- 9. the layer of Earth that is made up of tectonic plates
- 11. a very deep underwater valley
- 12. the process in the mantle that makes plates move
- 14. the type of plate movement that created the Himalayan Mountains
- 15. these seismic activities occur at all types of plate boundaries
Down
- 1. the type of plate movement that creates trenches and volcanoes
- 5. a long crack in the crust that lets magma seep up to the Earth's surface
- 6. the layer directly below the crust
- 7. the thick type of crust that has continents attached
