Study Notes
Valley Glaciers
- Form in mountain valleys from the accumulation of snow and ice.
- Characterized by a long and narrow shape.
Geographical Features
- Arete: A narrow, jagged ridge created by the erosion of two adjacent glacier valleys or cirques.
- Cirque: A bowl-shaped basin formed by glacial erosion, often found at the head of a valley.
- Horn: A pointed mountain peak, typically with a pyramidal shape, formed by the convergence of multiple cirques.
Glacial Lakes and Landforms
- Glacial Lake: Large lakes left in long basins after glaciers retreat.
- Kettle Lake: Small lakes that form in depressions created by melting ice chunks left in sediment.
- Moraine: A ridge composed of till, formed from materials deposited at the edges of a glacier.
- Drumlin: An elongated hill of till shaped by the direction of glacier flow.
Valley Morphology
- U-shaped Valley: Created when a glacier erodes the landscape, resulting in a distinctive U shape.
- Fiord: Coastal valleys submerged by rising sea levels after being carved by glacial activity.
Ice Age
- Defined as any historical period when glaciers covered significant portions of the Earth’s surface.
