What is the difference between a continental ice sheet and a valley glacier?
Continental glaciers form in a central location with ice moving outward in all directions. Alpine glaciers form in high mountains and travel through valleys. Ice caps cover large areas. Because glaciers move, they have characteristic features like crevasses and bergshrunds.
How are continental glaciers similar to valley glaciers?
Continental glaciers flow in all directions as they move, while valley glaciers move down slopes already cut by rivers. Valley glaciers cover much of a continent, while continental glaciers cover a small area of mountains. Continental glaciers are long and narrow, while valley glaciers are wider in size.
What is a valley glacier?
: a glacier usually originating in a cirque at a valley head or in a plateau ice cap and flowing downward between the walls of a valley.
What are the two types of glaciers How are they different?
Two kinds of glaciers are continental glaciers and valley glaciers. They are different because a continental glacier covers much of a continent and a valley glacier forms in a mountain valley. Snow builds the glacier’s weight compacting it forming ice and begins to move downhill. You just studied 15 terms!
Which is the longest valley glacier in the world?
The largest glacier in the world is the Lambert-Fisher Glacier in Antarctica. At 400 kilometers (250 miles) long, and up to 100 kilometers (60 miles) wide, this ice stream alone drains about 8 percent of the Antarctic Ice Sheet.
What is cirque called in Germany?
A cirque is knowns as in germany
What is the meaning of striation?
1a : the fact or state of being striated. b : arrangement of striations or striae. 2 : a minute groove, scratch, or channel especially when one of a parallel series. 3 : any of the alternate dark and light cross bands of a myofibril of striated muscle.
What is called cirque?
Cirque, (French: “circle”), amphitheatre-shaped basin with precipitous walls, at the head of a glacial valley. It generally results from erosion beneath the bergschrund of a glacier.
How can you tell a cirque?
Classic cirques take the form of armchair-shaped hollows (see image below), with a steep headwall (which often culminates in a sharp ridge, or arête) and a gently-sloping or overdeepened valley floor (see diagram below). Classic glacial cirque basin.
What is an example of a cirque?
The Eel Glacier on Mt. Anderson (Olympic National Park, Washington) is an excellent example of a cirque glacier. Cirque and alpine glaciers originate high in the mountains and flow downslope. They are called “cirque glaciers” if they originate in small bowls with steep headwalls (cirques).
