Science Test Chapter 3

  1. The effect of Earth’s rotation on the direction of winds and currents.
    Coriolis Effect
  2. An abnormal climate event that occurs every two to seven years in the Pacific Ocean, causing changes in winds, currents, and weather patterns for one to two years.
    El Nino
  3. The number of waves that pass a specific point in a given amount of time.
    Frequency

  4. A wall made of rock or concrete that is built outward from a beach to reduce erosion.
    Groin 
  5. The movement of sand along a beach.
    Longshore Drift
  6. A rush of water that flows rapidly back to sea through a narrow opening in a sandbar.
    Rip Current
  7. The total amount of dissolved salts in a water sample.
    Salinity
  8. The daily rise and fall of Earth’s waters on its coastline.
    Tide
  9. A giant wave usually caused by an earthquake beneath the ocean floor.
    Tsunami
  10. The movement of cold water upward from the deep ocean that is caused by wind.
    Upwelling
  11. The movement of energy through a body of water.
    Wave
  12. The vertical distance from the crest of a wave to the trough.
    Wave Height
  13. The horizontal distance between two wave crests.
    Wavelength 
  14. Describe two ways that waves can form
    Waves can form by the wind and earthquakes beneath the ocean.
  15. Explain what happens as a wave approaches the shore
    Near shore, wave height increases and wavelength decreases.
  16. Label the characteristic of a wave. 
    Wavelength, Crest, trough, wave height, frequency
  17. Explain how the motion of a wave is different than the motion of a current. 
    The motion of a wave is different because a current is a large movement of water in one direction,  a wave is a motion that moves water and energy from one area to another.
  18. Describe how tide occur.
    Tides are caused by the interaction of Earth,the moon, and the sun. 
  19. Illustrate the difference between spring tides and neap tides.

  20. Explain the location and cause of warm water currents and cold water currents.
    Warm currents start near the equator and cold currents start away from the equator.
  21. Discuss how ocean temperature, pressure, density, and light change with depth.
    • Temperature- Light doesn’t reach past 200 meters 
    • Pressure- The pressure increases by force exerted from the weight of all the water
    • Density- The water is most dense in the deep cold water because there is no warmth and there is more salinity
    • Light- The deeper you go the less light there is so the temperature drops and the water becomes more dense.
  22. List the gases found in ocean water that are needed by living things
    Two gases that living things use are carbon dioxide and oxygen.
