Where is erosion due to wind the most common?
Desert
100
These are mounds of sand that are deposited due to wind.
Dunes
100
How does a glacier deposit or drop of materials?
Melting
100
When severe rainfall occurs and large masses of mud move from one area to another.
Mudflow
100
The part of Earth made up primarily of gases.
Atmosphere
200
What causes creep to occur?
Gravity
200
When rocks and sediment collide with other rocks/sediment.
Abrasion
200
What are the two types of glaciers?
Alpine and Continental
200
The slow process of rock and materials eroding from one area to another due to gravity.
Creep
200
This is the breakdown of rock.
Weathering
300
What is the difference between creep and a landslide?
Creep is very slow while a landslide is very fast.
300
This is the process of smaller sediment being moved while heavier sediment is left behind.
Deflation
300
Where are Alpine glaciers found?
Mountainous areas
300
When pieces of rock fall down to a lower area.
Rockfall
300
Water found under Earth's surface.
Groundwater
400
The materials carried and deposited by glaciers.
Glacial Drift
400
This is very small sediment that can travel great distances.
Loess
400
Where are continental glaciers found?
Flatter areas
400
The rapid movement of materials down a slope from one area to another.
Landslide
400
What process occur when water gets trapped inside cracks in a rock, freezes, expands, and breaks the rock apart?
Ice Wedging
500
Why would MORE erosion happen in a desert as opposed to a farm?
The sediment is smaller. Also, plant roots hold the soil in place.
500
How is loess different than other sediment?
Rich in nutrients.
500
What conditions must be necessary for glaciers to form?
Cold temperatures and snowfall
500
How is a landslide different from creep?
Speed
500
What two factors determine how much a coastline erodes?
Energy of waves and hardness of rock on the coast
600
A mudslide is a type of mass movement caused by _________.
Gravity
600
What characteristic of loess makes it a very valuable resource?
Loess is rich in minerals.
600
When glaciers retreat, they leave behind huge blocks of ice. When these ice blocks melt, they can form kettle lakes. Why is it important for sediment to build up around the ice blocks for kettle lakes to form?
Without the sediment, the water would not stay contained.
600
What conditions must exist for a glacier to form?
It must be cold, and more snow must fall than melts
600
What agent is most likely responsible for the formation of the sand dunes?
Wind
