Till - correct answer ✔unsorted sediment deposited directly by a glacier
Cirques (corries) - correct answer ✔Created by glaciers grinding an existing valley into a Rounded shape
with steep sides
Occurs when meltwater penetrates the cracks and joints of bedrock beneath a glacier and freezes -
correct answer ✔Plucking
The grinding and scraping of a rock surface by the friction and impact of rock particles carried by water,
wind, and ice. - correct answer ✔Abrasion
A small lake in a cirque - correct answer ✔Tarn
A narrow, knifelike ridge separating two adjacent glaciated valleys. - correct answer ✔Arête
A pass between mountain valleys where the head- walls of two cirques intersect. - correct answer ✔Col
A pyramid-like peak formed by glacial action in three or more cirques surrounding a mountain summit. -
correct answer ✔Horn
During glaciation, an alpine glacier widens, deepens, and straightens the valley, creating a - correct
answer ✔U-Shaped Valleys
As ice flows around sharp curves, its great erosional force removes the spurs of land that extend into the
valley. The results of this activity are triangular-shaped cliffs called - correct answer ✔Truncated Spurs
,A tributary valley that enters a glacial trough at a considerable height above the floor of the trough. -
correct answer ✔Hanging Valley
Glacial Valleys which have been inundated by the sea (i.e. a drowned U-Shaped Valley) - correct answer
✔Fjords
A chain of small lakes in a glacial trough that occupies basins created by glacial erosion. - correct answer
✔Pater Noster Lakes
Erosion resulting from glacial action, whereby the material surface is removed and the rock fragments
carried by the glacier abrade, scratch, and polish the bedrock - correct answer ✔Glacial Scour
(Scouring)
Scratches or grooves in a bedrock surface caused by the grinding action of a glacier and its load of
sediment. - correct answer ✔Striation
Layers or ridges of till (unsorted glacial deposits) deposited from glacial ice - correct answer ✔Moraines
A ridge of till along the sides of a valley glacier composed primarily of debris that fell to the glacier from
the valley walls. - correct answer ✔Lateral Moraine
A ridge of till formed when lateral moraines from two coalescing alpine glaciers join. - correct answer
✔Medial Moraine
The end moraine that marks the farthest advance of a glacier. - correct answer ✔Terminal Moraine
An undulating layer of till deposited as an ice front retreats. - correct answer ✔Ground Moraine
, A streamlined symmetrical hill composed of glacial till. The steep side of the hill faces the direction from
which the ice advanced. - correct answer ✔Drumlin
A sinuous ridge composed largely of sand
and gravel deposited by a stream flowing in a tunnel beneath a glacier near its terminus. - correct
answer ✔Esker
Depressions created when blocks of ice become lodged in glacial deposits and subsequently melt. -
correct answer ✔Kettle Holes
A steep-sided hill composed of sand and gravel, originating when sediment collected in openings in
stagnant glacial ice. - correct answer ✔Kame
A relatively flat, gently sloping plain consisting of materials deposited by melt-water streams in front of
the margin of an ice sheet. - correct answer ✔Outwash Plain
