8 types of glaciers
Ice sheets I've caps Ice field Valley glacier Corrie glacier Piedmont glacier Niche glaciers Ice shelves
Example of ice sheets?
Antartica and Greenland
What shape is a ice cap?
Huge dome-shape
Where do ice caps develop?
High plateaus
What size are ice caps
<50000km3
What is a ice field?
Where much of an upland region is covered by glacial ice, just the taller peaks exposed (nunataks)
What is a valley glacier?
Larger masses of ice that flow from ice ice fields or corgis and usually follow preglacial river valleys
What do valley glaciers form
Developing steep sides as they erode their course
What are cirque glaciers?
Small ice masses on mountain slopes which gradually erode armchair shaped hollows.
What happens if a cirque glacier gets to large?
They spill over the lip to feed a valley glacier
What direction do cirque glaciers face?
N NE
What size ares do Corrie glacier face?
0.5 to 10 km2
What is a piedmont glacier
Large lobes of ice formed when glaciers spread out on reaching lowland areas and escaping the confines of the valley
How thick is the Antarctic ice sheet
Attains thickness of 4000m
