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

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

Soil Pollution The process of contamination of the land surface of the earth is referred to as land pollution. It results from human activities that cause imbalance in nature. Dumping human and industrial waste harmful agricultural practices and exposing the land to harmful chemicals leads to the pollution of land. We speak of water and air pollution and rarely even think of the adverse effects of land pollution. Let me share with you some of the important facts about land pollution. Land

When I was researching for this essay explaining what soil and water conservation means to me‚ I found two quotes that really stuck out to me. One written by Franklin D. Roosevelt stated‚ “A nation that destroys its soils destroys itself. Forests are the lungs of our land‚ purifying the air and giving fresh strength to our people.”‚ and another that was written by an unknown author read‚ “Water is life’s mater and matrix‚ mother and medium. There is no life without water.” I am not sure about you

Eco L: Soil Diversity Introduction Soil is an ecological system consisting of inorganic minerals (sand‚ silt‚ clay‚ and nutrients)‚ pore spaces‚ water‚ gases‚ organic matter‚ living organisms‚ and plants (Thien‚ 2002). The soil is said to be stable structurally and chemically thus is considered an outstanding medium for soil organisms such as bacteria‚ fungi‚ protozoa‚ nematodes‚ arthropods‚ and earthworms. The potential habitats of these soil invertebrates are the spaces within the surface

These soil forming factors continue to affect soils even on "stable" landscapes. Materials are deposited on their surface‚ and materials are blown or washed away from the surface. Additions‚ removals‚ and alterations are slow or rapid‚ depending on climate‚ landscape position‚ and biological activity. Parent material. Few soils weather directly from the underlying rock . These "residual" soils have the same general chemistry as the original rocks. More commonly‚ soils form in materials that have
