2 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

11

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

29 Kettle Lake: Forms when melting ice forms a depression in till and it fills with water No water = Kettle Deposition
