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.
