Document Summary
Third quiz: processes producing sediment deposits, weathering. Weathering the sum total of the processes which break rock down into loose pieces (called sediment) and material dissolved in water. Mechanical weathering breaks rock bodies down into smaller pieces without any change in composition: mechanisms of mechanical weathering. Temperature extremes experienced at the earth"s surface. Chemical weathering rocks react chemically with other materials at the earth"s surface (primarily water and the atmosphere) to form new solid materials and/or ions in solution: mechanisms of chemical weathering. Weathering produces loose rock material called sediment. Sediment that can support the growth of rooted plants is called soil: mass wasting. Mass wasting the downslope movement of sediment due to the pull of gravity. Mass wasting can occur suddenly, for example in landslides, or very slowly, in which case it is called soil creep: erosion. Erosion the transport of loose rock material by mobile agents such as wind, water, or the moving ice of glaciers.
