Tectonic plates

2. Areas where the plates meet
4. a set of stress directed toward the center of a rock mass
6. an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma
8. the outer layer of the Earth.
9. occurs when oceanic crust meets continental crust and when oceanic crust meets oceanic crust
10. An ocean plate collides with another ocean plate which forms a trench.
12. When plates move away from each other
13. When heat from the Earth's core creates currents in the crust, the tectonic plates can scrape, bump, or drag along each other.
14. cracks in the earth's crust along which there is movement.
17. heat-driven cycles that occur in the air, ocean, and mantle.
18. long, narrow depressions on the seafloor that form at the boundary of tectonic plates where one plate is pushed, or subducts, beneath another.
19. a solid layer made of the crust and the solid upper mantle
20. the rigid outer part of the earth, consisting of the crust and upper mantle.

1. destroy the Earth's crust
3. An oceanic plate collides with a less dense continental plate which forms a deep ocean
5. A continental plate collides with another continental plate which forms mountains.
7. a layer of the interior of the Earth.
10. the outer layer of the core that is made of liquid iron and nickel.
11. an opening in the Earth's surface
15. the deepest and hottest layer of our planet.
16. a semi-fluid layer located in the upper part of the Earth's mantle, situated beneath the lithosphere
