Plate Tectonics

2. This is a fancy word for "sinking" or the downgoing motion of a plate
4. This is a feature that is created in ocean/ocean convergence
6. This is a feature that is created in continent/continent convergence
7. This is the process in which the seafloor spreads allowing crust to move farther from the ridge over geologic time.
9. This boundary involves crust that divides
11. This is common at all types of plate boundaries
12. This type of crust is thicker than oceanic
13. The plates in which the lithosphere is divided (puzzle pieces)
14. How much the continents move each year
16. This is a narrow ditch at the bottom of the ocean, located above a subduction zone
18. This boundary involves crust that slides
19. This zone allows for one plate (denser plate) to sink or subduct below another one
20. The San Andreas Fault is located in this state
21. This is a zone of seismic and tectonic activity along the edges of lithospheric plates

1. This is a feature created in continent/oceanic convergence
3. This boundary involves crust that collides
5. This type of crust is denser than continental
8. The Mid-Atlantic Ridge is located in this ocean
10. The name of the supercontinent that existed 300 million years ago
15. This forms at a divergent boundary where the plates spread
17. This mountain range is a result of the collision of India with Southern Asia
