Changes to the Earth's Surface

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

What is deposition?

Back

Deposition is the process where materials are added to a landform or land mass, often occurring when wind or water slows down and drops the sediment it carries.

Front

What are constructive forces?

Back

Constructive forces are natural processes that build up the Earth's surface, such as volcanic eruptions and sediment deposition.

Front

What are destructive forces?

Back

Destructive forces are natural processes that break down or wear away the Earth's surface, such as erosion and weathering.

Front

How do sand dunes form?

Back

Sand dunes form through the process of wind erosion and deposition, where wind moves sand and deposits it in mounds.

Front

What is a river delta?

Back

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

Front

What is the role of wind in shaping the Earth's surface?

Back

Wind can erode surfaces by carrying away sand and soil, and it can also deposit materials to form features like sand dunes.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces through physical, chemical, or biological means.

Front

What is a sea arch?

Back

A sea arch is a natural rock formation that is formed by the erosion of cliffs by waves, creating an arch shape.

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 materials from one place to another.
