because the land is so dry that it can not absorb all of the water. Therefore causing erosion.
Groundwater erosion occurs most often in areas with an abundance of limestone and rainfall. This erosion can create large cavities and caves.
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.
A desert is sometimes defined as an area with a rainfall of less than 500mm a year, therefore New Zealand does not have any significant areas of true desert. Some small areas of inland Otago and Canterbury in the South Island do have this low an annual rainfall, but only just. Some reasons for the misconception that New Zealand has desert is the name for one of the State highways in the central North Island being the Desert Road and there is a region known as the Rangipo desert. It has a much higher rainfall than a desert, but has high winds and poor soils, so seems like a desert.
Lack of rain prevents chemical erosion in a dessert.
Rainfall in mountain areas is called: Orographic rainfall.
because the land is so dry that it can not absorb all of the water. Therefore causing erosion.
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.
Wind erosion, a type of erosion where wind blows away sediment, is common in desert areas.
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.
Groundwater erosion occurs most often in areas with an abundance of limestone and rainfall. This erosion can create large cavities and caves.
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.
