Geology does not cause soil degradation. Geology describes land forms and layers of rock and other materials. As you dig down you find different layers of soil. Wind, rain, and running water have less difficulty washing away some layers than others. As a result, the way land will erode depends on the underlying geology. If there is a layer of dirt, it will wash away or blow away easier than a layer of solid rock. In the 1930's, some idiot in the United States Department of Agriculture decided that the Great Plains should be changed from grazing land to farm land. That changed grass land to dirt. When high winds came, they blew dirt all the way to the Atlantic Ocean. Wind blows dirt. The wind did not blow the grass. The geology did not cause the soil degradation, the wind did as did the idiots in the Agriculture Department. Grass had prevented the soil degradation for thousands of years.

What are the causes of degradation of soil?
Human activity is the main cause of soil degradation. Agriculture plays a large part in soil degradation, especially clearing, irrigation, the spreading of chemical fertilizers and pesticides, overgrazing and even the passage of heavy farming equipment. Tillage and the clearing and deforestation of large plots of land also lead to soil degradation. Improper drainage in agricultural fields also contributes to soil degradation.
What human activities cause soil erosion?
there are many human activities which cause soil erosion here is one of them; deforestation: cutting down of trees on large scale cause the degradation of soil because when rain comes and there are trees trees do not allow soil to move from its place .
What are 4 major causes of soil degradation?
Soil erosion and depletion are the major threats to soil as a resource. Both human and natural factors can lead to degradation of soils . Factors which lead to soil degradation are deforestation, overgrazing, overuse of chemical fertilisers or pesticides, rain wash, landslides and floods.
What is the difference between land degradation and soil erosion?
Land degradation is the land that is being degraded in some form that is negative. Soil erosion is when rock and soil is removed from one location of land to another.
Definition of soil degradation?
Soil degradation is when soil deteriorates because of human activity and loses its quality and productivity. It happens when soil loses its nutrients, or its organic matter. It also happens when the soil structure breaks down, or if the soil becomes toxic from pollution. The primary cause of soil degradation is erosion, but compaction, salinization, and depletion by nutrient demanding crops may also cause degradation. Soil degradation is which the movement of soil particles from one place to another by wind or water, is considered to be a major environmental problem. Erosion has been going on through most of earth's history and has produced river valleys and shaped hills and mountains. Such erosion is generally slow, but the action of man has caused a rapid increase in the rate at which soil is eroded (ie. a rate faster than natural weathering of bedrock can produce new soil). This has resulted in a loss of productive soil from crop and grazing land, as well as layers of infertile soils being deposited on formerly fertile crop lands; the formation of gullies; siltation of lakes and streams; and land slips. Man has the capacity for major destruction of our landscape and soil resources. Hopefully he also has the ability to prevent and overcome these problems.

What is the principal cause of soil degradation along the Murray River?
The principal cause of soil degradation along the Murray River is improper land use. Certain agricultural practices cause erosion, whilst over-iriigating causes increased salinity.

What is responsible for most soil degradation in the prairies of the United states?
Heavy rains are responsible for most soil degradation in the prairies of the United states. There are not enough plants to keep the soil in place.
