Front

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 deposition?

Back

Deposition is the process by which sediments are laid down or deposited in a new location, often forming landforms like deltas and sand dunes.

Front

How do canyons form?

Back

Canyons form through the erosion of rock by flowing water, usually from a river, over thousands or millions of years.

Front

What is the role of rivers in forming deltas?

Back

Rivers carry sediments and when they slow down at the mouth, they deposit these sediments, forming a delta.

Front

What is the difference between erosion and weathering?

Back

Erosion involves the movement of sediments, while weathering is the breaking down of rocks without movement.

Front

What landforms are created by wind?

Back

Sand dunes and loess are landforms created by the action of wind.

Front

What is a U-shaped valley?

Back

A U-shaped valley is a valley formed by glacial activity, characterized by its steep sides and flat bottom.
