because the land is so dry that it can not absorb all of the water. Therefore causing erosion.
Inactive volcanoes are especially prone to erosion in areas were rainfall is plentiful. This reclamation of the area by local flora can lessen the effect.
Rainfall is least likely to occur in desert regions such as the Sahara Desert, Atacama Desert, or Antarctica due to the arid conditions in these areas. These regions receive minimal precipitation throughout the year, leading to a scarcity of rainfall.
People may choose to live in areas with moderate rainfall because it provides a balance wherein they can enjoy the benefits of rain without being overwhelmed by issues such as flooding or erosion that may occur in areas with heavy rainfall. Moderate rainfall regions also tend to be more conducive for agriculture and development, offering a better quality of life overall.
Groundwater is most effective in eroding soluble rocks like limestone, where it dissolves and carries away materials easily. Areas with high concentrations of limestone, such as karst landscapes, are particularly prone to groundwater erosion. Additionally, areas with abundant underground water flow or heavy precipitation can also experience significant erosion from groundwater.
Lack of rain prevents chemical erosion in a dessert.
Erosion after rainfall is a concern in desert areas because desert soils are typically dry and lacking in vegetation, making them more susceptible to erosion. Rainfall can cause flash flooding and wash away topsoil, leading to reduced soil fertility, loss of nutrients, and increased desertification in these fragile ecosystems.
The greatest agent of erosion is water which is rare in the desert except during the brief rainy season. Therefore, water erosion in the desert is much slower than in areas with more rainfall.
Parts of the Atacama Desert have received no measurable rainfall in historic time.
Erosion is worse when farms are in areas with high rainfall or severe drought.
Most areas of the desert receive little rainfall, just a few millimeters of precipitation. Some areas have received absolutely no rainfall in over 400 years.
By winds
Parts of the Atacama Desert have not recorded any rainfall in historic times.
If a desert has not been receiving normal rainfall, it is included in drought areas. If rainfall is normal or above, it would not be included.
Antarctica.. a desert is defined by how much rainfall it receives. Although it is made of ice, Antarctica has almost no rainfall per year, some areas have had NO rainfall for thousands of years, so technically, the continent is a desert.
Running Water
Areas that receive over 400 cm of rainfall are rain forests. The areas that receive less than 20 cm of rainfall are desert areas.
Lowest rainfall is observed in two desert areas of Pakistan i.e. Thar Desert and Cholistan Desert. These two areas witness one or two rains per year. People living in these areas store water in open ponds when rain hits these areas. People of these deserts use the stored water for the whole year.
