Plate Tectonics
Across
- 3. when underground rock suddenly breaks and there is rapid motion along a fault
- 5. Earth is made out 10-12 big ones and around 20 smaller ones
- 6. occurs when two tectonic plates move away from each other
- 7. when two tectonic plates come together
Down
- 1. an elevated region with a central valley on an ocean floor at the boundary between two diverging tectonic plates where new crust forms from upwelling magma
- 2. causes a fault between two plates of the lithosphere, which will slide past one another
- 3. the planet we live on
- 4. The supercontinent that was torn apart because of the movement in plate tectonics
