Plate Tectonics
Across
- 2. long crack in the surface on the earth, earthquakes usually occur
- 3. tectonic plates that lie under surface land masses
- 7. sea floor mountain system formed by divergent boundaries
- 8. when two plates move away from each other Ex: rift valley, mid ocean ridge
- 9. when two tectonic plates move towards each other and collide Ex:uplift, mountains
Down
- 1. parallel pattern of rock material found at identical locations across the Mid-Atlantic Ridge
- 4. when two plates slide past each other Ex: fault lines
- 5. when a denser plate is pushed down and beneath a less dense plate, creates volcanoes
- 6. tectonic plates that are at the bottom of the ocean
