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)
