100
This term means "to break apart rocks by physical processes" (Hints: Two words!)
What is mechanical weathering?
100
An area of land where all runoff drains into the same river system.
What is "watershed"?
100
Earth's movement that is responsible for a planetary year.
What is "revolution"?
100
Rocks that are shaped by windblown sediments.
What is "ventifacts"?
100
The comparison between the amount of water vapor that is actually in the air versus the amount of water vapor that the air could hold.
What is "relative humidity"?
200
This type of climate is where chemical weathering most readily occurs. (Hint: Two words!)
What is "warm and humid"?
200
The difference in elevation of a stream per mile.
What is "gradient"?
200
This causes the Earth to have seasons.
What is "the tilt of Earth's axis"?
200
The type of dune that forms when wind blows in all directions.
What is "star dune"?
200
The term used to describe all water that falls from the sky (whether frozen or liquid).
What is "precipitation"?
300
The process by which wind and ice erode rock by scraping against it.
What is abrasion?
300
The age of stream that flows swiftly through a steep valley and has steep sides.

300
This occurs when the Sun is directly above Earth's equator. (Hint: twice a year!)
What is "equinox"?
300
The lowering of the land surface caused from the wind's removal of surface particles.
What is "deflation"?
300
The layer of the atmosphere that is closest to Earth and also where weather is located.
What is "troposphere"?
400
The type of mass movement that occurs and causes straight fenceposts to become slightly tilted.
What is "creep"?
400
The boundary line between the zone of ablation and the zone of accumulation in a glacier.

400
The direction that wind blows. (Hint: From what area to what area?)
What is "from high to low pressure"?
400
The most common gas found in our atmosphere.
What is "nitrogen"?
500

What is "ice wedging"?
500
A bowl-shaped basin left in the mountains by glacial action.
