Weathering, Erosion, & Deposition

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 erosion?

Back

Erosion is the process by which water, ice, wind, or gravity moves pieces of rock and soil from one location to another.

Front

What is deposition?

Back

Deposition is the process where sediment is dropped or settled by wind, water, ice, or gravity after being transported.

Front

How does a fast-moving river contribute to erosion?

Back

A fast-moving river can carry rocks and soil downstream, removing them from their original location.

Front

What role does gravity play in erosion?

Back

Gravity pulls rocks and soil down slopes, contributing to erosion through processes like landslides and mudslides.

Front

What happens during a mudslide?

Back

A mudslide is a rapid flow of mud and debris down a slope, which is a form of erosion.

Front

Is erosion a natural process?

Back

TRUE - Erosion is a natural process that shapes landscapes over time.

Front

What is the relationship between weathering and erosion?

Back

Weathering breaks down rocks into smaller pieces, while erosion transports those pieces to new locations.

Front

How does freeze-thaw weathering occur?

Back

Freeze-thaw weathering occurs when water enters cracks in rocks, freezes, expands, and causes the rock to break apart.

Front

What is an example of deposition?

Back

An example of deposition is when a river slows down and drops sediment, forming a delta at its mouth.
