Plate Tectonics Part 2
Across
- 4. Is an opening in the earth's crust through which lava, volcanic ash, and gasses escape.
- 5. An underwater volcanic mountain chain where a new ocean floor is formed.
- 6. A theory stating that Earth's crust is broken into huge plates that move and and causes changes at Earth’s surface.
- 11. Molten rock BELOW Earth's surface.
- 12. A plate boundary where two plates pull apart as result of tension stress.
- 14. Rocks formed from compacted sediment.
- 15. Margin that builds up or CREATES.
Down
- 1. Rocks formed from extreme heat and pressure.
- 2. When a dense oceanic plate sinks below a less dense continental plate and melts and creates volcanoes.
- 3. Margin that causes damage or DESTROYS.
- 7. Molten rock ON Earth's surface.
- 8. A plate boundary where two plates come together as a result of compression stress.
- 9. Rocks formed from cooled/solidified molten rock.
- 10. A plate boundary where two plates slide past each other in opposite directions as result of shear stress.
- 13. Cycle Is a series of processes that create and transform the types of rocks in Earth's crust.
