Weathering & ErosionFoldable • No notebooks on quiz, but you will be able to use this foldable • 6-Door Foldable • Take 3 pieces of paper • Offset them 2 inches “hotdog” style • Fold over to create six “doors”
Weathering • Define “weathering” • Actions: particles created by weathering are • Carried away by erosion, or • Form soil
Mechanical Weathering • Define “Mechanical Weathering” • Types (define each) • Release of pressure • Freezing and thawing (ice wedging) • Animal actions • Plant growth • Abrasion
Chemical Weathering • Define “Chemical Weathering” • Types (define each): • Water (H2O) • Oxygen (O2, oxidation) • Carbon Dioxide (CO2) • Living organisms • Acid rain
Rate of Weathering • Define how each affects rate (speed) • Surface area • Type of rock (permeable, nonpermeable) • Climate • Human activities
Soil • Define: • Soil (what is soil made of?) • Bedrock • Humus • Fertility • Loam • Litter • Decomposers • sod • How do scientists classify different soil types?
Soil Horizons • Draw a soil horizon diagram and define what is in each layer • A Horizon • B Horizon • C Horizon • Bedrock (D Horizon)
Erosion • Define: • Uniformitarianism • Erosion • Deposition • Gravity • Mass movement • Landslides, mudflows, rockfalls, slump, creep • How do weathering, erosion, and deposition interact (work together)? • What type of erosion forms a v-shaped valley? What type forms a u-shaped valley?
Water Erosion: Rivers • Define: • Runoff • River features: • Rill, gully, stream, tributary, waterfall, flood plain, valley, meander, oxbow lake, alluvial fan, delta • Drawing a small river system diagram is a good idea (but optional)
Water Erosion: Groundwater • Define: • Groundwater • Cave, stalactite, stalagmite • Karst topography • Drawing a small cave diagram is a good idea (but optional)
Water (Ice) Erosion: Glaciers • Define: • Two types: continental glacier, valley glacier • Ice age • Plucking • Till • Glacier features: moraine, kettle, cirque, horn, fiord, arete, drumlin, u-shaped valley, glacial lake • Drawing a glacier diagram is a good idea (but optional • How do glaciers form, and then move?
Water Erosion: Waves • How do ocean/lake waves form? • How do waves erode the land? • Define: • Shore features: headland, wave-cut cliff, sea stack, sea cave, sea arch, beach, spit, sandbar, barrier beach • Longshore drift
Wind Erosion • How does wind erode land? • Define: • Deflation • Abrasion • Loess • Sand dune • Drawing a diagram of wind erosion is a good idea (but optional)
