Plate Tectonics

2. the type of evidence supporting continental drift which involves the continents sticking together like a puzzle
4. type of spreading away from each other
11. a hypothesis which suggests all continents were connected and drifted apart
15. a hypothesis that suggest new oceanic crust is produced at the crests of mid-ocean trenches
17. type of crust that is less dense
18. elevated areas of the seafloor characterized by volcanism
20. a mountain range created by continental-continental convergence

1. type of spreading towards each other
3. the largest plate
5. temperature ‘’ as density decreases
6. a structure formed by continental-continental convergence
7. a structure formed by both continental-oceanic convergence and oceanic-oceanic convergence
8. the layer of earth that is below the crust and where convection occurs
9. the process which moves plate tectonics
10. type of crust that is more dense
12. type of plate that we live on
13. type of spreading that moves side-to-side
14. the type of evidence supporting continental drift which involves animal remains
16. temperature ‘’ as density increases
19. the name of the supercontinent present 200 million years ago
