Individual Assignment Cheyanna Ruttschaw EVS 1001-11 Everest Online There are three major causes of soil erosion: overgrazing‚ over cultivation‚ and deforestation. Together‚ these three problems cause more problems by creating unsustainable societies. Luckily‚ overgrazing‚ over cultivation‚ and deforestation can be fixed and the unsustainable society becomes a sustainable one. Overgrazing is when there are more animals in comparison to land‚ meaning that there isn’t as much food for the

is gully erosion? Gully erosion is the removal of soil along drainage lines by surface water runoff. Once started‚ gullies will continue to move by headward erosion or by slumping of the side walls unless steps are taken to stabilise the disturbance. Repair work done in the early stages of newly formed gullies is easier and more economical than letting the problem go unchecked for too long. Large gullies are difficult and costly to repair. What causes gully erosion ? Gully erosion occurs when

the buildings reduce the beaches ad many construction sites extract coastal sand for their projects. The coastal erosion that affects my hotel are both natural and anthropogenic. The slow rise of the sea level is gradual and takes time to happen‚ but this region is impacted by hurricanes and tropical storms which cause a severe costal erosion in short time. Many efforts to combat erosion‚ such as sand fill‚ are defeated by severe weather systems. As we have seen on all natural processes‚ there is balance

Soil erosion Soil erosion occurs when soil is removed through the action of wind and water at a greater rate than it is formed SOIL The soil covering the surface of the earth has taken millions of years to form and we must learn to respect it. Soil is formed at a rate of only 1 cm every 100 to 400 years and it takes 3 000 to 12 000 years to build enough soil to form productive land. This means that soil is a nonrenewable resource and once destroyed it is gone forever. If we disregard this‚ a

Coastal Erosion Coastal erosion is a naturally occurring phenomenon resulting from the continuous action of wind and water. Both act to remove small pieces of land from one location and deposit them elsewhere. Weather events such as hurricanes and nor’easters speed the erosion process‚ as do tidal waves. Currently‚ rising sea levels resulting from melting polar ice decrease available land as well. While erosion has always been a factor of coastal living‚ increasing populations along the worlds

What is soil erosion? Soil erosion is a natural process‚ occurring over geological time‚ and indeed it is a process that is essential for soil formation in the first place. With respect to soil degradation‚ most concerns about erosion are related to accelerated erosion‚ where the natural rate has been significantly increased mostly by human activity. Soil erosion by water is a widespread problem throughout Europe. Soil is naturally removed by the action of water or wind: such ’background’

Soil Erosion Erosion is a natural process by which rock and soil are broken loose from the earth’s surface at one location and moved to another. Soil erosion forms and changes land by wearing down mountains filling valleys‚ and making rivers appear and disappear. Erosion is usually a slow and gradual process that occurs over the course of thousands or millions of years. However the rate of erosion can be speeded up by such human activities as mining. How erosion occurs? Ero0sion begins with

when the fertility of the soil is seriously reduced‚ the people again change their land of cultivation. Thus the essential feature of shifting cultivation is the rotation of fields rather than crops. As a result more and more land are exposed to erosion.
