Across
- 3. Boundary where plates collide leading to subduction or mountain building
- 5. The thin dense outer layer of Earth found beneath the ocean basins
- 7. Boundary where plates slide past each other along fault lines causing earthquakes
- 10. Massive slabs of lithosphere that move and interact to shape Earth's surface
- 11. A region where oceanic crust sinks down into the mantle beneath another plate
- 12. The point on Earth's surface directly above where an earthquake originates
- 14. Boundary where plates rift and spread apart creating mid ocean ridges
- 15. Evidence from earthquakes used to predict and map plate margins and fault lines
Down
- 1. The driving force behind plate motion where heat rises and falls within the earth
- 2. A major area in the basin of the Pacific Ocean where many earthquakes and volcanoes occur
- 4. A fracture or zone of fractures between two blocks of rock that slide past each other
- 6. A deep valley that forms where continental crust diverges and pulls apart
- 8. The thick less dense outer layer of Earth that forms the large landmasses
- 9. An underwater mountain system formed by plate rifting and spreading
- 13. Geological anomalies or hotspot volcanoes like Hawaii that are not driven by boundaries
