Plate Tectonics

3. when two plates go away from each other
5. a single supercontinent
6. where two plates meet
8. two or more of Earth's tectonic plates converge at the subduction point forming a big ditch
10. shaking of the earth when energy is released from friction caused by plate movement
12. places where plates slide sideways past each other.
14. large slabs of rock that divide Earth's crust, move constantly to reshape the Earth's landscape.
15. the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity
16. When something is cut in half in order to determine and gather information

1. a repetition
2. a layer of the earth made of a soft solid
4. how fast something moves, we measure plates cm/year
7. hard solid rock also known as the crust
9. a large plume of hot mantle material rising from deep within the Earth.
11. the process by which the earth's surface slowly rises either due to increasing upward force applied from below or decreasing downward force (weight) from above.
13. when two plates come together
17. occur along divergent plate boundaries, where new ocean floor is created as the Earth's tectonic plates spread apart.
18. when an oceanic plate and continental plate converge and the oceanic plate goes under the continental plate we call it this
