In earth science, erosion is the action of surface processes (such as water flow or wind) that remove soil, rock, or dissolved material from one location on the Earth's crust, and then transport it to another location (not to be confused with weathering which involves no movement).
1 Soil Erosion Causes and Effects: Introduction Soil erosion is one form of soil degradation along with soil compaction, low organic matter, loss
Soil health is defined by the ability to perform essential ecosystem functions such as: nutrient cycling, water filtration, and habitat provision for plants and animals.
19 Agri-science Resources for High School Sciences Physics Soil Erosion Introduction Soil is the top layer of the earth's surface that is capable of sustaining life. Therefore, soil

Sediments in the aquatic ecosystem are analogous to soil in the terrestrial ecosystem as they are the source of substrate nutrients, and micro- and macroflora and -fauna that are the basis of support to living aquatic resources.

Sexual Reproduction Any process of reproduction that does involve the fusion of gametes. Shale Fine grained sedimentary rock composed of lithified clay particles.
Without plant cover, erosion can occur and sweep the land into rivers. The agricultural plants that often replace the trees cannot hold onto the soil and many of these plants, such as coffee, cotton, palm oil, soybean and wheat, can actually worsen soil erosion.
Soil is the material found on the surface of the earth that is composed of organic and inorganic material. Soil varies due to its structure and...
Learn about the processes of weathering and erosion and how it influences our planet.
Deforestation Effects, Causes, and Examples List - Over half of the world's forests have been destroyed in the last 10,000 or so years -- the majority of
Deforestation, the permanent destruction of forests in order to make the land available for other uses, is considered to be a contributing factor to global climate change.
Soil erosion is the displacement of the upper layer of soil, one form of soil degradation.This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, animals, and humans.
In this lesson, students explore and verify that soil erosion is affected by the makeup of the soil using plant roots, rocks, and the slope of the land as experimental factors.
Purpose. To demonstrate the devastating effects of soil erosion and its impact to the world's agriculture.

Soil: Soil, the biologically active, porous medium that has developed in the uppermost layer of Earth's crust. It is one of the principal substrata of life on Earth, serving as a reservoir of water and nutrients, as a medium for the filtration and breakdown of wastes, and as a participant in the cycling of elements.
After the Fire: Indirect Effects on the Forest Soil Fire's most significant indirect effects on soil are caused by the alteration of standing vegetation and the consumption of organic matter within and beneath the forest floor (DeBano et al. 1998, Neary et al. 1999).
Assessing the impacts of climatic and, in particular, land use changes on rates of soil erosion by water is the objective of many national and international research projects.
Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water () and wind or through forces associated with farming activities such as tillage.
