plate tectonics
Across
- 1. molten rock below the earth's surface
- 3. the separating of continents by drifting across the oceans
- 6. a layer of 'plastic' semi-solid rock in the lower mantle
Down
- 1. patterns of magnetism trapped in rocks on each side of the plate boundaries
- 2. a place where extremely hot material from inside the earth erupts at the surface
- 4. molten rock that has erupted onto the earth's surface
- 5. a huge wave in the ocean caused by an earthquake occurring on the seafloor
