Across
- 5. the outermost layer of the earth

- 8. this is the second layer of the Earth that makes 60% of the planet's mass.
- 11. it is composed of the upper mantle and crust
- 12. giant pieces of the earth's crust
- 13. elements found in the inner and outer core
- 14. this is formed when subduction happens
- 16. it is the study of the earth
- 18. this is the process where the plates move below another plate
- 19. plate boundaries that slide past each other
- 20. these are plate boundaries that moves away from each other
- 21. plates that are found on land
- 22. the solid core
- 23. it is the movement of the upper mantle
Down
- 1. the supercontinent
- 2. These is the plates that are found under the sea
- 3. the part of the upper mantle where magma flows
- 4. this is the device that measures the waves of the ground
- 6. the liquid core
- 9. plate boundary that moves towards each other
- 10. states that a long time ago there is one supercontinent on earth
- 12. the ocean around the supercontinent
- 15. these are formed above convergent boundaries
