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