No, frost wedging is a physical weathering process caused by the expansion of freezing water in cracks and crevices of rocks. Chemical weathering involves the breakdown of rocks through chemical reactions rather than physical forces like frost.

Frost wedging is a form of mechanical weathering caused by the repeated freezing and thawing of water in cracks in rocks.
No, frost wedging is a physical weathering process, not a chemical one. It occurs when water seeps into rocks, freezes, and expands, leading to cracks and fractures in the rock. This repeated freeze-thaw cycle causes the rock to break apart over time.
Physical weathering, such as frost wedging or root wedging, does not alter the mineral composition of a rock. These processes break down rocks into smaller pieces without changing their chemical makeup.
Mechanical weathering. It refers to the breakdown of rocks into smaller pieces without altering their chemical composition. This can occur through processes such as frost wedging, abrasion, and root wedging.
Frost wedging
Mechanical weathering occurs when rocks are broken apart by physical processes such as frost wedging, root wedging, or abrasion. These processes break down rocks into smaller fragments without altering their chemical composition.
Some types are thermal stress, frost wedging, abrasion, pressure fractures (pressure release), hydraulic action, and salt crystal expansion.
Chemical reactions breaking down minerals is not associated with mechanical weathering. Mechanical weathering involves physical processes such as frost wedging, abrasion, and root wedging that break down rocks into smaller pieces without altering their chemical composition.
