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

Beach erosion longstanding challenge for southeastern NC There is a major environmental concern in the southeastern region North Carolina; it is beach erosion. However do not worry‚ the article states “The good news is that we do have alternatives to help control erosion‚ but the bad news is that these alternatives can also have negative consequences.”. A method that is able to help control erosion is beach nourishment‚ although it is not a cure for beach erosion‚ but rather a treatment to help

The soils ability to grab and hold important nutrient ions until they are absorbed by the roots is just as important as the supply of those initial ions. Soil erosion is the most damaging force against top soil. Soil erosion happens anytime soil is bared and exposed to the elements. Wind and water have a dramatic effect on soil erosion because both events have a tendency to remove the humus particles and carry them away from the soil. The removal can be a slow and gradual process when soil is gradually

How has erosion effect beaches in recent times? In recent decades erosion has become a major issue to beaches around Australia‚ since beaches are temporary features. There is always sand being removed and sand being added to them‚ often‚ they change drastically during the year‚ depending upon the frequency of storms. Eventually‚ a beach erodes because the supply of sand to the beach cannot keep up with the loss of sand to the sea. The Sand dunes and vegetation help to hold the sand in place when

Landforms by Erosion (erosion is the main process) * High-energy waves * Rocks that are easily eroded 1) Cliff and shore platforms Point : A cliff is a high‚ steep rock face along the coast. Explanation: A cliff is formed when waves repeatedly pound against a rocky coast Elaboration: This weakens the rock‚ causing the lines of weakness to form in the rock face * Over time‚ the waves erode the coast to cut a notch along the lines of weakness. * The notch may be further

Soil erosion is a major concern in the southeastern region of Nigeria due to high population densities and farming techniques‚ which has resulted in the presence of numerous gullies. While gullies are found all around the world‚ the existence of gullies in Nigeria is regarded as one of the worst environment disasters‚ having negative implications on the environment and the quality of life for humans and other species (Adetona & Ezezika‚ 2011; Ajaegwu & al‚ 2010). Large quantities of soil in Nigeria

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. (iii) Nature of crop grown In India‚ as it has been noticed the dry crop producing regions (such as millet‚ maize‚ potato‚ tobacco‚ cotton and even wheat growing region)

The debate on the value of higher education for police officers continues to be one of the most persistent and pervasive issues in policing. Although there are several different interpretations of what constitutes a professional police officer there appears to be a consensus about the need for professionalism in policing. Researchers have attempted to measure performance through such variables as officer attitude‚ discretion‚ ethics‚ cynicism‚ decision-making‚ and use of deadly force. Despite the
