Mass wasting - Correct Answer the downhill movement of a large mass of rocks or soil due to gravity
Landslide - Correct Answer a slide of a large mass of dirt and rock down a mountain or cliff
Sorting (sediment) - Correct Answer during deposition sediment gets sorted by size shape and density
Deflation - Correct Answer The action of wind over a large area to remove small clastic particles, leaving
behind cobbles and larger rocks that form desert pavement.
Abrasion - Correct Answer The grinding away of rock by other rock particles carried in water, ice, or
wind
Dune - Correct Answer A hill or ridge of sand piled up by the wind
Loess - Correct Answer A thick deposit of fine, windblown dust and silt that provides an excellent base
of rich soil.
Glacier - Correct Answer A large mass of dense, compacted snow and ice that flows downhill under the
influence gravity.
Glacial drift - Correct Answer Sediments deposited by a glacier
Till - Correct Answer The sediments deposited directly by a glacier
Moraine - Correct Answer A ridge formed by the till deposited at the edge of a glacier.
Creep - Correct Answer the slow downhill movement of weathered rock material
, Slump - Correct Answer A type of mass movement that occurs when a mass of material moves down a
curved slope
Avalanche - Correct Answer A great mass of ice, earth, or snow mixed with rocks sliding down a
mountain
Turbulence (steam) - Correct Answer Rough water that does the work of plucking up particles of rock
and soil and lifting them into the stream.
Suspended sediment - Correct Answer very fine soil particles that remain in suspension in water for a
considerable period of time without contact with the bottom.
Saltation - Correct Answer The movement of sand or other sediments by short jumps and bounces that
is caused by wind or water
Delta - Correct Answer A landform made of sediment that is deposited where a river flows into an
ocean or lake
Alluvial fan - Correct Answer A wide, sloping deposit of sediment formed where a stream leaves a
mountain range
Windbreak - Correct Answer Row of trees or hedges planted to partially block wind flow and reduce soil
erosion on cultivated land.
Glacial flour or Rock flour - Correct Answer Rock flour, or glacial flour, consists of fine-grained, silt-sized
particles of rock, generated by mechanical grinding of bedrock by glacial erosion or by artificial grinding
to a similar size. ... If the river flows into a glacial lake, the lake may appear turquoise in color as a result.
Valley/mountain/alpine glacier - Correct Answer a glacier that is confined by surrounding mountain
terrain; also called a mountain glacier. Muddy River Glacier carves its way through forested mountains
near Frederick Sound in southeast Alaska. Typical of mountain glaciers, it is constrained on all sides by
mountainous terrain.
