17
Q

what is a cirque

A

a bowl shaped basin

18
Q

how do aretes form

A

form where two adjacent valley glaciers meet and erode a long, sharp ridge line

19
Q

what are horns

A

sharpened peaks

20
Q

what shape of valleys do valley glaciers create

A

U-shaped valleys

21
Q

what is a tribuatary glacier

A

small glaciers that feed into large glaceriers

22
Q

what type of valleys do tributary glaciers create

A

hanging valleys

23
Q

on which side of the dune does the erosion occur

A

the windward side

24
Q

on which side of the dune is sediment deposited

A

the leeward side

25
Q

what is it called when the removal of small particles by wind, leaving heavier particles behind

A

deflation

26
Q

what is called when all the small particle are removed and there is only hard surface left behind

A

desert pavement

27
Q

what does the shape and sizes of land forms due to wind depend on

A

wind seed, amount of time the wind blows, and sediment supply

28
Q

what are land forms that are created by wave erosion

A

coastal cliffs, sea arches, and sea stacks

29
Q

what are two examples of wave position

A

sand bars and sand spits

30
Q

what is a sand bar

A

land forms that are parallel to the shoreline

31
Q

what are sand spits

A

sand bars that extend into the water from land and curve back toward land in a hook shape

32
Q

what can cause mass wasting

A

can be caused by snow, heavy rains, earthquakes, or human activity

33
Q

what are examples of mass wasting
