Abiotic Factors
Abiotic factors in biology are non-living chemical and physical factor that influence environment, for example soil, pH, and temperature.
There are many different abiotic factors for the desert and the reason why is because there are different types of desert around the the world such as hot and dry, semiarid desert, coastal desert, and cold desert.

Hot and dry - Are and located in Chihuahua, Sonora, Mojave and Great Basin in United States. In other counties are southern Asia realm, Neotropical in South and Central America, Ethiopian in Africa and lastly Australia. Hot and dry have seasons in general warm throughout the year and very hot in the summer. For the winter usually bring little rainfall. The temperatures exhibit daily extremes because the atmosphere contains little humidity to block the sun’s rays. In the annual temperatures ranges are from 20-25° C and the extreme maximum range are from 43.5-49° C. Rainfall is usually very low or concentrated in short bursts between long rainless periods. At times the rain starts falling and evaporates before reaching the ground. Soils are curse-textured, shallow, rocky or gravely with a good drainage with no subsurface water. The reason why they are coarse because is less chemical weathering.
Semiarid desert are located in North America, New found, Greenland, Russia, Europe, and northern Asia. In the summers are moderately long and dry and are like hot desert, as for the winter normally brings low concentrations of rainfall. In the semiarid desert the temperature is an average between 21-27° C. In the evening are cool around 10° C and in cool nights help both plants and animals by reducing moisture loss from transpiration, sweating and breathing. The soil is from sandy and fine-textured to loose rock fragments, gravel or sand. Semiarid desert has a fairly low salt concentration compared to desert which means this certain desert receive low amounts of rain.
Coastal desert – is a desert that is moderately cool to warm areas such as Atacama,Chile. Coastal desert winters are cool winters that are followed by moderately long, warm summers. Summer temperature ranges from 13-24° C and winter temperature are 5 °c below. The soil is fine-textured with a moderate salt content. It has a fairly porous with good drainage and some plants have extensive root system close to the surface where they can take advantage of any rain showers.
Cold desert - are deserts that have cold winters with snowfall and high overall rainfall throughout the winter and over the summer occasionally. Cold desert have short, moist, and moderately warm summers with fairly long, cold winters. The winter temperature is between -2-4C and the summer’s temperature is between 21-26° C.
