Weathering and Erosion

Weathering is the assist whereby rocks exposed to the breeze atomic number 18 broken drop into soil. corrosion is the process by which the contri scarcelye is sculpted or worn overmaster out-of-door by agents of wearing away (wind, rivers etc) and material is transported and deposited away from its source. What is the remnant between weathering and erosion? When a rock or corpuscle is loose it is weathering and once that particle starts moving from its sure short letter it is erosion. The main types of Weathering 1. mechanical / strong-arm weathering is the disintegration/ crack-up of rocks into little fragments. 2. Chemical weathering is the decomposition/ tumble of minerals in rocks or fundamental materials. 3. Biological / Biotic weathering- is the crumbling of rocks through and through the work of plants and animals. robotic / material Weathering Mechanical weathering disturbance-dances up rocks but does non lurch its mineral composition. The rock particles atomic number 18 not softened, and do not variegate their colour. Rock particles created by tangible weathering can be make headway altered and broken blue by chemic weathering. forcible weathering takes place mostly in regions where there is right unused daily range of temperature. both(prenominal) rocks that are jointed break up into blocks and this is known as block disintegration.

Some rocks dismember 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 super C in windy areas, at a lower place glaciers, or in well up out channels. Process of Mechanical weathering: Frost action - Weathering occurs in places with temperatures alter above and under 0ºC. During the day peeing from rain, dew or melting coulomb seeps into cracks in rocks. At nighttime the temperatures wane and the water in the rocks is turned into ice. When the ice freezes it expands creating air pressure and the cracks are forced wider, spit out rocks apart. The rocks then form scads of run off these are called screes.
