Weathering and Erosion

Which of these would be the BEST example of chemical weathering?

• Limestone rocks dissolving in water

• Plant roots growing through concrete and splitting it

• Waves carrying sand away from a beach

• A large rock splitting into pieces because of ice

Which is an example of CHEMICAL weathering?

• Frost wedging

• Animal activity

• Plant growth

• Acid rain

How do the processes of weathering and deposition differ?

• Weathering breaks down rocks and deposition leaves them in new places

• Weathering has to do with air and deposition has to do with plants

• Weathering occurs only in summer and deposition occurs year-round

• Weathering can be chemical or physical and deposition is only chemical

The process that changes solid rock into sediments.

• Fracture

• Dissolution

• Weathering

• Erosion

Factors that determine how much erosion runoff can cause include -

• whether the land is bare or covered with plants.

• how fast the water is moving.

• how much water is flowing.

• all of the above

The process that moves sediments

• Erosion

• Weathering

• Dissolution

• Fracture

Weathering can change roads, sidewalks, buildings and sculptures over time.

• True

• False
