tectonic plate

1. a fault-bounded area or region with a distinctive stratigraphy, structure, and geological history.
3. the upper layer of the earth's mantle, below the lithosphere.
4. arcs/ a curved chain of volcanic islands located at a tectonic plate margin.
6. when one tectonic plate moves under another.
9. sudden movement along faults within the Earth.
11. the relatively thin part of the earth's crust which underlies the ocean basins.
13. Earth's tectonic plates converge
14. a supercontinent that existed during the late Paleozoic and early Mesozoic eras
15. The heat from radioactive processes within the planet's interior

1. fault boundaries/ plates slide past one another without the production or destruction of crust.
2. one of the large pieces of the surface of the earth that move separately.
5. This occurs when plates move towards each other and collide.
7. he rigid outer part of the earth, consisting of the crust and upper mantle.
8. occurs when two tectonic plates move away from each other.
10. break apart or become separated through faulting caused by plate tectonics.
12. mountain ranges/ mid-ocean ridge.
