Which term BEST describes the rate at which glacial erosion takes place?
Quick
Short
Slow
Sudden
How would a sandblasted rock differ from a rock that hasn't been sandblasted?
A sandblasted rock would be bigger
A sandblasted rock would be smoother in shape and less jagged
A sandblasted rock would be composed of volcanic material
A sandblasted rock would be covered by water
What do floodplains, sandbars, and river deltas have in common?
They've all been formed by water erosion
They've all been formed by glacial erosion
They've all been formed by wind erosion
They've all been formed by sandblasting
Why is it hard to see glacial erosion in action?
Because glaciers are so big
Because light from glaciers refracts too much
Because glaciers move very, very slowly
Because glacial erosion is usually very subtle
Based on the information presented in the video, what can you infer about the type of erosion that formed the Grand Canyon?
WInd erosion
Water erosion
Sandblasting
Glacial erosion

What is one mass movement that occurs quickly from weathering, erosion, and deposition?
landslides or mudslide
mountain building
creeps
formation of caves
What is the main agent that causes landslides, mudflows, slumps, and creeps to occur?
water
gravity
ice
wind
When a glacier moves, it picks up and carries the rocks with it. These rocks are weathered by:
abrasion
exfoliation
thermal expansion
hydrolysis
What do we call the type of water erosion feature when it cuts off from the river ?
Meander
Oxbow lake
Waterfall
Valley
A loop like bend in the shape of the river as the river winds from side to side
Stream
Gully
Rills
Meander
An alluvial fan is
A wide sloping deposit of sediment from a plain
A wide sloping deposit of sediment from a narrow valley
A wide sloping deposit of sediment where a stream leaves a mountain
None of te above
The greatest stream velocities are found closest to points
A and B
B and C
C and D
D and A
The streambank on the outside of this meander is steeper than the streambank on the inside of this meander because the water on the outside of this meander is moving
faster, causing erosion
slower, causing erosion
faster, causing deposition
slower, causing deposition
At which point does the greatest stream erosion occur?
A
B
C
D
Which erodes/breaks down more rock:
A fast-moving stream
A slow-moving stream
