What is the main difference between a continental glacier and a valley glacier?
Glacial ice flows away from the zone of accumulation when the thick ice deforms plastically under its own weight. In a valley glacier the ice flows downslope from the zone of accumulation, while for a continental glacier the ice flows laterally outward and away from the zone of accumulation.
What is the difference between continental and alpine glaciation?
Continental glaciers form in a central location with ice moving outward in all directions. Alpine glaciers form in high mountains and travel through valleys. Ice caps cover large areas. Because glaciers move, they have characteristic features like crevasses and bergshrunds.
Why are glacial valleys shaped differently from river valleys?
Valley glaciers carve U-shaped valleys, as opposed to the V-shaped valleys carved by rivers. As glaciers flow through these valleys, they concentrate erosive action over the entire valley, widening its floor and over-steepening its walls.
Which feature is not formed by glacial erosion?
Which feature is not formed by glacial erosion? Col. Hanging valley. Moraine.
What landforms are created by glacial erosion?
The landforms created by glacial erosion are:
- Corries.
- Arêtes.
- Pyramidal Peaks.
- U Shaped Valleys or glacial troughs.
- Truncated Spurs.
- Hanging Valleys.
What are 2 types of glaciers that help create landforms on Earth?
Glacier Landforms
- U-Shaped Valleys, Fjords, and Hanging Valleys. Glaciers carve a set of distinctive, steep-walled, flat-bottomed valleys.
- Cirques.
- Nunataks, Arêtes, and Horns.
- Lateral and Medial Moraines.
- Terminal and Recessional Moraines.
- Glacial Till and Glacial Flour.
- Glacial Erratics.
- Glacial Striations.
What is glacial action?
All processes due to the agency of glacier ice, such as erosion, transportation, and deposition. The term sometimes includes the action of meltwater streams derived from the ice.
