Show Answers:

  1. What are the 4 causes of evolution? 
    • 1. Natural Selection 
    • 2. Genetic Drift 
    • 3. Gene Flow
    • 4. Mutations
  2. Name the 3 types of biodiversity:
    • 1. Genetic diversity (# of genetic characteristics)
    • 2. Species diversity (the # of different species)
    • 3. Habitat diversity (provides different environments)
  3. Name the two Aeolian erosional processes.
    • 1. Deflation = the removal and lifting of individual loose particles
    • 2. Abrasion = grinding of rock surgaces by particles in the air ('sandblasting')
  4. T/F: Most of the earth's deserts are made up of mostly sandy consistencies. 
    False; most deserts are made up small rock or gravel called desert pavement. 
  5. Name the 5 different dune types:
    • 1. Barchan: limited sand 
    • 2. Transverse: forms in abundant sand, very little vegetation
    • 3. Parabolic: vegetation controlled
    • 4. Longitudinal: narrow, sharp-crested
    • 5. Star: mulitiple slip faces, radiating armes and changing wind patterns.
  6. What type of sand dune is this?
  7. What type of dune is this? 
    Transverse dune
  8. What type of dune is this? 
    Parabolic-has sand but controlled vegetation
  9. What type of dune is this?
    Longitudinal dune
  10. What type of dune is this?
    Star dune
  11. How do soils form? Pneomonic device: CROPT
    Climate Relief Organisms Parent material Time
  12. What global region has the highest net primary production?
    Tropical rainforests
  13. Name the five different biomes and rank them as 1 being the most moist to 4 being the dryest:
    • 1. Tundra
    • 2. Grasslands (3)
    • 3. Deserts (4)
    • 4. Forests (2)
    • 5. Aquatic (1)
  14. What are limiting factors to primary production? 
    • 1. light
    • 2. temperature
    • 3. water
    • 4. salinity 
    • 5. nutrients
  15. T/F: The ocean is very limited in its CO2 supply.
    False; is a sink for CO2
  16. If ablation of a glacier is greater than accumulation, the glacier will: 
    Retreat or become smaller
  17. What proces erodes and transports material in glaciers?
  18. What happens to waves when the depth of the ocean becomes shallow?
    Wave height increases until waves break. 
  19. Which of the following is a glacial depositional feature? 
    A. cirque
    B. arete
    C. hanging valley
    D. moraine
    D. Moraine - deposits left over from a glacier
    (this multiple choice question has been scrambled)
  20. Which of the following is NOT evidence of past glaciation?
    A. talus below a rocky cliff
    B. glacial erratics
    C. striations in bedrock
    D. glacial polish on bedrock
    A. Talus below a rocky cliff
    (this multiple choice question has been scrambled)
  21. T/F: Waves carry water molecules from the middle of oceans to coastlines.
  22. T/F: Glaciers erode, transport, and deposit only small-sized sediment (silt and till).
    False, they carry all types of deposits such as rocks, boulders, etc. 
  23. What type of weather is likely to be dominant in cold, glaciated regions? 
    Physical weathering
  24. What is the equation for respiration?
  25. What is the equation for photosynthesis?
