Across
- 4. a break in Earth’s crust where the rocks on either side have moved
- 5. depressions of the sea floor, relatively narrow in width, but very long. the deepest parts of the ocean floor
- 7. the scientific theory that the crust is made up of rigid pieces, called tectonic plates, that move across Earth’s surface
- 10. the process by which a collision between two tectonic plates forces the denser plate under the less dense plate
- 13. A seafloor mountain system formed by plate tectonics, found at divergent boundaries
Down
- 1. a plate boundary where two of more plate are moving apart
- 2. the hypothesis that the continents slowly drifted to their current positions after having been part of a single, giant landmass that broke apart
- 3. The edge of two or more tectonic plate
- 6. a plate boundary where two of more plate are moving past each other
- 8. a plate boundary where two of more plate are moving together
- 9. At a mid-ocean ridge the plate boundary slowly pull away from each other, allowing molten rock to rise, solidify, and form new seafloor
- 11. break in the crust of Earth object,that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface
- 12. a natural disaster that occurs on a fault when plates shift
