Plate Tectonics
Across
- 3. A volcanic mountain that forms along a convergent boundary.
- 7. A region where two tectonic plates are moving towards each other and one is forced beneath the other.
- 9. The boundary between the Earth's crust and mantle.
- 10. The process by which new oceanic crust is formed at a divergent boundary.
- 11. The process by which one tectonic plate moves past another.
- 15. The theory that explains how the Earth's lithosphere is broken into several plates that move relative to each other.
- 17. A type of seismic wave that moves through the Earth's interior and can only be detected with special instruments.
Down
- 1. A chain of volcanic islands that form along an oceanic-oceanic convergent boundary.
- 2. The layer of the Earth that is located beneath the crust and is composed of dense, solid rock.
- 4. A boundary where two tectonic plates are moving towards each other.
- 5. The supercontinent that existed approximately 300 million years ago.
- 6. A boundary where two tectonic plates are moving away from each other.
- 8. A type of seismic wave that moves through the Earth's interior and can be detected on the Earth's surface.
- 9. A type of boundary where two plates are moving apart and magma rises to fill the gap between them.
- 12. The point on the Earth's surface directly above the focus of an earthquake.
- 13. A section of the Earth's lithosphere that moves as a single unit.
- 14. The study of the Earth's crust and the processes that shape it.
- 16. The type of boundary where two plates slide past each other.
- 17. The process by which one tectonic plate moves beneath another and sinks into the mantle
