Glaciers

First year glacial snow

Accumulated snow that has survived one melt season

Slope of bedrock surface, internal deformation, and basal meltwater

The depletion of ice from the glacier

The difference between accumulation levels and ablation

Three parameters of the earth's rotation that causes glacial fluctuations

The smallest and forms in a small bowl shaped depression in the mountains

Flows through valleys in the mountains

When valley glaciers flow out onto an adjacent plain

Hundreds of square miles of glaciation

Glaciers that occupy valleys that extend below the coverage of ice field

When glaciers end up reaching the sea and terminate at the shoreline

Bodies of freshwater that are contained deep within the layers of ice sheets

Top end of a glacier

Downhill end

A large mass of debris that marks the glaciers furthest advance

Where snow melts in the summer

Where snow lasts all year

Separates the zone of abiation from the zone of accumulation

Any ridge or mound of glacial debris that is deposited in glaciated regions

Ridges that are behind the terminal moraine

Material that has been pushed off to the side of glaciers

Form when two glaciers converge

The layer of till and other sediments underneath a glacier

Accumulations of debris on top of glacial ice

Picking up of loose material by the glacier from along the bed and valley sides

Thought to be made by glaciohydraulic supercooling (a process that allows water at the base of a glacier to remain liquid at a temperature below its freezing point in response to the geometry of water flow and subglacial pressure)

Involves the glacier freezing onto the valley sides and subsequent ice movement pulling away masses of rock

Carried on the surface of the glacial as lateral and medial morraines

Surface melt water carries a small load and this often disappears down crevasses

Sediment carried within the body of the glaier

Marks the farthest extent for the glacier

Debris deposited directly by a glacier
