Plate Tectonics

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

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
