Ewing's Erosion Test Review

What is mass movement?

• is the movement of any material down a slope caused by erosion by gravity
• depositional landform rising from the floor of a limestone cave
• a deep valley carved by flowing water
• the process by which weathered rock, sediment, or soil is moved to a new location

Landslides can be caused by

• heavy rainfall
• earthquakes
• undercutting by a stream
• rainfall, earthquakes, and undercutting

Which sentence describes how landslides are formed?

• Earth's surface is continuously changing
• Chemical and physical weathering and erosion are all key contributors to surface changes
• Landforms can be formed as a product of the changes that take place
• Weathering loosens water, rocks, and soil on hills and gravity pulls the materials down the hillside.

What is the most important agent of erosion?

• Running water
• Wind
• Sand
• Chemicals

As water in a river slows down, its ability to carry sediment ________________ and larger pieces fall to the bottom.

• decreases
• increases

How does water get underground?

• gravity pulls rainwater down through the ground
• it all forms underground

What erosional features does the underground erosion form? (choose 2)

• sea stack
• cave
• sinkhole
• valley

What is the difference between a cave and a sinkhole?

• They are the same thing
• A cave is an underground chamber; a sinkhole is a hole resulting from the collapse of the roof of a cave
• A sinkhole is one of the first steps in cave formation
• None of the above are true

What are glaciers?

• lots of snow
• huge masses of ice

What are the two different types of glaciers and where are they found? (Choose two)

• alpine - massive ice fields that cover entire landmasses
• continential- found in mountain valleys
• alpine - found in mountain valleys
• continental - massive ice fields that cover entire landmasses
