Study Notes
Erosion and Related Processes
- Erosion: A process that wears away surface materials and transports them to different locations.
- Deposition: Occurs when erosion agents drop sediments as they lose energy, leading to sediment accumulation.
- Mass Movement: Involves erosion processes where gravity causes materials to move downslope.
Types of Mass Movement
- Slump: A type of mass movement where material slips down a curved surface, characterized by distinct features.
- Creep: A slow, gradual process where sediments shift downhill over time.
Glacial Movement and Effects
- Glacier: A significant mass of ice and snow that moves over land, impacting the landscape.
- Plucking: A glacial process where ice and meltwater infiltrate rock cracks, freeze, and fracture the rock, prompting erosion.
- Till: Refers to a heterogeneous mixture of sediment sizes, typically left behind by glacial activity.
- Moraine: A prominent ridge formed by the accumulation of debris pushed along by glaciers, resembling a bulldozer's path.
- Outwash: Sediments deposited by glacial meltwater, commonly found beyond the glacier's terminus.
Wind Erosion
- Deflation: A wind erosion process that removes small particles from loose sediment, altering the landscape.
- Abrasion: Occurs when windblown sediments strike rock surfaces, leading to physical wear and tear.
- Loess: Refers to wind-blown deposits of fine sediments, contributing to soil formation in various regions.
- Dune: A natural mound formed by the accumulation of sediments that have been shifted by wind action.
