What is the process when particles stop moving and settle where erosional agents have carried them?

• erosion
• deposition
• weathering
• abrasion

What is the scraping of smaller sediments against rocks called?

• erosion

• abrasion

What is the difference between mechanical and chemical weathering?

• Mechanical weathering breaks down rocks in a chemical process; chemical weathering breaks down rock in a physical process.
• Chemical weather breaks down rocks in a chemical process; mechanical weathering breaks down rock in a physical process.
• Mechanical weathering is only done by substances; chemical weathering is done by wind only.

What are the two main agents of mechanical weathering?

• chemicals and water
• water and solutions
• wind and water
• wind and solutions

Which of the following is an example of chemical weathering?

• A glacier scraping away rock as it moves.
• abrasion
• rust

How did the Grand Canyon form?

• The Colorado river flowed over flat land, the water carved away rock, and created the canyon.
• The wind wore away at the rock over millions of years and created the canyon.
• Glaciers scraped away the rock and created the canyon.
