Plate Tectonics
Across
- 3. fault a fault along a plate boundary that moves horizontally
- 6. a stress that pushes rocks together
- 8. where convection currents occurs
- 9. when tectonics plates move toward each other and collide
- 10. when 2 tectonics plates move away from each other
- 12. what it is called when blocks move horizontally
- 14. faults the fault that occurs when a hanging wall moves up
- 15. when 2 plates collide and 1 plate sinks into the mantle, under the other plate
- 17. the result of plate tectonics
- 19. a fracture or zone of fractures between 2 blocks of rock
Down
- 1. the border between 2 plates
- 2. the rigid outer part of the Earth
- 4. tectonics the Earth's surface is cracked into large pieces
- 5. a stress which stretches rock in 2 opposite directions
- 6. currents the movement of tectonics plates, made by heat and pressure
- 7. a stress that occurs when forces are parallel but opposite
- 11. what is formed when cracks in the Earth is made and magma can rise through
- 13. the line formed by the intersection of a horizontal plane and inclined surface
- 16. what plate tectonics are made of
- 18. valley a low region that forms where plates move apart
