Mod F, Lesson 1.1 Weathering, Erosion, and Deposition Review

Weathering, Erosion & Deposition

Review

Weathering

-Breaks rocks apart

-Usually happens very slowly

-Agents of weathering include wind, water, ice, plant roots, gravity

-Creates sediment

Erosion

-Moves sediment

-Can happen quickly or slowly

-Agents of erosion include wind, water, ice (glaciers), gravity

Deposition

• Drops eroded sediment off in a different place
• Occurs when water slows down
• Results in the formation of a delta at the mouth of a river

Multiple Select

Check all of the agents of weathering.

• wind

• water

• gravity

• ice

Multiple Choice

_____________ is the dropping off/ depositing of rocks.

• Metamorphosis

• Deposition

• Weathering

• Erosion

Multiple Choice

What is the difference between weathering and erosion?

• Erosion breaks down the rocks, and weathering carries the broken pieces away.

• Erosion carries broken pieces away, and weathering builds the pieces back up into another land mass.

• Weathering carries broken pieces away, and erosion builds the pieces back up into another land mass.

• Weathering breaks down rocks, and erosion carries the broken pieces away.

Multiple Choice
