Weathering and Erosion

Weathering is the member whereby rocks exposed to the atmosphere atomic number 18 broken drop into soil. Erosion is the process by which the come to is sculpted or worn out-of-door by agents of eating away (wind, rivers etc) and material is transported and deposited away from its source. What is the difference between weathering and erosion? When a rock or tinge is loose it is weathering and once that particle starts moving from its sure place it is erosion. The main types of Weathering 1. mechanical / material weathering is the disintegration/ crack-up of rocks into smaller fragments. 2. Chemical weathering is the decomposition/ declination of minerals in rocks or organic materials. 3. Biological / Biotic weathering- is the crumbling of rocks through and through the work of plants and animals. windup(prenominal) / Physical Weathering Mechanical weathering break-dances up rocks and does not lurch its mineral composition. The rock particles be n ot softened, and do not change their colour. Rock particles created by visible weathering can be further altered and broken dispirited by chemic weathering. Physical weathering takes place mostly in regions where there is right smart daily range of temperature. close to rocks that are jointed break up into blocks and this is known as block disintegration.

Some rocks dismantle off into layers, like onions this process is called exfoliation. Abrasion -physical wearing down of rocks as they rub or bounce against each other--most greens in windy areas, infra glaciers, or in well out channels. Process of Mechanical weathering: Frost action - Weathering occurs in place! s with temperatures alter above and under 0ºC. During the day water from rain, dew or melting light speed seeps into cracks in rocks. At night the temperatures wane and the water in the rocks is turned into ice. When the ice freezes it expands creating pressure and the cracks are forced wider, ptyalise rocks apart. The rocks then form heaps of run off these are called screes.
