The world's largest non-polar deserts. Deserts occupy about one third of Earth's land surface. [6] Bottomlands may be salt -covered flats. Eolian processes are major factors in shaping desert landscapes. Polar deserts (also seen as "cold deserts") have similar features, except the main form of precipitation is snow rather than rain.
The Mojave Desert is a desert bordered to the west by the Sierra Nevada mountain range and the California montane chaparral and woodlands, and to the south and east by the Sonoran Desert. The boundaries to the east of the Mojave Desert are less distinctive than the other boundaries because there is no presence of an indicator species, such as ...
The desert climate or arid climate (in the Köppen climate classification BWh and BWk) is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive.
Desert ecology. Desert ecology is the study of interactions between both biotic and abiotic components of desert environments. A desert ecosystem is defined by interactions between organisms, the climate in which they live, and any other non-living influences on the habitat. Deserts are arid regions that are generally associated with warm ...
The Sahara (/ s ə ˈ h ɑːr ə /, / s ə ˈ h ær ə /) is a desert spanning across North Africa.With an area of 9,200,000 square kilometres (3,600,000 sq mi), it is the largest hot desert in the world and the third-largest desert overall, smaller only than the deserts of Antarctica and the northern Arctic.
Sodium nitrate forms through the evaporation of water in desert areas. The richest cache of sodium nitrate is located in South America; approximately 3 million metric tons were mined during World War I. It was the earliest food preservative, and is still used today to cure fish and meat to produce bacon, ham, sausage and deli meats.
The Arabian Desert has a subtropical, hot desert climate, similar to the climate of the Sahara Desert (the world's largest hot desert). The Arabian Desert is actually an extension of the Sahara Desert over the Arabian peninsula. The climate is mainly dry. Most areas get around 100 mm (3.9 in) of rain per year.
Oasis. The desert oasis city of Jubbah in Saudi Arabia as photographed from space. In ecology, an oasis (/ oʊˈeɪsɪs /; pl.: oases / oʊˈeɪsiːz /) is a fertile area of a desert or semi-desert environment [1] that sustains plant life and provides habitat for animals. Surface water may be present, or water may only be accessible from wells ...
