Physical Weathering: A form of weathering characterized by the
mechanical disintegration of rock into smaller fragments but not
involving chemical change.
Frost Wedging: A form of physical weathering caused by cycles of
freezing and thawing of water in pores or cracks of rocks.
Chemical Weathering: A from of weathering involving chemical changes
