Plate Tectonics
Across
- 1. Cooled and solid rock from the Earth's upper mantle and the crust
- 3. A type of boundary where plates slide past one another
- 4. One theory of how plates move;Plates sink as they get older
- 6. Where continental crust collides with oceanic crust, causing the oceanic crust to slide under the continental crust
- 9. A type of boundary where plates come together and collide
Down
- 1. The big mass of land on earth before the plates moved away from each other
- 2. The man who discovered the theory of plate tectonics
- 5. The zone above a subduction zone where there is a deep, narrow depression in the oceanic crust
- 7. A type of boundary where plates spread apart from each other
- 8. One theory of how plates move;Hot molten rock moves the plates
