Plate Tectonics

2. The process that occurs when one tectonic plate moves under another tectonic plate
4. an underwater mountain chain where new ocean floor is formed. Caused by Divergent Boundary
8. a deep section along the ocean floor beneath which oceanic crust slowly sinks toward the mantle
9. A supercontinent containing all of Earth's land that existed about 225 million years ago.
10. the theory that the continents were once joined and then slowly drifted apart
12. the layer of the earth between the crust and the core, has magma
13. Energy or vibrations that are released due to plate movement
14. A deep valley that forms where two plates move apart

1. The preserved remains of an organism that lived in the past
3. Circular currents in the mantle caused by the magma being heated by the core off the Earth.
5. A plate boundary where two plates move toward each other, example is The Rocky Mountains
6. A plate boundary where two plates move away from each other, example is Mid-Atlantic Ridge or Great Rift Valley
7. a rigid layer of the Earth's crust that is believed to drift slowly
10. Earth's outermost layer.
11. A plate boundary where two plates move past each other in opposite directions example New Madrid Fault
15. A geological feature that indicates a break in a rock due to stress
