Weathering, Erosion, Deposition

Front

What is chemical weathering?

Back

The breakdown of rocks due to chemical reactions and processes.

Front

What is deposition?

Back

The process in which sediment settles out (drops to the bottom) of the water or wind that is carrying it.

Front

What is erosion?

Back

The process in which wind, water, ice, or gravity move rock fragments from one location to another.

Front

How do physical and chemical weathering differ?

Back

Only chemical weathering produces new materials.

Front

What is an example of erosion?

Back

Wind blowing sand from one location to another.

Front

What is physical weathering?

Back

The breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What role does water play in weathering?

Back

Water can cause both physical and chemical weathering by freezing and thawing or by dissolving minerals.

Front

What is sedimentation?

Back

The process of settling or being deposited as sediment.

Front

What is the main cause of erosion?

Back

Natural forces such as wind, water, ice, and gravity.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken pieces.
