Plate Tectonics
Across
- 4. The Kobe earthquake measured 6.9 on this scale.
- 7. What fault causes earthquakes in California? (3,7)
- 8. Type of plate boundary where crust is neither created nor destroyed.
- 9. Zone where oceanic crust is forced down and under continental crust.
- 11. In December 2004 one of these hit Indonesia. It resulted in over 120,000 deaths.
Down
- 1. A sudden tremor or movement of the earth's crust, which originates naturally at or below the surface.
- 2. As two continental plates move towards each other, they are forced upwards creating this feature. (4,9)
- 3. The force which opposes the motion of one plate surface as it moves across another plate.
- 5. A deep sea feature created by subduction.
- 6. Type of plate margin characterised by subduction zones and long fold mountain chains.
- 7. An instrument used to measures force and duration of an earthquake.
- 10. There is one in the Mid-Atlantic, and Iceland sits on one.
