I will pay for the following article Soil Horizon. The work is to be 5 pages with three to five sources, with in-text citations and a reference page. Mechanical Weathering is the cutting or reshaping of the surface done by the Earth’s atmospheric elements (Monroe & Wicander, 2012, p.137). This breaking down process is caused by physical contact with the atmospheric elements which include heat, water and pressure. For example, rocks can be disintegrated by simply expansion and contraction by a change in atmospheric temperature. Similarly, the surface can be damaged by the change in pressure. On any surface, the layers below are under pressure by the weight of the surface above. In case of erosion when the higher surfaces change, the pressure is decreased and different surfaces tend to expand under the conditions of changed pressure. Therefore, expanding and exerting pressure on parallel surfaces under new pressure conditions.
Changes are done to the surface when atmospheric elements carrying chemical agents come in contact with the surface. Acid rain is one example of these elements and contains sulfuric acid. When it comes in contact with rocks the chemical reaction changes composition in some cases and causes weathering.
Spheroidal Weathering is a form of Chemical Weathering in which the larger rocks form a rounded shape. In simple the weathering, in this case, takes away the joints and edges of large blocks as they are more exposed to atmospheric elements. Water creeps into cracks and edges and they are taken off the surface gradually. A round surface is formed which presents an equal area exposed to atmospheric elements.
Leaching is the process in which minerals in the top layer of the soil are mixed with water and are carried to lower layers as the water seeps into the surface. Many valuable nutrients are absorbed by water and are deposited in lower layers, whereas, the non-soluble materials remain on the top surface.
Creep is the deformation or disintegration of materials after being exposed to external stresses for a long period of time. This effect increases with an increase in the magnitude of stresses. Heat and pressure are the main stresses and their magnitude is proportional to the effect.
