Across
- 1. one plate slides horizontally past another.
- 5. is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide.
- 9. is the portion of motion of a tectonic plate that can be accounted for by its subduction.
- 10. is a linear feature that exists between two tectonic plates that are moving away from each other.
- 11. 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. sliding plate force is a proposed mechanism for plate motion in plate tectonics.
Down
- 1. the lithosphere of the earth is divided into a small number of plates which float on and travel independently over the mantle and much of the earth's seismic activity occurs at the boundaries of these plates.
- 2. is 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.
- 3. Changes in direction or orientation of the magnetic field of the Earth that have occurred from time to time.
- 4. a line on a diagram or map connecting points relating to the same time or equal times.
- 6. 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.
- 7. is the movement of the Earth's continents relative to each other
- 8. was 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.
- 12. an instrument used for measuring magnetic forces, especially the earth's magnetism
