Abrasion is the process of rocks and sediment wearing away by the actions of water, wind, or ice carrying and rubbing particles against the surface. Ice wedging occurs when water seeps into cracks in rocks, freezes, expands, and causes the rock to break apart over time as the ice expands.
Some forms of mechanical weathering include frost wedging (freeze-thaw cycle), root wedging (roots growing into cracks), abrasion (rock being worn down by friction), and exfoliation (layers of rock peeling off due to pressure release).
The four types of mechanical weathering are frost wedging (freeze-thaw cycles causing cracks in rocks to expand), exfoliation (peeling away of outer layers due to pressure release), thermal expansion (rocks expanding and contracting due to temperature changes), and root wedging (roots growing in cracks and breaking apart rocks).
