  1. 6. Evidence for continental drift includes the puzzle-like fit of this continent with South America.
  2. 7. Rocks that form from the accumulation and compression of sediments.
  3. 9. This type of rock forms when magma cools and solidifies.
  4. 10. This type of rock forms under heat and pressure but does not melt.
  5. 12. The continuous process of rock formation, change, and recycling.
  6. 13. The theory explaining the movement of Earth's plates and the resulting geological activity.

  1. 1. This layer of the Earth is broken into tectonic plates.
  2. 2. A type of plate boundary where two plates move away from each other.
  3. 3. When two plates slide past each other, this boundary is formed.
  4. 4. The supercontinent that once existed before breaking into current continents.
  5. 5. The process where rocks are broken down into smaller pieces by wind, water, or ice.
  6. 8. A region where plates move toward each other, often forming mountains or trenches.
  7. 11. This scientist proposed the idea of continental drift.
