1. Glaciers

2. A GLACIER forms when yearly snowfall in a region far exceeds the amount of snow and ice that melts during the summer months. Most of the world's glaciers are found near the Poles, but glaciers exist on all of the world's continents, even Africa. Only, Australia doesn't have any glaciers!

3. Types of Glaciers Glaciers can be characterized in two ways based on their formation: alpine and continental. Alpine Glacier - Most glaciers that form in a mountain are known as alpine glaciers. Continental Glacier – An expansive, continuous mass of ice considerably bigger than an alpine glacier is known as a continental glacier.

6. Glaciers and the Environment http://dsc.discovery.com/videos/discovery-project-earth- jakobshaven-glacier-retreat.htmlhttp://dsc.discovery.com/videos/discovery-project-earth- jakobshaven-glacier-retreat.html The common fear is that with temperatures rising worldwide, glaciers will begin to melt, releasing some or all of the huge amounts of water held inside. As a result, the oceanic processes and structures we have adapted to will abruptly change, with unknown consequences. To find out more, scientists are turning to paleoclimatology, a field of study that uses glacial deposits, fossils, and sediments to determine the history of earth's climate. Ice cores from Greenland and Antarctica are currently being used to this end. http://dsc.discovery.com/videos/discovery-project-earth-wrapping- glaciers-in-a-nutshell.htmlhttp://dsc.discovery.com/videos/discovery-project-earth-wrapping- glaciers-in-a-nutshell.html

7. Continental Glacial Land Formations

8. Drumlins Glacial moraine (sand, silt, pebbles, boulders,…) that’s dumped. Therefore it’s unsorted material (all different sizes)

11. Glacial Streams - can wash away sand and small rocks, - aren’t powerful enough to wash out bigger material (ie. boulders)

15. Eskers Long, sandy hills that snake through the landscape Were once glacial streams that filled with sand.

18. Erratics As they moved forward, ice sheets often picked up large rocks and carried them hundreds of kilometres They can be identified because they are made of rock which is different from the bedrock of the region in which they are deposited

21. Erratic: How did this rock get like this?

28. Kettle Lakes Kettle Hole –Depression found in glacial deposits. Created when a piece of ice from a retreating glacier becomes embedded in soft glacial till or glacial drift deposits. Many are filled with water to form a small lake or pond.glacialglaciertill glacial driftlake

30. Moraine- a ridge of till, deposited at the edge of a retreating ice sheet

31. The Oak Ridge Moraine

36. Striations Formed by erosion retreating glaciers contain a lot of debris, this is dragged across the surface of rocks leaving lines in the bedrock

40. Alpine Glacier Land Formations

41. Arête- is a sharp ridge between cirques

43. Horns- pyramid shaped peaks

44. Cirque- Glacially eroded rock basin found on mountains. Most alpine glaciers originate from a cirque.

45. U- Shape Valley, because it has steep sides and a nearly flat floor.

46. Fjords-A glacial valley or glacial trough found along the coast that is now filled with a mixture of fresh water and seawater.
