1
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”
2
Mechanical Weathering
Erosion Mechanical Weathering Water: Rivers Chemical Weathering Water: Groundwater Rate of Weathering Water: Waves Soil Water (Ice): Glaciers Soil Horizons Wind
3
Weathering Define “weathering”
Actions: particles created by weathering are Carried away by erosion, or Form soil
4
Mechanical Weathering
Define “Mechanical Weathering” Types (define each) Release of pressure Freezing and thawing (ice wedging) Animal actions Plant growth Abrasion
5
Chemical Weathering Define “Chemical Weathering” Types (define each):
Water (H2O) Oxygen (O2, oxidation) Carbon Dioxide (CO2) Living organisms Acid rain
6
Rate of Weathering Define how each affects rate (speed) Surface area
Type of rock (permeable, nonpermeable) Climate Human activities
7
Soil Define: How do scientists classify different soil types?
Soil (what is soil made of?) Bedrock Humus Fertility Loam Litter Decomposers sod How do scientists classify different soil types?
8
Soil Horizons Draw a soil horizon diagram and define what is in each layer A Horizon B Horizon C Horizon Bedrock (D Horizon)
9
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?
10
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)
11
Water Erosion: Groundwater
Define: Groundwater Cave, stalactite, stalagmite Karst topography Drawing a small cave diagram is a good idea (but optional)
12
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?
13
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
14
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)
