Across
- 3. Boundary occurs when two tectonic plates move away from each other
- 6. Boundary places where plates slide sideways past each other.
- 7. pull produces a downward force along the rest of the plate.
- 8. an opening in the Earth's crust through which lava, ash, and gases erupt
- 9. the outermost shell of a terrestrial planet.
- 10. the mostly solid bulk of Earth's interior
- 12. Drift large-scale horizontal movements of continents relative to one another and to the ocean
- 14. Suction serves to pull the plate towards the trench.
Down
- 1. Plate massive slab of solid rock made up of Earth's lithosphere
- 2. Boundary When two plates come together
- 4. the sideways and downward movement of the edge of a plate
- 5. a supercontinent that incorporated almost all the landmasses on Earth
- 10. Ocean Ridge a continuous range of underwater volcanoes
- 11. process by which heat is transferred by movement of a heated fluid such as air or water.
- 13. Boundaries boundary between two tectonic plates, where the plates are moving horizontally or vertically
