Glacier
a large mass of moving ice
What is a Glacier
glaciers that form in valleys in high, mountainous areas
What is Valley Glacier
when wind keeps material suspended in the air
what is suspension
pile of windblown sand
what is a dune
slow downslope movement of particles that occurs on every slope covered with loose, weathered material.
what is creep
where valley glaciers scoop out deep, bowl shaped depressions
What is a cirque
glaciers that cover broad, continent-sized areas
What is Continental Glaciers
the movement of hard particles such as sand over an uneven surface in a turbulent flow of air or water.
what is saltation
The dune that forms crescent shapes and forms from a small amount of sand
What is Barchan Dune
A fluid or hardened stream of mud
What is mudflow
the process of a glacier breaking off pieces of rock
What is Plucking
area where more snow falls then melts
What is a snowfield
erosion by wind of loose material from flat areas of dry, uncemented sediments
what is deflation
Dune that forms a series of ridge shapes and formed from a large amount of sand
What is tranverse dune
when dirt, rock or other pieces of earth begin to slide down a mountain or slope
what is landslide
unsorted ridges of till
What is a moraine
the largest glacier on the planet
What is Antarctica
the mechanical scraping of a rock surface by friction between rocks and moving particles during their transport
what is abrasion
The dune that forms U-shapes and forms from a large amount of sand
What is Parabolic Dune
a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or rock layers moves a short distance down a slope
what is slumps
The area at the leading edge of the glacier where the meltwater flows and deposits outwash
What is outwash plain
area where snow accumulates at
What is Zone of Accumulation
