Erosion & Deposition

Multiple Choice

Erosion is a process that breaks apart rock into smaller fragments.

• True

• False

Multiple Choice

ALL mass movements happen slowly over time.

• True

• False

Multiple Choice

Slumps are created when a mass of materials falls down a curved surface.

• True

• False

Multiple Choice

Leaning tree trunks or posts are an example of creep.

• True

• False

Multiple Choice

Rockfalls, rock slides, mudflows, & avalanches happen on flat surfaces.

• True

• False

Multiple Choice

Which of the following is not a type of erosion caused by gravity?

• Mass Movements

• Creeps

• Wind

• Slumps

Multiple Choice

Glaciers quickly move & tear up rock in the process.

• True

• False

Multiple Choice

As glaciers move they can perform a process called what?

• Creep

• Plucking

• Slump

• Mass Movement

Multiple Choice

Plucked sediments & rock fragments scour the ground below a glacier.

• True

• False

Multiple Choice

Wind can pick up any type of sediment no matter the size.

• True

• False

Multiple Choice

Deflation is when heavy materials are transported to new locations.

• True

• False

Multiple Choice

Abrasion is when sediments strike rock & the rock is slowly worn away.

• True

• False

Multiple Choice

Rill erosion can become gully erosion if it continue to erode the ground.

• True

• False

Multiple Choice

All water soaks into Earth's surface as soon as it hits the ground.

• True

• False

Multiple Choice

During stream erosion, if the flow continues to move alone it can pick up a 'load'.

• True

• False

Multiple Choice

Sheet erosion is when water is absorbed in the ground quickly.

• True

• False

Multiple Choice

If water continues to flow along the same path, it will create a channel.

• True

• False

Multiple Choice

When waves constantly pound against shore, they do not affect landscape.

• True

• False

Multiple Choice

During shore erosion, metric tons of sediment is moved along our shorelines.

• True

• False

Multiple Choice

Soil erosion is harmful to the environment because it removes topsoil.

• True

• False

Multiple Choice

Soil erosion is affected by waves crashing over a landscape.

• True

• False

Multiple Choice

Glaciers can melt & cause water to flow into cracks of rocks. Later when the water refreezes, the rocks are still whole & the glaciers pass over them.

• True

• False

Multiple Choice

Which type of erosion occurs when materials & sediment is pulled downhill?

• Wind

• Gravity

• Water

• Glaciers

Multiple Choice

Wind erosion transports by deflation & plucking.

• True

• False

Multiple Choice

Shoreline erosion happens as rivers hit the shoreline.

• True

• False

Multiple Choice

Water erosion can cause abrasion.

• True

• False

Multiple Choice

Soil erosion prevents plants from growing.

• True

• False

Multiple Choice

Deposition drops sediments at ALL times in any location.

• True

• False

Multiple Choice

When sediments are eroded they are not destroyed.

• True

• False

Multiple Choice

Deposition is caused by surface water, sand, wind, & glaciers.

• True

• False

Multiple Choice

Loess is caused by glaciers melting.

• True

• False

Poll

I can differentiate between weathering, erosion, & deposition.

• Yes, Extremely confident I can

• Maybe, I'm still struggling a little bit with differentiation

• No, I am still having trouble telling them apart
