Presentation Transcript

  1. Continental Claciation Slide presentation

  2. Continental Glacier

  3. Outwash Plain - Large areas of glacial sediment deposited by glacial streams.

  4. Outwash Plain

  5. Horicon Marsh

  6. Glacial Drift Loose and unsorted rock debris distributed by glaciers and glacial melt waters. Two types: till and outwash

  7. Till – unsorted drift

  8. Outwash – glacial drift in layers

  9. Erratics – Large Boulders left behind by glaciers

  10. Moraines: a build up of sediment transported or left by the glacier

  11. Ground Moraine – sediment deposited under moving ice.

  12. End moraine - • Perpendicular to glacier • Dumps sediment at the edge of the glacier. • Marks the end of the glacier

  13. Northern Kettle Moraine -

  14. Devils Lake – End moraine

  15. Recessional Moraine • Sediment dumped by retreating ice

  16. Recessional moraine - Alps

  17. Inter-lobate Moraine • Kettle Moraine state forest is an example • Built between two lobes of ice.

  18. Kettle • Depressions on outwash plain that often fill with water. • Caused by stranded ice blocks and erosion

  19. Kettle

  20. Kettle

  21. Madison, WI

  22. Greenbush Kettle

  23. Esker • Look like inverted streams • Winding ridges of glacial drift deposited by melt-water in tunnels under the glacier • A stream under a glacier

  24. Esker

  25. Esker Parnell esker

  26. Kame • Cone shaped hill of sand and gravel;reverse funnel • Two types: • Delta – meltwater deposited sediments off the top of a glacier • Moulin Kame – base of a shaft through a glacier.

  27. Kame formation

  28. Drumlin • Look like upside down teardrops • Tapered end shows the direction the glacier moved in . • Formed from till

  29. Drumlin formation

  30. Drumlins in background

  31. Topographic map - drumlins

  32. Chatter Marks Rocks dragged by glacier left these marks

  33. Chatter marks

  34. Calving • calving glacier: glacier that loses material by calving, usually a glacier that terminates in sea, lake, or river water
