Rocks and Weathering

Weathering, Erosion, and Deposition review

​

Weathering

• The breaking down of Earth's surface-

  can be caused by different things:

• Ice

• root wedging

• flowing water

• abrasion- rocks bumping and hitting each other

• wind

• weather

Multiple Choice

What is physical weathering?

• The process by which earth’s surface is broken down into smaller pieces.

• After pieces of the Earth are carried by erosion they are deposited somewhere else. Deposition means to deposit things somewhere else.

• A five-thousand-foot-deep canyon located in Arizona. It was carved by the Colorado River over millions of years and is one of the best examples of weathering and erosion.

Multiple Choice

Which one of these is an example of physical weathering?

Erosion is:

After pieces of the Earth are broken down through weathering, those pieces are moved through erosion. It’s the process of moving things from one place to another.

Deposition

After pieces of the Earth are carried by erosion they are deposited somewhere else. Deposition means to deposit things somewhere else.

Multiple Choice

What is deposition?

• An extremely cold liquid made from nitrogen gas being squeezed (compressed) really hard. It is -321 degrees Celsius (-196 degrees Fahrenheit) and is used to freeze things very quickly.

• A five-thousand-foot-deep canyon located in Arizona. It was carved by the Colorado River over millions of years and is one of the best examples of weathering and erosion.

• After pieces of the Earth are carried by erosion they are deposited somewhere else. Deposition means to deposit things somewhere else.
