2. proposed mechanism for plate motion in plate tectonics.
4. Places where plates slide past each other
7. 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
8. a linear feature that exists between two tectonic plates that are moving away from each other.
11. Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core
14. measure the magnetization of a magnetic material like a ferromagnet, or to measure the strength and, in some cases, the direction of the magnetic field at a point in space.
15. the study of magnetic record on rocks

1. process that occurs at mid-ocean ridges
3. an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide.
5. 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
6. the portion of motion of a tectonic plate that can be accounted for by its seduction
9. a line on a diagram or map connecting points relating to the same time or equal times
10. a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged
12. a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It formed approximately 300 million years ago and then began to break apart after about 100 million years
13. the movement of the Earths continents relative to each other, thus appearing to drift
