Across
- 4. portion of motion of a tectonic plate that can be accounted for by its seduction.
- 5. drift the gradual movement of the continents across the earth's surface through geological time.
- 6. linear feature that exists between two tectonic plates that are moving away from each other.
- 8. Earth's outer shell is divided into several plates that glide over the mantle
- 9. a line on a diagram or map connecting points relating to the same time or equal times.
- 11. a change in the earths magnetic field
- 12. the branch of geophysics concerned with the magnetism in rocks that was induced by the earth's magnetic field at the time of their formation.
- 13. super continent that existed during the late Paleozoic and early Mesozoic eras.
Down
- 1. instrument used for measuring magnetic forces, especially the earth's magnetism.
- 2. the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.
- 3. a large elongated depression with steep walls formed by the downward displacement of a block of the earth's surface between nearly parallel faults or fault systems.
- 5. s an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide.
- 7. the formation of new areas of oceanic crust
- 8. type of fault whose relative motion is predominantly horizontal in either sinistral or dextral direction.
- 10. sliding plate force is a proposed mechanism for plate motion in plate tectonics
