Abiotic Factors
Very dry with little rain, hot/tropical deserts get under 1 inch of rain a year. Deserts clear skies/atmosphere allow the suns rays to directly beat on the soil making it very hot. Clear skies account for the cool nights, because the stored heat radiates quickly in the night. Deserts are also very dry and hot because the soil/sand absorbs very little moisture. Most hot/tropical deserts are located in the Africa and the Middle East.
Hot and dry have seasons in general warm throughout the year and very hot in the summer. For the winter usually bring very little rainfall. The temperatures exhibit daily extremes because the atmospheres contains little humidity to block the sun's rays. The annual temperatures ranges are from 20 - 25degrees C and the extreme maximum range are from 43.5 - 49degrees C. Rainfall is usually very low or concentrated in short bursts between long rainless periods. At times the rain starts falling but evaporates before reaching the ground. Soils are curse-textured, shallow, rocky, or gravely with a good drainage, with no surface water. The reason why they are less coarse is chemical weathering.
Semiarid deserts in the summer are moderately long and dry and are like hot deserts as for the winter normally brings low concentrations of rainfall. In the Semiarid desert the temperature is an average between 21 - 27degrees C. The evenings are cool and the temperatures are around 10degrees C. and in cool nights help both plants and animals by reducing moisture loss from transpiration, sweating, and breathing.

The Cold desert gets 10 inches of snow a year, and it usually never rises above 50degrees F. in the summer.
Cold deserts are known as Polar Deserts, they are located throughout the planet. Although they exist around the world, they are usually located around the Artic region. All of these deserts are heavily covered in sand dunes and pebbles. There are occasional mountain ranges.
These deserts are known for their cold winters with snow fall and rain throughout the winter season and also summer. They have short, moist, and moderately warm summers with long, cold winters. The soil is heavy and full of salt. The growing season ranges from 50 to 60 days. The average winter temperature is -34degrees C., but the average summer temperature is 3 - 12degrees C. which enables the biome to sustain life. Rainfall may very in different regions of the arctic desert. Soil is formed slowly. A layer of permanently frozen subsoil called permafrost exists, consisting mostly of gravel and finer material. When water soaks the upper surface, bogs and ponds may form, providing moisture for plants.
