Desert Soil Type and Geographic Features-32° 15′ 36″ N, 112° 55′ 34″ W

The soil of deserts are course, shallow, rocky, and very nutrient because all they need is water to be productive. There is little to no organic matter within the soil of deserts. The soil type allows good drainage when it does rain and there is no subsurface water.

One geographic condition that affects the desert biome are mountains. Mountains cause rain shadow deserts by blocking rain from the deserts. Another geographic condition affecting deserts are cold water upwells along a cost. These stabilize the air and also prevent mosture from foming, therefore creating a cool coastal desert.
