Tectonic Plates

4. When oceanic crust melts it can result in the formation of a __________.
6. floor spreading, The process by which new oceanic lithosphere is created.
9. zone, A __________ __________ is a convergent boundary where an oceanic plate is pushed beneath a continental plate forming a trench. The oceanic crust melts resulting in the formation of volcanoes.
10. Currents, A circulation pattern in which material is heated and rises in one area then cools and sinks in another area, flowing in a continuous loop
11. Tectonic Theory, theory that Earth's lithosphere is divided into.
14. Ridge, The __________-__________ __________ is an example of a divergent boundary.
15. a place where two tectonic plates meet.
16. At a __________ plate boundary, new crust is created as two or more plates pull away from each other.
17. plates, like pieces of a puzzle
18. Earthquakes often occur at __________ lines.

1. When oceanic plates collide with continental plates a __________ will form between the two plates.
2. When a divergent boundary occurs on land a __________, or separation, will arise and over time, that mass of land will break between them.
3. When two continental plates collide large __________ will usually form.
5. boundaries, The boundary where two tectonic plates meet and push into one another.
7. Transform boundaries (faults) cause __________.
8. The __________ mountain range was formed from the collision of the Indian plate colliding into the Eurasian plate.
9. A region where oceanic plates sink down.
12. boundary, The plate boundary where two tectonic plates move away from one another.
13. ridges, Underwater mountain ranges where the crust is spreading apart creating new ocean floor.
