Glacier: Any large mass of ice that moves slowly over land
3
VALLEY GLACIER:CONTINENTAL GLACIER:
4
Valley Glacier: A long, narrow glacier that forms when snow and ice build up in a mountain valley - Found on high mountains - Stay in valley/follow valley
5
Continental Glacier: A glacier that covers much of a continent or large island - Larger than valley glaciers - Spread out in all directions
6
Ice Ages: Times in the past when continental glaciers covered large parts of Earth’s surface
7
Ice Ages: Times in the past when continental glaciers covered large parts of Earth’s surface
8
Form where more snow falls than melts Pressure compacts snow into ice Gravity pulls glacier downhill
9
PLUCKING The process by which a glacier picks up rocks as it flows over the land ABRASION Rocks stick to the bottom of glacier, scrape across the land, and scratch bedrock
10
Till: The sediment deposited by a glacier
12
Fjord: A glacial valley filled with seawater Erosion
13
Fjord: A glacial valley filled with seawater Erosion
14
Horn: A sharpened peak on top of a mountain – glaciers have carved away the sides Erosion
15
Horn: A sharpened peak on top of a mountain – glaciers have carved away the sides Erosion
16
Cirque: A bowl- shaped hollow area eroded by a glacier Erosion
17
Cirque: A bowl- shaped hollow area eroded by a glacier Erosion
18
Arête: A sharp ridge separating two cirques Erosion
19
Arête: A sharp ridge separating two cirques Erosion
20
Glacial Lake: A long lake, eroded by plucking and abrasion Erosion
21
Glacial Lake: A long lake, eroded by plucking and abrasion Erosion
22
U-Shaped Valley: Shape of a valley created by a glacier Erosion
23
U-Shaped Valley: Shape of a valley created by a glacier Erosion
24
Moraine: A ridge formed by the till deposited at the edge of a glacier Deposition
25
Moraine: A ridge formed by the till deposited at the edge of a glacier Deposition
26
Drumlin: A long mound of till that is smoothed in the direction of a glacier’s flow Deposition
27
Drumlin: A long mound of till that is smoothed in the direction of a glacier’s flow Deposition
28
Kettle Lake: Forms when melting ice forms a depression in till and it fills with water No water = Kettle Deposition
