chapter 27.1 and 27.2 Flashcards
what are the two types of glaciers
valley glaciers
continental glaciers
where do valley glaciers form
high, mountainous regions
where do continental glaciers form
large land areas in colder climates
where are the two continental glaciers located
Greenland
Antarctica
what are cirque
bowl shaped basin
how do aretes form
form where 2 adjacent valley glaciers meet and erode a long, sharp ridge line
what is a horn in a mountainous region
sharpened peaks
what shape of valleys do valley glaciers make
U-shaped valleys
what is a tributary glacier
small glaciers that feed into larger glaciers
what types of valleys do tributary glaciers create
hanging valleys
on which side of the dune does erosion occur
windward
on which side of the dune does deposition occur
leeward
what is it called when the removal of small particals by wind leaving heavier particals behind
deflation
when small particals are removed the remaining surface is called
dessert pavement
what does the shape and sizes of landforms due to wind depend on
wind speed
amount of time the wind blows
sediment supply
what are some land forms that are created by wave erosion
coastal cliffs
sea arches
sea stacks
what are some land forms that are created by wave erosion
coastal cliffs
sea arches
sea stacks
what are two examples of wave deposition
sand bars
sand spits
what is a sand bar
landforms that are parallel to the shoreline
what is sand spit
like sand bars but curve back to land in a hook shape
what can cause mass wasting
snow
heavy rains
earthquakes
human activity
what are the examples of mass wasting
mud flows
land slides
rock slides
