The flashcards below were created by user nanananako on FreezingBlue Flashcards. What would you like to do?


  1. isolated system
    don't exchange matter or energy
  2. closed system
    exchange of energy but not matter
  3. open system
    can exchange energy and matter
  4. negative feedback
    • regulator
    • response opposite from output
  5. positive feedback
    • amplifier
    • output increases output
  6. input, output, and climate relation
    • input = output --> stable climate
    • input > output --> warming climate
    • input < output --> cooling climate
  7. 1st law of thermodynamics
    energy neither created or destroyed
  8. 2nd law of thermodynamics
    entropy
  9. 7 major plates
    • African
    • North American
    • South American
    • Eurasian
    • Australian-Indian
    • Antarctic
    • Pacific
  10. 4 minor plates
    • Nazca
    • Cocos
    • Caribbean
    • Juan de Fuca
  11. Pangaea
    • N: Laurasia
    • S: Gondwanaland
  12. declination
    taking account that magnetic north is different from geographic north
  13. inclination
    if you're not at the magnetic equator, your magnet dips
  14. classic model of Earth's internal structure
    • crust: 0-100km
    • mantle: 100-350km
    • liquid outer core
    • solid inner core
  15. tectonic model of Earth's internal structure
    • lithosphere
    • asthenosphere
    • mesosphere
    • liquid outer core
    • solid inner core
  16. mantle plume
    • small magma source
    • Hawaii, Yellowstone
  17. divergent plate boundaries
    moving away from each other
  18. shallow earthquakes occur in
    plate boundaries
  19. deep earthquakes associated with
    trenches
  20. viscosity
    resistance to flow
  21. strike, focus, and epicenter (faults)
    • strike: map view direction
    • focus: where the energy was released
    • epicenter: location on the map
  22. strike-slip/transform/shear faults
    • adjacent blocks translate horizontally past one another
    • right lateral: clockwise
    • left lateral: counter-clockwise
  23. thrust/reverse fault
    hanging wall thrust over the foot wall
  24. normal/dip-slip fault
    hanging wall goes down
  25. body waves
    elastic deformation
  26. primary waves
    • slinky
    • compressional
  27. secondary wave
    • shearing
    • rope
    • only passes through solids
  28. surface waves
    • only passes through the surface of the earth and is slower
    • Love waves
    • Rayleigh waves
    • sound waves and tsunamis
  29. Love waves
    near the surface of the earth
  30. Rayleigh wave
    • combination of compression and shearing
    • most destructive
  31. 3 ways to magnitude of earthquakes
    • magnitude
    • Richter scale
    • Mercalli (qualitative)
  32. liquefaction
    quick sand
  33. trough firs
    appear as a strong withdrawal of water
  34. crust fist
    appear as a strong increase of water
  35. stratovocano
    • steep, conical
    • Mt. Fuji
  36. tephra cones
    • Mt. Etna
    • extremely explosive
  37. shield volcanoes
    • gently sloped and dome shaped
    • not explosive
    • Hawaii
  38. caldera
    volcano that collapsed
  39. plutons
    solidified lava in the ground
