five example mechanical physical weathering
Answer (1)
Answer:1. Frost Wedging: Water enters cracks in rocks, freezes and expands, exerting pressure that splits the rock apart over time.2. Abrasion: Rocks are worn down as they collide with other rocks or particles due to wind, water, or ice movement (e.g., in rivers or by wind-blown sand).3. Thermal Expansion and Contraction: Rocks expand when heated by the sun during the day and contract when cooled at night, which eventually weakens and fractures them.4. Exfoliation: Layers of rock peel away from the surface due to the release of pressure as overlying materials are eroded or removed.5. Root Wedging: Plant roots grow into cracks in rocks, expanding as they grow and forcing the rocks to break apart.
