Landforms Review

Front

What are River Deltas?

Back

River Deltas are landforms created by the deposition of sediment at the mouth of a river, where it meets a body of water. They are formed through constructive processes.

What landform is formed by the accumulation of sediment in a river?

Back

River Delta.

What is a Sea Arch?

Back

A Sea Arch is a natural rock formation that is formed by the erosion of cliffs by wave action, creating an arch shape.

What is an Island?

Back

An Island is a piece of land that is surrounded by water on all sides, often formed by volcanic activity or the accumulation of sediment.

Front

What is Deposition?

Back

Deposition is the constructive process in which sediment is dropped in a new location, forming new landforms over time.

What is Erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by wind, water, or ice.

Front

What is Weathering?

Back

Weathering is the breaking down of rocks and minerals into smaller pieces by natural processes such as wind, water, and temperature changes.

Front

What are Constructive Processes?

Back

Constructive Processes are natural processes that create new landforms, such as deposition and volcanic activity.
