Across
- 2. theory stating that Earth's lithosphere is broken into large pieces that move relative to each other
- 3. process by which denser sections of crust are pushed under less dense sections of crust
- 6. large blocks of Earth's broken lithosphere
- 8. a large wave generated by a sudden displacement of water, often resulting from an undersea earthquake
- 9. tectonic plate boundary resulting from two tectonic plates that move away from each other
- 13. process by which new oceanic lithosphere is formed at a divergent boundary
- 14. area of Earth's surface that rises abruptly and reaches an elevation greater than that of a hill
Down
- 1. process by which Earth's magnetic poles switch positions
- 4. an area away from a plate boundary where magma has created a hole through Earth's lithosphere
- 5. the hypothesis that the continents once formed a single large landmass and slowly moved to their current positions
- 7. tectonic plate boundary resulting from two tectonic plates that collide with each other
- 10. tectonic plate boundary resulting from two tectonic plates sliding past each other horizontally
- 11. a crack in Earth's crust typically associated with tectonic plate movement
- 12. mountain surrounding a hole in Earth's crust and formed from the build-up of lava and other eruption materials
