Weathering
What is weathering?
The process of breaking down matter into sediment.
What is erosion?
The movement of sediment caused by weathering.
What is deposition?
The settlement of weathered and eroded sediment.
What are the agents of weathering?
Water, wind, and ice.
What are the agents of erosion?
Water, wind, and ice are the main ones, while gravity plays a small role.
What are the agents of deposition?
Water, wind, and ice are the main ones, while gravity plays a small role.
What is physical weathering?
The process of breaking down matter into sediment without changing any of the chemical composition.
True or false: sand dunes are made because of erosion
False
True or false: deltas are made because of deposition
True
Name an example of physical weathering.
Abrasion, frost wedging, salt wedging, root penetration, exfoliation, etc.
Name an example of a landform created in part because of erosion.
Coastlines, rivers, mountains, glaciers, lakes, etc.
Name an example of a landform created by deposition that is NOT deltas
lakes, glaciers, coastlines, etc.
What is chemical weathering?
The process of breaking down matter into sediment while changing at least one part of the matter's chemical composition.
Water and wind.
What are the two elements that cause oxidation (chemical weathering)?
Oxygen and Hydrogen
