Across
- 3. Magma that squeezes between horizontal rock layers
- 7. Large flat land
- 8. Lithosphere that slowly moves over the bottom layer
- 11. Volcano Tall, cone shaped mountain
- 12. A mass of rock formed
- 15. A supercontinent
- 18. Fault Slip past each other sideways, with little up or down motion
- 19. Magma that forces itself across rock layers
- 21. Stress that squeezes a rock until it folds or breaks even
- 22. Boundary Plates converge or come together
- 24. Current Cool fluid
- 25. Stress that pushes a rock in two opposite directions
- 27. A force that acts on rock to change its shape or volume
- 29. Spreading Material add the the ocean floor
- 30. Fault Faults cut through rocks at an angle
Down
- 1. Ancient organism that has been found as a rock
- 2. Hole left when a volcano collapses
- 4. Neck Forms when magma hardens
- 5. Tectonics Plate movement
- 6. Fault Has the same structure as a normal fault
- 9. Oceans rocks sink beneath a deep ocean trench and back into the deep mantle
- 10. Boundary Plates slide past each other
- 13. Ridge Earths longest mountain ranges
- 14. Volcano wide gently sloping mountain
- 16. Middle or region
- 17. drift Wegener's idea that the continents slowly moved
- 20. Transfers heat by the movement of liquid
- 23. Trench Under water canyons
- 25. The stress force that pulls on the crust and thin rock in the middle
- 26. Cone Cone shaped hill or small mountain
- 28. Boundary Plates move apart or diverge
- 30. Breaking in the rocks 's crust then rock's surfaces slip past each other
