Weathering, Erosion & Deposition

Front

What is weathering?

Back

The process by which rocks are broken down into smaller pieces by natural forces such as wind, water, and temperature changes.

Front

What is erosion?

Back

The process by which soil and rock are removed from one location and transported to another by natural forces such as water, wind, or ice.

Front

What is deposition?

Back

The process by which sediments, soil, and rocks are added to a landform or land mass, often occurring after erosion.

Front

What causes the greatest amount of erosion on beaches?

Back

Waves.

Front

What is physical weathering?

Back

The breaking down of rocks into smaller pieces without changing their chemical composition, often caused by temperature changes, freezing, and thawing.

Front

What is chemical weathering?

Back

The process that breaks down rocks through chemical reactions, changing the minerals in the rocks.

Front

How do plants contribute to weathering?

Back

Plants weather rocks by growing roots into cracks, which expand and break the rocks apart.

Front

What is an example of physical weathering?

Back

Water getting into cracks, freezing, and breaking rocks apart.

Front

What is an example of chemical weathering?

Back

Acid rain reacting with limestone and dissolving it.

Front

What role does gravity play in erosion?

Back

Gravity pulls rocks and soil down slopes, contributing to erosion.
