Plate tectonics
Across
- 3. molten rock under the surface
- 5. the top layer of rocks on the Earth, the crust and the uppermost mantle
- 8. a boundary between tectonic plates or a weak spot on a plate, where earthquakes occur and the relative position of the ground changes
- 12. All of the living things on Earth
- 14. rock formed from layers of dirt, silt or sand
- 16. rock rock that has been changed without completely melting by high temperature and pressure
- 17. type of fault where the plates move towards each other
- 20. type of rock formed from cooled molten rock
- 21. exact point where an earthquake originated (under the ground)
- 22. the middle layer of molten hot rock of the Earth
Down
- 1. type of fault where the ground separates
- 2. the solid layer on the outside of the Earth
- 4. All the rocks and minerals, molten and solid, making up the Earth
- 6. All of the gases surrounding the Earth
- 7. type of fault where two plates moves along each other in opposite directions
- 9. tectonics study of the movement of the Earth’s crust as a series of large slabs moving in different directions
- 10. molten rock that has erupted onto the surface
- 11. one plate moves under another
- 13. point on the ground where an earthquake originated
- 15. the movement of magma into other layers of rock
- 18. centre of the Earth, extremely hot and dense with high iron content
- 19. the bending of rock into anticlines and synclines as the rock gets compressed
