Study Notes
Coastal Erosion by Waves
- Waves erode coastlines by breaking down rock, moving sediments, and impacting rocks with force.
- Waves enlarge cracks in rocks, causing pieces to break off.
- Abrasion is another way waves break apart rocks.
Glacial Landforms
- Glaciers carve landforms through erosion and deposition.
- Cirque: A bowl-shaped hollow eroded by a glacier.
- U-shaped valley: A valley scooped out by a flowing glacier.
- Arete: A sharp ridge separating two cirques.
- Kettle lake: Forms when a depression left by melting ice fills with water.
- Horn: A sharpened mountain peak formed by glaciers eroding its sides.
- Moraine: A ridge formed by glacial till deposition.
- Fjord: A valley filled with rising sea levels after a glacier's retreat.
- Till: The mixture of sediments (clay, silt, sand, gravel, boulders, rock flour) deposited directly by a glacier.
