Glacial Geomorphology
Karten in diesem Stapel (9)
- 1—Till: assorted mixture of fine sediments of rock, sand, pebbles, and boulders deposited by a glacier
- 2—Outwash plains: any till that is deposited beneath or in front of a glacier and then picked up by subglacial water flow and redeposited beyond the glacier's farthest reach
- 3—braided river: drainage forced by excessive sediment that seek new pathways as old ones fill up
- 4—Moraines: ridges of till that accumulate along the edges of the glacier
- 5—Moraine Lakes: lateral and terminal moraines can impound water flowing from mountain drainage formally occupied by the glacier
- 6—Esker: very long depositional features left behind after glacial retreat, snaking across the landscape
- 7—Drumlins: till deposits, elongated but short ridges with their long axes parallel with former glacier movement
- 8—Kettle Lake: a block of ice is left behind and forms a lake
- 9—Erratic: large rocks, even boulders, that clearly differ markedly from the surrounding geology or any rock type one might expect in the vicinity
