Glaciers
Parts of glaciers:
zone of accumulation; zone of wastage, melting, sublimation/evaporation, calvingTypes of glaciers:
valley glaciers (alpine glaciers), continental ice sheetsErosion
: plucking; abrasion, striations, polishing, rock flourTransport:
in the ice, on the ice, on edges/front, in meltwaterDeposition:
till - poorly sorted, large grain size, angular fragments; moraines, end moraines,lateral moraines, medial moraines, ground moraines, glacial erratics; stratified drift, fine-grained, well sorted, varvesAlpine Landforms:
U-shaped valleys, cirques, horns, aretes, moraines
Explain the mechanisms by which a glacier loses material in the zone of wastage.
Compare and contrast till and stratified drift. What is a moraine? How do ground moraines differ from the other types of moraines?
Be prepared to define and/or identify the various alpine landforms carved by glaciers.
