Across
- 3. The branch of geophysics concerned with the magnetism in rocks.
- 6. An instrument used for measuring magnetic forces, especially the earth's magnetism.
- 7. The portion of motion of a tectonic plate that can be accounted for by its subduction.
- 8. Changes in direction or orientation of the magnetic field of the Earth that have occurred from time to time.
- 9. A theory in geology the lithosphere of the earth is divided into a small number of plates which float on and travel independently over the mantle and much of the earth's seismic activity occurs at the boundaries of these plates.
- 14. A proposed mechanism for plate motion in plate tectonics.
- 15. The sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.
Down
- 1. A line connecting points to the same time or equal times.
- 2. The movement of the Earth's continents relative to each other.
- 4. A type of fault whose relative motion is predominantly horizontal in either sinistral or dextral direction.
- 5. A linear feature that exists between two tectonic plates that are moving away from each other.
- 10. A large elongated depression with steep walls.
- 11. Supercontinent that existed during the late Paleozoic and early Mesozoic eras.
- 12. An actively deforming region where two tectonic plates move toward one another and collide.
- 13. A process that occurs at mid-ocean ridges.
