2. the 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.
4. process that occurs at mid-ocean ridges
5. sliding plate force is a proposed mechanism for plate motion in plate tectonics.
8. the theory that Earth's outer shell is divided into several plates that glide over the mantle.
9. a type of fault whose relative motion is predominantly horizontal in either sinistral or dextral direction.
11. a linear feature that exists between two tectonic plates that are moving away from each other.
12. a supercontinent that existed during the late Paleozoic and early Mesozoic eras.
13. an imaginary line or a line on a chart connecting points
14. an instrument used to detect the presence of a metallic object or to measure the intensity of a magnetic field.

1. a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged.
2. the portion of motion of a tectonic plate that can be accounted for by its subduction.
3. an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide.
6. a linear-shaped lowland between several highlands or mountain ranges created by the action of a geologic rift or fault
7. the movement of the Earth's continents
10. the study of the record of the Earth's magnetic field in rocks, sediment, or archeological materials
