Weathering is the process that changes solid rock into sediments With weathering rock is disintegrated into smaller pieces Once these sediments are separated from the rocks erosion is the process that moves the sediments away from it s original position The four forces of erosion are water wind glaciers and gravity

Chemical weathering is the breaking down of rocks using the atmospheric chemicals to do so This process can become intense where the climate is hot and wet All rocks on this Earth s surface go through a cycle known as The Rock Cycle where there is a group of changes that the rocks are forced to go through in a sequenced event

Physical weathering also called mechanical weathering is a process that causes the disintegration of rocks mineral and soils without chemical change The primary process in physical weathering is abrasion the process by which clasts and other particles are reduced in size Physical weathering can occur due to temperature pressure frost

Explanation Mechanical weathering or physical weathering is done by water or thermally When water gets in between rocks and crevices in the mountains and it freezes rocks will expand since frozen water expands causing a physical expansion of rock Also being exposed to sunlight and thermal heat rock on the mountain will also expand and
