Weathering & Erosion Foldable
- 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
Soil Horizons
- How do scientists classify different soil types?
- 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: longshore drift
- Shore features: headland, wave-cut cliff, sea stack, sea cave, sea arch, beach, spit, sandbar, barrier beach
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)
