Deposition
100
Area in a glacier where more snow melts that it accumulates
What is the ablation zone
100
When wind bounces sediment along the ground
What is saltation
100
The slowest type of mass movement
What is creep
100
A high mountain amphitheare

100
Glacial landform that looks like a tear drop
What is a drumlin
200
The Matterhorn is an example of one of these
What is a horn
200
Main way that wind erodes existing rocks
What is abrasion
200
The type of mass movement that moves as a consolidated mass.
What is a slide
200
Landform created when plucking occurs on two sides of a ridge.
What is an arete.
200
Type of deposits left by wind.
What is sorted
300
Type of glacier that moves faster and has a thinner layer of ice
What is a valley glacier
300
The transport of small particles through the air by wind
What is suspension
300
The driving force behind mass movements
What is gravity
300
2 ways that humans increase chances of mass movements
What is building on steep slopes, forestry, high mountain roads.
300
Landform created by wind that can migrate due to saltation
What is a dune
400
Reason why glaciers move at different rates - faster in the middle and on top and slower on the sides and the bottom.
What is friction
400
Similarity between dunes and moraine
What is both are created by deposition
400
Two factors that define the extent to which mass movement will occur.

400
Structures that are shaped by wind blown sediments
What are ventifacts
400
Only glacial landform to have sorted deposits

What are factors that influence the occurrence of mass movement.
500
factor that increase chances of wind erosion.
