100
the boundary between land and a body of water

100
wind deposits what type of particles first as it starts to slow down
What is heavier particles?
100
two main types of glaciers
What are continental and alpine glaciers?
100
the sudden movement of rock and soil down a slope
What is a landslide?
200
the rock material carried and deposited by glaciers
What is glacial drift?
200
water that moves in a zigzag pattern along the shore
What is a longshore current?
200
very fine sediments deposited by the wind
What is loess?
200
unsorted rock material that is deposited directly by a melting glacier
What is a till?
200
the slow downhill movement of weathered rock material
What is creep?
300
a group of loose rocks that fall down a steep slope
What is rock fall?
300
this is released when a wave breaks
What is energy?
300
removal of fine sediment by wind
What is deflation?
300
a broad area of sorted material deposited in front of a glacier
What is an outwash plain?
300
mudflows of volcanic origin that can travel at speeds greater than 80 km/h
What are lahars?
400
a glacial deposit that has been sorted and layered by the action of streams or meltwater
What is stratified drift?
400
this is a result of wave deposition
What is a sandbar or barrier spit?
400
skipping and bouncing movement of sand-sized particles in the direction the wind is blowing
What is saltation?
400
a depression formed when sediment builds up around a melting block of ice left behind by a glacier
What is a kettle?
400
the steepest angle (slope) at which loose material will not slide downslope
What is angle of repose?
500
the movement of any material, such as rock, soil, or snow, downslope
What is mass movement?
500
the size of a wave depends on these two things
What is how hard the wind is blowing and how long the wind is blowing?
500
mounds of wind-deposited sand
What are dunes?
500
till deposits produced when glaciers carry material to the front and sides of glacial ice
What are moraines?
500
four types of rapid mass movement
What are rock falls, landslides, mudflows, and lahars?
