Introduction to Glaciology

Glacial flow is the movement of glaciers due to the force of gravity and the pressure exerted by the weight of the ice.

Ice caps are not glaciers, but rather large masses of ice that cover a large area of land.

Ablation is the process by which glaciers lose mass through melting, sublimation, and evaporation.

Glacier retreat can lead to decreased water quality due to the release of sediment and contaminants that were previously trapped in the ice.

Calving is the process by which glaciers break off into smaller pieces, typically at the terminus of the glacier.

Strong winds are not a factor that contributes to glacier formation.

The equilibrium line is the line that separates the area of accumulation from the area of ablation on a glacier.

Recessional moraines are not a type of glacial moraine.

Glacial erosion is the process by which glaciers erode the underlying bedrock through abrasion, plucking, and quarrying.

Glacier advance can lead to decreased water quality due to the release of sediment and contaminants that were previously trapped in the ice.

Crevassing is the process by which glaciers form crevasses, which are deep cracks in the ice.

Loess is not a type of glacial deposit.

Glacial transport is the process by which glaciers transport sediment through erosion, transportation, and deposition.

Glacier melting can lead to decreased water quality due to the release of sediment and contaminants that were previously trapped in the ice.

Glacial deposition is the process by which glaciers deposit sediment through melting, sublimation, and evaporation.
