They cover about one-fifth of the land surface and can be hot or cold, depending on their location and climate. Deserts are characterized by extreme temperatures, low humidity, sparse vegetation, and high evaporation rates. Deserts are not lifeless wastelands, however. They are home to a variety of plants and animals that have been attuned to the harsh conditions. Some of these specializations include drought tolerance, water conservation, heat tolerance, camouflage, and nocturnal activity. Deserts also have unique geological features, such as sand dunes, salt flats, oases, and rock formations. Deserts are important for many reasons. They provide natural resources, such as minerals, oil, and solar energy. They also influence the global climate by reflecting solar radiation and creating wind patterns. Deserts are also rich in cultural diversity and history, as many civilizations have e
