glacier flashcards
Abrasion
Erosion caused by big rocks at the base of a glacier which scrape underneath the glacier
Arete
A sharp ridge formed between two corries cutting back by processes through of erosion and freeze thaw action
Corrie
valley-like slope formed by glacial erosion where a valley glacier begins
Conservation
Managing the environment in order to preserve and restore it
Bulldozing
ice glaciers pushing objects in its path
Drumlin
a mound made by deposited glacial till
Erratics
rocks deposited by glacier far from where they started
Feeze-Thaw weathering
water enters cracks in rocks, and then freezes, therefore expanding, causing pieces of rock to fall off.
Glacial trough
A river valley eroded into shape by a glacier: U-shaped rather than V-shaped
Hanging valley
A tributary valley to the main glacier, too high & cold to be fully eroded.
land use conflicts
disagreements on how land should be used
Moraine
Rock debris and eroded material eroded from the valley floor, deposited by glacier.
Outwash
Material, mostly sand/gravel left by melt water underneath a glacier
Plucking
where melt water freezes on rocks under a glacier, and takes chunks of rock off when the glacier moves
Pyramidal peak
Where corries cut back & meet at a point
