Glacier Formation and Movement

Study Notes

Glacier Formation and Characteristics

Water vapor condenses and falls as snow over mountain ranges due to the orographic effect, where air is forced to rise, cool, and condense, resulting in precipitation.

Types of Glaciers

A glacier is defined by its continuous flow and deformation under its own weight.
Valley glaciers are confined to a specific valley or mountain range.
Piedmont glaciers are formed when a valley glacier flows out of a mountain range and onto a plain, where it spreads out and becomes wider.
Unconfined glaciers are not limited by surrounding terrain and can flow freely in any direction.
Alpine glaciers originate as one or more cirque glaciers, then flow down the valley as they accumulate mass, grow, and join others.
Cirque glaciers are formed in a cirque, a natural amphitheater-shaped valley, and are characterized by their small, circular shape.
Piedmont glaciers can be distinguished from ice sheets by their smaller size and more irregular shape.
Ice sheets are large, continuous sheets of ice that cover a vast area of land.
Glaciers deform under their own weight if they are thick enough or on a steep slope, causing the ice to creep and flow.
