Plate Tectonics

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

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
