Weathering Erosion and Deposition (WED)

Weathering

weathering ndash the breaking down of rock into smaller pieces (sediment) usually by wind water or ice

Weathering is a destructive force

Weathering happens slowly

Agents of Weathering

bull Wind bull Water bull Ice (Glaciers) bull Biological (Plant RootsAnimal) bull Temperature Change bull Chemical (Acid)

Erosion

erosion ndash the movement of weathered rock (sediment) by wind water ice or gravity

Erosion is a destructive force

(Weathering is also a destructive force)

Erosion can happen slowly or quickly

Agents of Erosion

bullWater

bull Ice (Glaciers)

bullWind

bullGravity

Fast Erosion Examples

Slow Erosion Examples

Deposition

deposition ndash the process by which weathered rock particles soil particles organic particles or dissolved mineral particles are dropped or deposited from erosion in a new location

Deposition is a constructive force

Deposition can happen slowly or quickly

Agents of Deposition

bullGravity

bullWhen Erosion Stops

Fast Deposition

bull Landslides

bull Mudslides

bull Floods

bull Monsoons

bull Volcanoes

Slow Deposition

bull Deltas

bull Meandering rivers
