Mass Movement
This is where all mass movments occur.
These landforms are usually formed near Earth's poles and in mountainous areas at high elevation.
What are glaciers?
Wind erosion can cause:
a. mudflows
b. deflation
c. slump
d. none of the above
B
This acts as a lubricant between grains of soils and sediment. ____
water
When two cirques on opposite sides of a valley meet, they form a(n) ____.
arete
A telephone pole shifting on a hill is an example of this type of mass movement.
Creep
The two types of glaciers are : ____.
What are valley glaciers and continental glaciers?
This term refers to thick, windblown silt deposits.
What is loess?
False!
True or False: Only valley glaciers flow
False
Why is it a bad idea to build a house on landslide-prone land?
The house adds additional weight, which could make it more unstable/prone to landslides.
This happens when glaciers remove and scrape rocks with other rocks.
What is plucking?
large piles of sand created by erosion and deposition.
What are dunes?
Cirques, horns, and hanging valleys are all examples of ____.
Features created by glacial erosion
Do the effects of gravity increase on steeper slopes?
Yes
Building construction, roadways, and poor septic system maintenance are examples of _____ on mass movement.
What is human impact?
Glaciers cover this percentage of the land on Earth.
What is ten percent?
How does wind deposition occur?
When velocity decreases, the wind's velocity will slow down. The materials that cannot be carried will drop, forming a deposit on the ground.
The Great lakes and finger lakes of New York are examples of these.
Moraine-dammed lakes
Ridges made of sands and gravels, deposited by glacial meltwater flowing through tunnels within and underneath glaciers, or through meltwater channels on top of glaciers
Eskers
These are the 4 types of mass movement.
What are: creep, flows, slides, and rockfalls?
This landmass has the greatest number of glaciers.
What is Antarctica?
Where does wind erosion typically occur?
Areas with little vegetation cover (deserts, seashores, lakeshores, semi-arid areas)
water reduces the frictional contact between grains of soil and acts as a lubricant between surface materials and underlying layers. The weight of the additional water pulls material downhill.
