Across
  1. 4. When two tectonic plates move towards one another. The oceanic crust is forced to sink back into the mantle, whilst the continental crust rises above. Volcanoes and earthquakes are found here.
  2. 7. A sudden shaking of the ground which releases energy and results from underground movement along a fault plane.
  3. 8. A term used to describe a liquid substance (eg rock, glass or metal) formed by heating a solid.
  4. 9. When one crustal plate is forced beneath the other.
  5. 10. When two plates slide past each other in different directions or the same direction at different speeds.
  6. 11. Molten rock that is released from the Earth's core in a volcano or fissure.
Down
  1. 1. Belonging to a continent, eg Africa, Asia, Europe.
  2. 2. Where two plates move apart (diverge), causing a release in pressure that results in a volcanic eruption.
  3. 3. Relating to the ocean.
  4. 5. Occurs when older, denser tectonic plates sink into the mantle, pulling newer and less dense sections of plate along behind.
  5. 6. The region where two or more tectonic plates meet. It is a zone of intense seismic activity.
