Across
- 1. The portion of motion of a tectonic plate that can be accounted for by its subduction.
- 4. Sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.
- 6. A type of fault whose relative motion is predominantly horizontal, in either a sinistral or dextral direction.
- 9. An actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide.
- 10. The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise.
- 13. A change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged.
- 14. A theory explaining the structure of the earth's crust from the interaction of rigid lithospheric plates.
- 16. Theory that explained how continents shift position on Earth's surface.
Down
- 2. The rigid outer part of the earth, consisting of the crust and upper mantle.
- 3. A linear feature that exists between two tectonic plates that are moving away from each other.
- 5. Formation of new areas of oceanic crust, occurs at mid-ocean ridges.
- 7. When the hot and neutral connections at a receptacle are wired “backwards.”
- 8. The movement, formation, or re-formation of continents described by the theory of plate tectonics.
- 11. A hypothetical super-continent that included all the landmasses of the earth before the Triassic Period.
- 12. Where the magnetic north points (roughly) towards the geographic north pole.
- 15. Sliding plate force is a proposed mechanism for plate motion in plate tectonics.
