Flashcards
Chemical Weathering
Chemical Weathering
A type of weathering that transforms rock into different compounds through chemical reactions.
Frost Wedging
Frost Wedging
The process of rock disintegration caused by repeated freezing and thawing of water in cracks.
Physical Weathering (Cold & Humid Climates)
Physical Weathering (Cold & Humid Climates)
Weathering that dominates in areas with fluctuating temperatures and sufficient water for freezing/thawing, leading to rock breakdown.
