Across
- 3. Long deep ditch on the seafloor
- 6. process where sediments and other materials are added together to "build"
- 7. Plate boundary where two lithospheric plates collide and destroy.
- 10. Rupture in the crust that has magma inside and erupts hot lava.
- 11. Naturally occurring, inorganic solid substance having a specific chemical composition and characteristic crystalline structure, color, and hardness.
- 15. cooled lava under the earth's surface.
- 17. when the earth shakes
- 18. process when bits of rock get broken down into small pieces.
- 19. Crust and upper part of the mantle
- 20. a type of rock made by cooled magma, which is molten rock melted from pressure and heat under earths crust.
- 21. Plate bound
- 22. Plate tectonics that go in opposite directions
Down
- 1. type of volcano with deep cracks, when under tension they pull apart and lava comes out.
- 2. the process when sediments turn into rocks
- 4. a type of rock formed by small sediments cementing together.
- 5. Upper layer of earth's mantle, below the lithosphere, very weak
- 8. movement of sediments from one place to another
- 9. Cracks in the earths crust
- 12. the substance that comes out of volcanoes, the stage before magma cools is called...
- 13. Outermost layer of the earth
- 14. volcano and earthquake activity
- 16. a type of rock formed by any type of existing rock, in which minerals are changed in structure of composition by pressure and heat.
