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.
Biologically, Chemically and Mechanically.
Three processes that mechanically weather rocks are frost wedging (freeze-thaw cycles), exfoliation (physical weathering due to pressure release), and abrasion (erosion caused by frictional forces).
Water can breakdown rocks mechanically through a process called hydraulic action, where water enters cracks and crevices in rocks. When this water freezes and expands, it exerts pressure on the rock, causing it to crack. Additionally, water can carry sediment and debris that effectively wear down rock surfaces through abrasion.
The rate of chemical weathering increases when a rock becomes more mechanically weathered, also called abrasion.
Some examples of clastic sedimentary rocks include sandstone, conglomerate, shale, and breccia. These rocks are formed from the accumulation of fragments of pre-existing rocks and minerals, which are then compacted and cemented together over time.
