May 21st - Weathering, Erosion, and Deposition Quiz

What is the process called when rocks are broken down into smaller pieces by water, wind, ice, or plant roots?

• Weathering

• Erosion

• Deposition

• Melting

Which of the following best describes erosion?

• The process of rocks being broken down into small pieces

• The process of moving pieces of rock and soil by water, wind, or gravity

• The process of dropping sediment in a new place

• The process of plants growing in rocks

What happens during deposition?

• Rocks are broken down into smaller pieces

• Sediment is moved by water, wind, or gravity

• Sediment is dropped in a new location

• Water freezes and expands in cracks

Why is the Grand Canyon a good example of erosion?

• It was formed by plants growing in rocks

• It was created by the dropping of sediment

• It is a large hole made by the constant removal of rocks by a river over millions of years

• It was formed by freezing and thawing of water in cracks

Imagine a beach where waves keep bringing in sand and building up sand dunes. Which process is mainly responsible for the creation of these sand dunes?

• Weathering

• Erosion

• Deposition

• Melting

Which of the following is an example of physical weathering?

• Physical weathering in Iceland

• Sand dunes in Death Valley

• Loess in Mississippi

• Natural arch in Jordan

What process created the natural arch in Jordan shown in the image?

• Water erosion

• Wind erosion

• Glacial movement

• Volcanic activity

Which landform is created by the deposition of wind-blown sand?

• Sand dunes in Death Valley

• Limestone shoreline in Guam

• Cracked rock in Iceland

• Rock formation in Bolivia

How does wind contribute to the formation of Loess in Mississippi, US?

• By breaking rocks into smaller pieces

• By depositing sediment to form a yellowish wall-like structure

• By melting ice to create rivers

• By causing earthquakes

Compare the effects of wind erosion and wind deposition as shown in the images. How are the landforms created by these processes different?

• Wind erosion creates new land, while wind deposition destroys land.

• Wind erosion shapes and removes rock, while wind deposition builds up new landforms with sediment.

• Wind erosion and wind deposition both only break rocks into smaller pieces.

• Wind erosion and wind deposition both only create sand dunes.
