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 and soil from one location to another, often caused by water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process where sediment is dropped or settled in a new location, often forming new landforms.

Front

How does ice contribute to weathering?

Back

Ice can freeze and expand in cracks of rocks, causing them to split apart.

Front

What role does water play in erosion?

Back

Water can carry away soil and sediment as it flows, leading to erosion of the land.

Front

What is an example of physical weathering?

Back

An example of physical weathering is when rocks are broken down by temperature changes, causing them to crack.

Front

What is an example of chemical weathering?

Back

An example of chemical weathering is when acid rain reacts with minerals in rocks, changing their composition.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion moves the broken pieces away from their original location.

Front

How do glaciers cause erosion?

Back

Glaciers can scrape and carry away large amounts of sediment as they move over land.

Front

What is the impact of wind on erosion?

Back

Wind can pick up and transport small particles of soil and rock, leading to erosion, especially in dry areas.
