• Erosion

• Weathering

• Deposition

• Sediment

A type of weathering caused by repeated freezing and thawing of rock.

• Frost Wedging

• Tree Root Wedging

• Abrasion

• Erosion

A type of weathering caused by the scraping of rock such as in a river or glacier

• Frost Wedging

• Abrasion

A type of weathering caused by growing roots which can break rock.

• Deposition

• Frost Wedging

• Abrasion

• Tree Root Wedging

A slow moving river of ice

• Glacier

• Ice

• Deposition

• Erosion

The process where weathered rock sediment is deposited (dropped) in another location such as the mouth of a river, eventually creating a new landform.

• Weathering

• Deposition

• Erosion

• Abrasion

When water and wind move the weathered rock sediment towards the ocean.

• Glacier

• Weathering

• Deposition

• Erosion

A method of controlling erosion where trees are planted between a farmer's fields to break up the wind.

• Wind Break

• Fallow Field

• Weathering

• Erosion

A farmer's field where no crops are planted. This causes erosion because wind and water can take soil away.

• Wind Break

• Glacier

• Fallow Field

• Erosion

Natural land formations on the Earth's surface.
