Unit 6 Earth Science
the process by which glaciers cut, carve or scratch the earth's surface
a narrow, wedge-shaped mass of ice that forms in a small mountainous region
huge slabs of ice and snow that cover large areas of land for thousands of years
a glacier that spreads out from a central mass of ice
a large mass of ice floating at sea
A type of glacial movement that occurs within the glacier, below a depth of approximately 50 meters, in which the ice is not fractured.
Zone of Fracture
uppermost portion of glacier
A deep crack or fissure in the ice of a glacier.
a deep, U-shaped valley carved by an alpine glacier.
a sharp narrow ridge found in rugged mountains
glaciers curve away the sides of a mountain the result is this a sharened peak
A valley left by a melted tributary glacier that enters a larger glacial valley above its base, high up on the valley wall.
a steep-walled semicircular basin in a mountain
a mountain lake (especially one formed by glaciers)
Pater Noster Lakes
lakes that looked like rosary beads
glacial deposit that has been sorted and layered by the actions of streams or meltwater
large boulders that have been plucked and transported a great distance before they are deposited
eroded rock material dropped at the front of a glacier
moraine that forms along the sides of glaciers
are formed when two advancing valley glaciers come together to form a single ice stream
a technique that climbers use to stop from falling down a slope by digging an ice ax into the snow
the mixture of sediments that a glacier deposits directly on the surface
area in front of a glacier in which melt water from the glacier has carried & deposited an abundance of sorted material
a mound of glacial drift
large block of ice that falls off a glacier and melts, forming a hole then filling with water
