Health is wealthMechanical Weathering
Mechanical weathering is the physical breakdown of rocks by natural processes. Mechanical weather involves the breakdown of soil or rocks by direct contact with the environment. Mechanical weathering processes do not alter the chemical structure of the rock, but will break it down into smaller pieces. Examples of elements that cause mechanical weathering are heat (sun), cold (ice), pressure and water. Its primary method is the alteration in size that the particle would go through and it definitely grow small because of weathering. There are several forms, including ice wedging and abrasion. In ice wedging, water fills cracks in rocks, freezes, and expands which causes the crack to widen. Abrasion occurs when friction between the rock and surfaces such as water or riverbeds causes the rock to wear down.
