Weathering and Erosion: Key Concepts and Processes

Weathering

Process of breaking down rocks into smaller pieces.

Erosion

Movement of weathered materials by wind or water.

Mechanical Weathering

Physical breakdown of rocks without chemical change.

Chemical Weathering

Decomposition of rocks through chemical reactions.

Ice Wedging

Freeze-thaw cycles causing rock fractures.

Exfoliation

Layer peeling of rocks due to temperature changes.

Carbonic Acid

Weak acid formed from carbon dioxide in water.

Oxidation

Chemical reaction involving oxygen, altering minerals.

Granite Weathering Products

Granite typically weathers into clay minerals.

Spheroidal Weathering

Rounded rock formation due to weathering processes.

Differential Weathering

Uneven weathering leading to varied topography.
