Across
- 1. is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged.
- 5. measurement instruments used for two general purposes: to 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.
- 6. a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity
- 9. , is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide
- 10. is the study of the record of the Earth's magnetic field in rocks, sediment, or archeological materials.
- 13. Ridge push or sliding plate force is a proposed mechanism for plate motion in plate tectonics.
- 15. is the movement of the Earth's continents relative to each other
Down
- 2. is a type of fault whose relative motion is predominantly horizontal
- 3. portion of motion of a tectonic plate that can be accounted for by its subduction.
- 4. is a linear feature that exists between two tectonic plates that are moving away from each other.
- 7. Earth's outer shell is divided into several plates that glide over the mantle,
- 8. a linear-shaped lowland between several highlands or mountain ranges created by the action of a geologic rift or fault.
- 11. a line on a diagram or map connecting points relating to the same time or equal times.
- 12. he 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.
- 14. a supercontinent
