  1. 1. one plate slides horizontally past another.
  2. 5. is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide.
  3. 9. is the portion of motion of a tectonic plate that can be accounted for by its subduction.
  4. 10. is a linear feature that exists between two tectonic plates that are moving away from each other.
  5. 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.
  6. 13. sliding plate force is a proposed mechanism for plate motion in plate tectonics.

  1. 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. 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. 3. Changes in direction or orientation of the magnetic field of the Earth that have occurred from time to time.
  4. 4. a line on a diagram or map connecting points relating to the same time or equal times.
  5. 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.
  6. 7. is the movement of the Earth's continents relative to each other
  7. 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.
  8. 12. an instrument used for measuring magnetic forces, especially the earth's magnetism
