What is the process called when sediment is deposited in a new location by water, wind, or ice?

Back

Deposition

Front

What natural feature is built to protect coastal areas from flooding?

Back

Seawall

Front

What is a levee and what purpose does it serve?

Back

A levee is a human-made structure designed to prevent flooding by controlling the flow of water.

Front

What natural process forms sand dunes?

Back

Back

Because the moving water is what wears away the cliff.

Front

What is the term for the movement of sediment from one place to another by wind, water, or ice?

Back

Erosion

Front

What is the difference between erosion and deposition?

Back

Erosion is the process of moving sediment, while deposition is the process of laying down sediment in a new location.

Front

What are some common causes of coastal erosion?

Back

Waves, currents, storms, and human activities.

Front

How do human activities impact natural processes like erosion and deposition?

Back

Human activities can accelerate erosion and alter deposition patterns through construction, deforestation, and land use changes.

Front

What role do plants play in preventing erosion?

Back

Plants help stabilize soil and sediment with their roots, reducing the impact of wind and water.
