Front

What causes erosion?

Back

Water, ice, wind, or gravity can cause erosion by moving fragments of rock and soil.

Front

What is deposition?

Back

The process by which water, ice, wind or gravity deposit rock sediments and soil in a new place.

Front

How does wind contribute to erosion?

Back

Wind can blow sand from one location to another, moving soil and rock fragments.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion moves the broken pieces to new locations.

Front

Give an example of weathering.

Back

Wind blasting sand at rock and carving out caves.

Front

What role does gravity play in erosion?

Back

Gravity pulls rocks and soil down slopes, causing them to move.

Front

What is mechanical weathering?

Back

The physical breaking down of rocks into smaller pieces without changing their chemical composition.
