Glaciers Flashcards
Name the two types of glaciers
Alpine and continental
What are alpine glaciers
Glaciers move by gravity down the mountain side
What are continental glaciers
Glaciers that move under their own weight, the weight of the glacier caused it to spread out from the centre
How are glaciers formed
over thousands of years layers of snow will pile up and get deeper and deeper. The weight of the snow on top causes the bottom layers to turn to ice
What is the name of the ice sheet that covers Canada
The Laurentide Ice sheet
What is a glacial erratic
A rock that had been transported and deposited by the movement of a glacier
What are eskers
When meltwater rivers form on, within or under a glacier the sediment ls carried will be deposited somewhere along the river course. Over time they will build up and form a kind of hill over the river
What are drumlins
They are teardrop shaped hills formed from the movement of glaciers. They form in clusters where mixed loose loose sediments are able to be shaped
What are kettle lakes
They form when a chunk of ice is deposited when a glacier recedes
