Science Test Chapter 3

 The effect of Earth’s rotation on the direction of winds and currents. Coriolis Effect 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 The number of waves that pass a specific point in a given amount of time. Frequency A wall made of rock or concrete that is built outward from a beach to reduce erosion. Groin  The movement of sand along a beach. Longshore Drift A rush of water that flows rapidly back to sea through a narrow opening in a sandbar. Rip Current The total amount of dissolved salts in a water sample. Salinity The daily rise and fall of Earth’s waters on its coastline. Tide A giant wave usually caused by an earthquake beneath the ocean floor. Tsunami The movement of cold water upward from the deep ocean that is caused by wind. Upwelling The movement of energy through a body of water. Wave The vertical distance from the crest of a wave to the trough. Wave Height The horizontal distance between two wave crests. Wavelength  Describe two ways that waves can form Waves can form by the wind and earthquakes beneath the ocean. Explain what happens as a wave approaches the shore Near shore, wave height increases and wavelength decreases. Label the characteristic of a wave.  Wavelength, Crest, trough, wave height, frequency 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. Describe how tide occur. Tides are caused by the interaction of Earth,the moon, and the sun.  Illustrate the difference between spring tides and neap tides.  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. 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 waterDensity- 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. List the gases found in ocean water that are needed by living things Two gases that living things use are carbon dioxide and oxygen.
