Plate Tectonics Quiz

5. Type of crust that is lighter and less dense.
7. The molding together of wet sediments and/or rock.
11. Rock that is formed from extreme heat and pressure underground.
13. Rock that is formed due to cooled magma.
14. This type of boundary results in the formation of volcanoes and mountains due to collision.
15. Type of crust that is heavier and more dense.
16. The remains of long deceased organisms. Wegner used their shared presence across multiple continents as evidence for Continental Drift.
19. The moving of rock
20. This layer of Earth is pulled upon by convection currents to move crust.
22. The division of Earth's crust in sections known as plates.

1. The pressing together of sediment and/or rock.
2. New rock is located on the surface and Old rock is further beneath the surface.
3. The break down of rock
4. Folding of heavier and more dense crust underneath less dense crust.
6. The movement of magma; hot magma rises, pulls on the crust and moving it. The cooler magma sinks back down to the core.
8. When plates separate, new crust is made. This generally occurs on the ocean floor.
9. The rock is settled into a new location.
10. This layer of Earth includes all of Earth's solidified rock.
12. This type of boundary results in strong earthquakes when the plates slide.
17. This type of boundary results in continental drift and new oceanic crust due to division.
18. The idea that Earth's continents are moving away from each other.
21. Rock that is formed through layering of previously weathered sediments.
