Continental Glaciation
Karten in diesem Stapel (20)
- 1CreepIce pressure causes crystals to deform; squeezing causes move
- 2Basal SlipWater between ice and rock is formed by friction; Glacier moves rapidly
- 3ShearingIce tears as glaciers moves forward
- 4AbrasionRocks frozen to bottom of glacier scour rock
- 5QuarryingMelt water freezes in cracks of bedrock; chips away broken rock
- 6Rock Basin LakeLakes created from quarrying
- 7Bedrock PlainsExposed tracts of bedrock
- 8Finger LakesLong, skinny lakes scratched out of soft bedrock
- 9MorainesFormed when debris is pushed along bottom and sides of advancing ice; composed of glacial till
- 10Terminal MoraineFurthest extent of a moraine
- 11Lateral MoraineFormed on sides
- 12Interlobate MoraineWhere two ice sheets meet
- 13Recessional MoraineIce sheet retreats and advances (not as far as terminal point)
- 14Outwash PlainsStratified layers of alluvium deposits
- 15Kettle lakesLarge chunks of ice that did not completely melt become surrounded by glacial till
- 16SpillwaysMeltwater collects in large streams and channels; water carves out valleys in till
- 17EskersRivers on top, inside, and under glaciers carry sediments; Glacier melts, sediments deposited in long line
- 18KameGlacial delta at end of stagnant glacier
- 19DrumlinsLike smaller moraines; Ice piles in front, then 'jumps' to create smooth sides hill
- 20StriationsScratches in bedrock
