Very little further erosion takes place after the formation of a pavement, and the ground becomes stable. The Sahara Desert is expanding at the rate of around 30 miles per year. [83] The kangaroo rat for example makes use of this water of metabolism and conserves water both by having a low basal metabolic rate and by remaining underground during the heat of the day,[84] reducing loss of water through its skin and respiratory system when at rest. They form perpendicular to the wind direction and gradually move across the surface as the wind continues to blow. The range of temperatures on a daily and annual scale is relatively low, being 11 °C (20 °F) and 5 °C (9 °F) respectively in the Atacama Desert.

Many solar power plants have been built in the Mojave Desert such as the Solar Energy Generating Systems and Ivanpah Solar Power Facility. These areas exist under a “moisture deficit,” which means they can frequently lose more moisture through evaporation than they receive from annual precipitation. Despite the common conceptions of deserts as hot, there are cold deserts as well. Ideal war fields! Product information not available. Flies, beetles, ants, termites, locusts, millipedes, scorpions and spiders[96] have hard cuticles which are impervious to water and many of them lay their eggs underground and their young develop away from the temperature extremes at the surface. 30 Interesting Facts About The Sahara Desert Located in the northern part of Africa, the Sahara is the world's largest hot desert; covering an area of more than 9 million square km.

The Chihuahuan and Sonoran Deserts encompass portions of the southwestern United States and Northern Mexico. Some annual plants germinate, bloom and die in the course of a few weeks after rainfall, while other long-lived plants survive for years and have deep root systems able to tap underground moisture.

Most shrubs have spiny leaves and shed them in the coldest part of the year. In northern China, growing urbanization, which left much of the land unprotected against wind erosion and the buildup of sediment from the surrounding desert, created a desertification problem, prompting the government to build a "great green wall" as a hedge against encroaching desert. It is because the temperature is hot at day and cool at night. [63][64] Nevertheless, there is some plant life in the Atacama, in the form of specialist plants that obtain moisture from dew and the fogs that blow in from the Pacific.

Sure, our planet looks like a watery blue marble from space, but one-third of Earth's land surface is partially or totally desert. The water budget of an area can be calculated using the formula P − PE ± S, wherein P is precipitation, PE is potential evapotranspiration rates and S is the amount of surface storage of water. [108], Round the rims of deserts, where more precipitation occurred and conditions were more suitable, some groups took to cultivating crops. [79], Deserts present a very challenging environment for animals. This book gives a broad survey on some of the affected regions of the world as well as some case studies from elsewhere (Aral Sea, Negev desert, Namib desert etc.).

The desert biome is the characteristic community of animals and plants found in the world's deserts. The world's deserts are harsh, inhospitable places. Rain falling in the cold season may be more effective at promoting plant growth, and defining the boundaries of deserts and the semiarid regions that surround them on the grounds of precipitation alone is problematic.[17]. [17], Cold deserts, sometimes known as temperate deserts, occur at higher latitudes than hot deserts, and the aridity is caused by the dryness of the air. Birds have avoided the problem of losing heat through their feet by not attempting to maintain them at the same temperature as the rest of their bodies, a form of adaptive insulation. [71], Many desert plants have reduced the size of their leaves or abandoned them altogether. The Desert Biome - DesertUSA - Magazine about the American Southwest.

The plant and animal life in the area is very hostile due to the little amount of precipitation. Yet more than one billion people, one-sixth of the Earth's population, actually live in desert regions. Evaporation can concentrate minerals as a variety of evaporite deposits, including gypsum, sodium nitrate, sodium chloride and borates. [102] Evaporites are found in the USA's Great Basin Desert, historically exploited by the "20-mule teams" pulling carts of borax from Death Valley to the nearest railway. Most deserts get less than ten inches of precipitation each year and evaporation usually exceeds rainfall. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Once ejected, these particles move in one of three possible ways, depending on their size, shape and density; suspension, saltation or creep.

[34], As the mountains are eroded, more and more sand is created. It is situated in the Southwestern United States, primarily within southeastern California and southern Nevada. Deserts are renowned for being dry, extremely hot and often remote. Some mineral extraction also takes place in deserts, and the uninterrupted sunlight gives potential for the capture of large quantities of solar energy. Unlike most global deserts, the Antarctic covers the entire continent. Many locations within this category have elevations exceeding 3,000 m (9,800 ft) and the thermal regime can be hemiboreal. And deserts will expand towards communities as evaporation increases and dust storms multiply. [23] The Taklamakan Desert is an example, lying in the rain shadow of the Himalayas and receiving less than 38 mm (1.5 in) precipitation annually.

In the Sonoran Desert, Couch's spadefoot toad spends most of the year dormant in its burrow. Evapotranspiration is the combination of water loss through atmospheric evaporation and through the life processes of plants. The mechanism is little understood but the particles usually have a negative charge when their diameter is under 250 μm and a positive one when they are over 500 μm.[41][42]. [30] Chemical weathering processes probably play a more important role in deserts than was previously thought. Only about 20 percent of deserts are covered by sand. The term dessert can apply to many confections, such as . A place that receives less than 10 inches (25 centimeters) of rain per year is considered a desert.

[37] In a really severe steady blow, 2 m (6 ft 7 in) is about as high as the sand stream can rise as the largest sand grains do not become airborne at all. A study of these microbes found that desert farming hampers desertification by establishing islands of fertility allowing farmers to achieve increased yields despite the adverse environmental conditions. When they descend on the leeward side, they warm and their capacity to hold moisture increases so an area with relatively little precipitation occurs. African Aardvarks are living fossils not having changed for millions of years. All rights reserved, largest hot desert in the world, northern Africa's Sahara, some deserts are always cold, like the Gobi desert in Asia, about 20 percent of deserts are covered by sand, studied them for clues about life on Mars, known as desertification, is not caused by drought, deforestation and the demands of human populations, threatens to change the ecology of deserts. [51], The shape of the dune depends on the characteristics of the prevailing wind. It contains many mountains, the highest being Mount Al-Nabi Shu'ayb in Yemen at 3,760 m. This picks up particles of sand and dust, which can remain airborne for extended periods – sometimes causing the formation of sand storms or dust storms. [17], In 1961, Peveril Meigs divided desert regions on Earth into three categories according to the amount of precipitation they received. Some are superhot in the day. In the heat of the day in the Sahara, the temperature can rise to 50 °C (122 °F). This lack of water makes desert landscapes vulnerable.
