Across
- 2. Measurement instruments used for two general purposes: to measure the magnetization of a magnetic material.
- 5. Two plates moving towards each other
- 6. linear-shaped lowland between several highlands or mountain ranges created by the action of a geologic rift or fault.
- 7. supercontinent
- 9. Two plates slide horizontally past each other.
- 12. a line on a diagram or map connecting points relating to the same time or equal times
- 14. new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
- 15. Portion of motion of a tectonic plate that can be accounted for by its subduction.
Down
- 1. Two plates moving away from each other.
- 3. Says the Earth's crust is made up of about a dozen major plates that rest on hot mantle.
- 4. The study of the remnant magnetization in rocks.
- 8. movement of the Earth's continents relative to each other.
- 10. Process that takes place at convergent boundaries by which one tectonic plate moves under another tectonic plate and sinks into the mantle as the plates converge.
- 11. Change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged.
- 13. sliding plate force is a proposed mechanism for plate motion in plate tectonics.
