A delta is a landform that forms at the mouth of a river, where it meets a body of water, and is created by the deposition of sediment carried by the river.

Front

What conditions are necessary for sand dunes to form?

Back

Sand dunes form when there is loose sand and strong winds to move the sand around.

Front

What is a U-Shaped Valley?

Back

A U-Shaped Valley is a valley formed by the erosion of a glacier, characterized by its U-shaped cross-section.

Front

What is weathering?

Back

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

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass, often occurring in areas where the wind or water slows down.

Front

How does water contribute to weathering?

Back

Water can enter cracks in rocks, freeze, and expand, causing the rocks to break apart, which is a form of physical weathering.

Front

What is coastal erosion?

Back

Coastal erosion is the process by which coastlines are eroded by the action of waves, currents, and tides.

Front

What are sand dunes?

Back

Sand dunes are hills of sand formed by the wind, typically found in deserts or near beaches.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken pieces from one place to another.
