Continental Drift

4. a plate boundary where two plates slide past each other
5. when one tectonic plates is more dense than another and goes under another less dense tectonic plate
7. the theory that the continents move due to convection currents in Earth's mantel
9. a fault that occurs at convergent boundaries
10. a fault that occurs at transform boundaries
12. the layer of the Earth where the tectonic plates are
13. a plate boundary where two plate slide into one another
16. a floating of matter with more energy over matter with less energy that sinks
17. a land formation made by a divergent boundary on continental crust
18. a string of islands formed by subduction at a convergent boundary where oceanic crust meets oceanic crust

1. a land form caused by subduction at a convergent boundary where oceanic crust meets continental crust
2. the layer of the Earth that the tectonic plates float on
3. a land form that is created by pressure above a convergent boundary
5. a growth of the ocean floor where the newest part is in the middle, while the oldest is at the furthest edges due to a divergent boundary
6. a land formation made by a divergent boundary on the sea floor
8. a fault that occurs at divergent boundaries
11. a violent sudden shaking of the Earth's surface due to slippage
14. a super continent where all land was once together billions of years ago
15. a plate boundary where two plates move away from each other
