Best Answer

When rocks are broken down without any change to their chemical compositions it is mechanical weathering. Causes of mechanical weathering are Freezing and melting of water, Abrasion, when the rock is weather by an abrasive agent such as wind and sand, and exfoliation occurs when a rock is brought to the surface.

Rocks are mechanically weathered through physical processes such as frost wedging, where water freezes and expands in cracks, causing the rock to break apart. Other mechanical weathering processes include abrasion from wind, water, or ice, and root wedging as plant roots grow and exert pressure on the rock.

Mechanical weathering is simply the breakdown of rocks into smaller pieces by physical means. It does not affect a rock's chemistry and mineralogy.
