    throughout time?
  • It includes the continents, but not the ocean
  • It is a changing, moving surface with the same
    thickness everywhere.

  • 8. The average density of one of the continental
    crusts is 2.8 g/cm3 and the average density of
    one of the oceanic crusts is 3.2 g/cm3. If
    these two plates came together, what could be
    expected to happen?
  • The two plates would push apart and form a rift
  • The oceanic plate would rise up over the
    continental plate.
  • The oceanic plate would be pushed under the
    continental plate.
  • The two plates would meet head on and rise up to
    form mountains

  • 9. If we compare the temperature and pressure of
    the Earths mantle to the core, what differences
    can we expect as we move downward into Earth?
  • Both the temperature and pressure increase
  • Both the temperature and pressure decrease

  • S6E3d. Explain the causes of waves, tides and

  • On most ocean shorelines, the water rises slowly
    and covers land twice a day. Then it slowly
    falls back. What is this movement called?

  • Drift

    every day?
  • Because deep ocean currents are constantly

    are constantly changing
  • Because the direction of the wind over the ocean
    is constantly changing

  • 4.Why does the ocean cover different amounts of
    the beach at different times of the day?
  • Because the moons gravity pulls the ocean,
    causing it to rise and fall
  • Because earth wobbles as it rotates, causing the
    ocean to rise and fall
  • Because the ocean currents change, adding sand to
    and removing sand from the beach
  • Because sand is able to absorb more water as the
    temperature increases, lowering the ocean level

    other relative to the moon.
  • The sun and moon were at right angles to each
    other relative to earth.

    between the sun and the moon.

  • 8. Karla is gong to search for clams and oysters
    during low tide. If she knows that high tide is

    start searching for shellfish?
  • 1000pm
  • 400 pm
  • 1000 am the next day
  • 200 pm

  • 9. Deep currents form when
  • Cold air decreases water density
  • Warm air increases water density
  • The ocean surface freezes and solids from the
    water underneath are removed
  • Salinity increases

  • 10. When waves approach the shore,
  • They speed up
  • They maintain their speed
  • Their wavelength increases
  • Their wave height increases

  • 3. If a rock and container of water have the same
    mass and temperature and are exposed to the same
    amount of heat energy, what will MOST likely
  • The water will transfer the heat to the rock
  • The rock will transfer heat to the water
  • The temperature of the rock will rise faster
  • The temperature of the water will rise faster.

  • 4. While visiting the beach during a summer
    vacation, a sea breeze keeps you cool and
    comfortable during the hottest part of the day.
    Which BEST explains why this happens?
  • Warm air rising over land allows cooler air from
    the ocean to blow inland
  • Cool air rising over land allows warm air form
    the ocean to blow inland
  • There are similarities in temperature between the
    land and water
  • A storm is approaching

  • 5. Which statement about Earths heating patterns
    is true?
  • The rate of cooling depends on the season
  • Large bodies of water cool more quickly than land
  • Land cools more quickly than large bodies of
