Weathering and Erosion

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through physical, chemical, or biological means.

Front

What is erosion?

Back

Erosion is the movement of sediment or soil from one location to another, often caused by wind, water, or ice.

Front

How does freezing water cause weathering of rocks?

Back

Freezing water expands cracks in rocks, which can lead to breaking them apart.

Front

What is deposition?

Back

Deposition is the process where sediment is laid down in new locations after being transported by erosion.

Front

What role does water play in weathering?

Back

Water can cause both physical and chemical weathering, breaking down rocks and minerals.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion moves the broken pieces away.

Front

What is an example of physical weathering?

Back

An example of physical weathering is the cracking of rocks due to freeze-thaw cycles.

Front

What is an example of chemical weathering?

Back

An example of chemical weathering is the rusting of iron in rocks when it reacts with oxygen and water.

Front

How do plants contribute to weathering?

Back

Plants can contribute to weathering through root growth, which can break apart rocks.

Front

What is soil formation?

Back

Soil formation is the process that occurs as weathering breaks down rocks into smaller particles that mix with organic material.
