1. Pantagonian Desert, which is located primarily in Argentina with small parts of Chile and is bounded by the Andes,to its west, and the Atlantic Ocean to its east, in the region in Patagonia, southern Argentina. To the north the desert grades into the semi-arid Cuyo Region and the Dry and Humid Pampas.
2.The Atacama Desert of northern Chile is the World's second driest region. Although the Tropic of Capricorn passes through the region, the Atacama desert lies in the rain shadow of Chile's Coast Range, which squeezes out the moisture from the atmosphere.
3.The Sahara Desert is located in the northern portion of Africa and covers over 3,500,000 square miles (9,000,000 sq km) or roughly 10% of the continent. It is bounded in the east by the Red Sea and it stretches west to the Atlantic Ocean. To the north, the Sahara Desert's boundary is the Mediterranean Sea, while in the south it ends at the Sahel, an area where the desert landscape transforms into a semi-arid tropical savanna.
The desert is very fragile in many ways, because of the scarcity of water and plants. Most plants that live in the desert take a long time to grow. For example, the saguaro cactus takes two centuries to grow. Once plants are destroyed, it will take many years for them to grow back. Since soil in the desert is held down by the plant roots, once plants are destroyed the soil is too. The soil will quickly erode away in the strong winds. Additionally, many types of human activities negatively impact the desert. Such as off roading, when people drive their off road vehicles in the unrestricted areas all over the desert. Their vehicles leave tracks on the soil, which will scare the land for decades. These tracks also kill off vegetation, and when this is harmed so is the animal population. Plus animals that hide in the sand can be harmed such as the sand viper, that hides well in the soil and may become a victim of off roading destruction.
Animals found in the temperate desert consist of: argali, bighorn sheep, saiga antelope. Some carnivores: sand fox, cross fox, Chinese desert cat, jungle cat, wild cat, Eurasian lynx, Chilean pampa cat, cheetah, cougar, American jackal, Arctic wolf, Corsac fox. Bats: Botta's serotine, Namib long-eared bat. Rodents: cape short-eared gerbil, yellow steppe lemming, long-eared jerboa, namib brushed-tailed gerbil, dune hairy-footed gerbil, gerbil mouse, littledale's whistling rat, namaqua rock rat, gobi jerboa, pouched mouse, bucharian vole, thick-tailed pygmy jerboa, heptner's pygmy jerboa, Kozlov's pygmy jerboa, Five-toed pygmy jerboa,Thomas's pygmy jerboa, Cape gerbil,Highveld gerbil,Gray glimbing mouse. Also you can find: rock dassie, African elephants, pichi, screaming hairy armadillo, large hairy armadillo, lesser fairy armadillo. Producers/Plants found: Sagebrush, phreatophytes, succulents & parasites, tiny leaves, halophytes, grasses, and some roadside growth.
Deserts are areas where the rainfall is too low to sustain any vegetation at all, or only very scanty scrub. The rainfall in desert ares is less than 25 mm or 10 inches per year, and some years may vary experience no rainfall at all. The hot deserts are situated in the subtropical high pressure belts where there is unbroken sunshine for the whole year. Such areas include the Sahara, Saudi Arabia, large parts of Iran and Iraq, northwest India, California, South Africa and much of Australia. Here, Maximum temperatures of 40 to 45 degrees Celsius are common, although during colder periods of the year, night-time temperatures can drop to freezing or below due to the exceptional radiation loss under the skies.
Abiotic Characteristics: Cold deserts get more precipitation than dry ones b/c they get a lot of snow in the winter. The tempuratures get very cold during the winter.

-The desert biome has the lowest amount of productive compared to the rest.
-"temperate" means cold.
-Deserts cover 20% of the Earth's surface.
-People don't really know that deserts can be cold, for example the Atacama desert which reaches into Antarctica from Chile.
