Geography 12

2. What is a glacier?
What are the two main types of glaciers?
How do glaciers form?

3. What is a glacier?
A glacier is simply the existence of year-round ice on the landscape.
There are two broad types: ____________________ and ____________________.
How do glaciers form?
Glaciers form whenever snowfall exceeds snowmelt year after year. The snow accumulates incrementally, pressure increases, and it is changed into
névé: _________________________ and then ice by this pressure.

4. Maximum Extent of Pleistocene Glaciation - 1/3 of land surface
Most recent glacial maximum peaked 18,000 years ago and is considered to have ended 10,000 B.P.

6. Q: Why is a glacier the only thing that is ever coming and going at the same time?

7. Erosion by Glaciers Photo above: What are these stripes called?
volume and speed determines amount of erosion
erodes slightly more effectively than water
plucking and abrasion
polishing and striations
Continental glaciers remove all soil, plants, and small hills
Alpine glaciers change V-shaped valleys to U-shaped
Photo above:
What are these stripes called?
What causes them

8. Erosion at work

10. Transportation by Glaciers:
Will move material of all sizes, from glacial flour to massive boulders
Slow transport
Water in, on, and under glaciers (pluvial processes) moves much sediment as well

11. Deposition by Glaciers
Drift is any material deposited by glaciers or their melt water.
Till is that unsorted material that is deposited directly by ice.
_______________are linear features deposited at bottom or along sides of glaciers.
Glacial ______________ is an enormous boulder transported and deposited by glaciers, often far from their source region.

12. Alpine Glaciation (Mt. Rainier, Washington)

15. Moraines

17. Moraines in Yukon, Whitehorse

18. Continental Glaciers or Ice Sheets
only two true ice sheets exist today: Greenland and _____________________
where they meet the sea they can form ice sheets.
vary in thickness from hundreds of feet to ______ miles deep
________________ away all soil and vegetation and dramatically reshape the landscape and ecology of large regions
Ellesmere Island, Canada
