Plate Tectonics
Across
- 3. Scale A scale used to measure the magnitude of an earthquake
- 4. The base of the volcano which contains molten rock
- 9. Two plates moving towards each other
- 11. Located at the top of the volcano where the main explosion will take place if it erupts
- 13. Large lumps of lava and rock that can be very destructive
- 14. The action of water rising from the ground to the surface due to the movement of wet land
- 17. A sudden and violent shaking of the ground caused by the movements of the plates
- 18. Regions thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle
- 19. Two plates either moving in the same direction or different direction but at different speed
- 20. The point inside the crust where the pressure is released
Down
- 1. A number to quantify the size of an earthquake
- 2. Hot fluid below or within the earth's crust
- 5. when two plates moving away from each other causing magma to come out between the plate
- 6. A mixture of molten or semi-molten rock within the earth
- 7. Red hot stream of ash and debris that dashes down the side of the volcano
- 8. The outer solid layer of the earth
- 10. When an oceanic plate is forced to go underneath a continental plate
- 12. This is created at collision plate
- 15. The point on the Earth's surface above the focus
- 16. The passage where most of the magma and gases travel up to the surface
