  1. Define
    Current
    A giant stream
  2. Define Surface Current
    A giant stream of water near the ocean surface
  3. Define Deep Current
    A giant stream of water near the bottom of the ocean
  4. Define Coriolis Effect
    The curving of currents due to Earth’s rotation
  5. Define Trade Winds
    Major wind belts that blow currents westward by the equator

  6. Define Westerlies
    Major wind belts that blow currents eastward in the middle latitudes
  7. Define Upwelling
    When deep, cold, nutrient-rich water rises to the surface
  8. Define Breaker
    When the top part of a wave “breaks” off because the bottom part of the wave drags along the ocean floor
  9. Define Refraction
    The bending of a wave because shallow waves slow down, but deeper waves do not
  10. Define Undertow
    When waves pull back (strongly) into the ocean
  11. Define Rip Current
    A STRONG current perpendicular to the shore
  12. Define Longshore current
    A current parallel to the shore
  13. Define Tsunami
    A giant wave caused by an oceanic earthquake
  14. Define Tide
    The rise & fall of the ocean’s water level caused by the gravitational pull of the moon
  15. Define Density
    How much mass per volume there is
  16. Explain how a surface current forms.
    Wind gives a lot of energy to ocean water and over time creates a current
  17. Explain how a deep current forms.
    Cold, dense water sinks and over time creates a current
  18. How do wind patterns affect surface currents?
    The wind blows the currents in different directions
  19. How does Earth’s rotation affect surface currents?
    Earth’s rotation curves currents (Coriolis Effect)
  20. How do continents affect surface currents?
    Currents get reflected & split by continents
  21. How do surface currents distribute energy around the world?
    Surface Currents carry warm water away from the equator; thermal/heat energy
  22. How do deep currents distribute energy around the world?
    Deep Currents carry cold water towards the equator; thermal/heat energy
  23. How does water move in a wave?
    Water moves in a circle as the wave passes. The surface receives more energy than the bottom.
  24. How does the speed of wind affect wave size?
    More speed = More energy = Bigger wave
  25. How does the length of time wind blows affect wave size?
    More time = More energy = Bigger/More waves
  26. How does the distance of the wind affect wave size?
    More distance = More energy = Bigger waves
  27. Explain what happens to a wave when it approaches a coastline.
    The wave will bend & break.
  28. Which way do currents move in the Northern hemisphere because of the Coriolis Effect?
    East
  29. Which way do currents move in the Southern hemisphere because of the Coriolis Effect?
    East
