Abrasion
The grinding and wearing down of rock surfaces by other rock or by sand particles
Deflation
The removal of fine sediment by wind
Dunes
Mounds of wind-deposited sand
Loess
Thick deposits of this windblown, fine-grained sediment
Glacier
A large mass of moving ice that forms by the compacting of snow by natural forces
Glacial Drift
All the materials carried and deposited by the glacier
Alpine Glacier
Glacier that forms in a mountainous area
Cirques
Bowl-shaped depressions
Aretes
A sharp ridge that formed between two cirques that are next to each other
Horn
When three or more aretes join together they form a shark peak
Continental Glaciers
Thick sheets of ice that may spread over large areas, including across entire continents
Creep
The extremely slow movement of material downslope
Rockfall
When loose rocks fall down a steep slope
Landslide
The sudden and rapid movement of a large amount of material downslope
Mudflow
A rapid movement of a large mass of mud
What can erode and move rock, sand, and soil particles
Wind
Sandblasting Effect
Blows millions grains of sand slowly eroding the rock by wearing away its surface
What happens after a deflation in the dessert
A desert pavement
What are the two glaciers
Alpine Glacier and Continental Glacier
What causes glaciers to move
Gravity
U-shaped Valley
Forms from a v-shape to a u after the glacier erodes a river valley
Hanging Valleys
Small glacial valleys that join the deeper, main valley. Hanging Valleys commonly form waterfalls after the ice is gone
What’s the difference between Continental Glaciers and alpine glaciers
Alpine glaciers form sharp and rugged features on landforms while Continental glaciers flatten and smooth the landscape
What factors contribute to a creep?
Water, plant roots, and burrowing animals
