Weathering
Erosion and Deposition
Water Erosion
Wind and Ice Erosion
Miscellaneous
100
The process that breaks down rock and other substances over time
What is weathering?
100
The movement of weathered material or sediment from one location to another
What is erosion?
100
Water that moves over the surface when it rains
What is runoff?
100
The weakest form of erosion
What is wind?
100
This feature is formed when a meander is cut off from a river.
What is an oxbow lake?
200
The two types of weathering
What is Mechanical and Chemical Weathering?
200
Material moved by erosion
What is sediment?
200
When sediment is deposited where a river flows into an ocean or lake, this is formed.
What is a delta?
200
A large mass of ice that forms on land and moves slowly across Earth's surface
What is a glacier?
200
Fine, wind-deposited silt and clay
What is loess?
300
The grinding away of rock by rock particles carried by water, ice, wind, or gravity
What is abrasion?
300
One of the forces that cause erosion
What are gravity, running water, glaciers, waves, and wind?
300
A wide, sloping, fan-shaped deposit of sediment where a stream leaves a mountain range
What is an alluvial fan?
300
Deposits of wind blown sand
What are sand dunes?
300
These features are formed by rivers as they erode the sides of a mountain
What are valleys?
400
One of the agents of chemical weathering
What are Water, oxygen, carbon dioxide, living organisms, and acid rain?
400
The laying down or settling of eroded material.
What is deposition?
400
One of the factors that affect surface runoff
What are amount of rain, vegetation, type of soil, shape of the land, and how people use the land.
400
The process when a glacier picks up rocks as it moves over the land
What is plucking?
400
Features that are formed as weathered sediment carried by wind cuts and polishes exposed rock. McDonalds has two of them.
What are arches?
500
One of the forces of mechanical weathering
What are Freezing and Thawing, Release of Pressure, Growth of Plants, Actions of Animals, and Abrasion
500
Processes such as landslides, mudflows, slump, and creep that are caused by gravity and move sediment downhill.
What is mass movement?
500
These are the two factors that affect erosion by a river
What are the slope of land and flow rate of water?
500
Rocks that form when windblown sand, silt, or ice bombard them
What is scoured or sandblasted rock?
500
One of the features that are formed by glaciers, after they have carved the land through abrasion
What are valleys or lakebeds?
