Answers
Answer:
the characteristics of desert soils are sa following:
Desert soils are usually light colored
Desert soils have B horizons. Often the B horizons have accumulations of calcium carbonate (caliche), gypsum, and/or salts.
Desert soils have sparse vegetative cover that varies with temperature and elevation
Desert soils are highly variable: They may be deep, shallow, salty or covered with desert pavement, or have crusts or cement-like horizons near the surface.
Deserts cover 20 to 33% of the Earth’s land surface, and can be found in the tropics, at the poles, and in between.
Desert soils (Aridisols) occupy about 12% of the Earth’s ice-free land surface, and 8% of the United States, all in the western states: Texas, New Mexico, Colorado, Wyoming, Montana, Arizona, Utah, Nevada, Idaho, California, Oregon, and Washington.
