetation

Deserts are biomes that have specialized vegetation and animals. They are often found in dry and arid regions and are characterized by very low temperatures, little precipitation, short growing seasons, and specialized photosynthetic processes.

They have specialized animals

Deserts are a place where many animals live, some of which have evolved to withstand the dry climate. Camels and wild asses are two examples of animals that can survive in such environments. These animals have long limbs and ears, which act as radiators in the desert heat and help them to stay cool. Some animals also have specialized kidneys, which are capable of producing water from their food.

They are hard to live in

Deserts are harsh environments that are very hard for humans to survive. Not only are they inhospitable to humans, but plants and animals can’t survive there either. They also have extremely low humidity and fluctuating temperatures, making them extremely hard to survive. Whether it’s Antarctica or the Sahara Desert, these conditions can make living in a desert difficult, if not impossible.
