Mechanical weathering definition biology

WebMechanical weathering is the application of force to physically fragment rock into smaller pieces called clasts. It breaks down rocks by the exertion of a physical force, and does not involve any chemical change. Some examples of it are: Freeze-thaw weathering Water seeps into cracks in rocks WebThe transfer of rock and soil downslope under the influence of gravity. Erosion The physical removal of material by mobile agents such as water, wind, ice, or gravity. Mechanical weathering Physical forces break rocks into smaller pieces without altering rock's mineral composition (DISINTEGRATION) Frost wedging (mechanical)
