1-4. Label the four layers of the Earth.

Click and hold the numbered boxes below and highlight the correct answer.

  1. Questions 5-7, click on the button in front of the correct answer.

    5. Explain how the mantle's convection currents move the Earth's plates?

    The deepest zone of the mantle is much hotter that the upper zone. Hot material rises to the top of the mantle and then cools and sinks. This rising and sinking happens in a circular motion. When the mantle flows it moves the plates.

    Vibrations from the tightly packed metals of the inner core cause the liquid material of the mantle to move in circles.

    Giant fish swim circles in the mantle, and when they get to the top, their fins catch on the continents and move them along the surface of the Earth.

    6. What is happening at a transverse plate boundary?

    A transverse plate boundary has two plates moving apart, creating a ridge where hot magma rises to the surface.

    A transverse plate boundary has one plate moving up over another plate.

    A transverse plate boundary has two plates sliding by each other. Both plates are moving in opposite directions. A transverse boundary is like a tear in the Earth's crust.

    7. Name two pieces of evidence that scientists have used to base the Continental Drift Theory on.

    Scientists have used 1)Impact craters between continents which have been split apart by drifting and 2)Difference between high and low tides due to the pull of the continents as they drift apart.

    Scientists have used 1)The difference in time of sunrise and sunset because of the drifting of continents and 2)The fact that areas of different continents that were once together still have the same weather patterns.

    Scientists have used 1)magnetic bands in rocks and 2)fossils of tropical plants and animals that have been found in places like Antarctica and Greenland. They have also used fossils of fish found in high mountain regions in the center of continents.

    8. The collision of the Indian plate and the Eurasian plate produced the Mountains, the highest mountain range in the world.


    9. What type of mountain formation is shown in the diagram below?




    10. What type of mountain formation is shown in the diagram below?




    Questions 11-13, Click on the button in front of the right answer.

    What is happening at the following plate boundaries?

    11. Collision boundary-

    Two plates are moving in opposite directions causing magma to fill the void and producing "NEW" crust. This is also spreading the oceans making them wider.

    Two plates are crashing into each other causing mountain building, volcanic activity, and earthquakes.

    Two plates are sliding past each other moving in opposite directions.

    12. Separation boundary-

    Two plates are moving in opposite directions causing magma to fill the void and producing "NEW" crust. This is also spreading the oceans making them wider.

    Two plates are crashing into each other causing mountain building, volcanic activity, and earthquakes.

    Two plates are sliding past each other moving in opposite directions.

    13. Transverse boundary-

    Two plates are moving in opposite directions causing magma to fill the void and producing "NEW" crust. This is also spreading the oceans making them wider.

    Two plates are crashing into each other causing mountain building, volcanic activity, and earthquakes.

    Two plates are sliding past each other moving in opposite directions.

    Questions 14-23, Select the right answer from the ones in the boxes. Please only use each answer in the sections only once.

    Matching Vocabulary I
    14. subduction zone A Pieces of the crust that "float" on the mantle.
    15. convection currents B The only ocean on Earth 250 million years ago.
    16. Pangea C Movements in a material caused by hotter material rising and cooler material sinking.
    17. Plates D Supercontinent 250 million years ago
    18. Panthalassa E Area where two plates are colliding. One plate is pushed down under the other plate.


    Matching Vocabulary II
    19.Magma A The northern half of Pangea after it split apart.
    20.Continental Drift Theory B The deepest places on the surface of the Earth. They are located at subduction zones.
    21.Mid-ocean ridge C Molten rock below the surface of the Earth
    22.Laurasia D Place where two plates are separating. These plates are moving in opposite directions making the oceans larger.
    23.Trenches E The idea that the Earth's plates are "floating" on the mantle and have been for millions of years.
