Across
- 1. boundary where plates collide and create mountains
- 4. Outer most physical layer
- 7. boundary where plate movement causes midoceanridge
- 8. type of rock that is created due to heat and pressure
- 9. when one plate goes under another less dense plate
Down
- 1. currents occur in asthenosphere when heat rises and cool particles sink
- 2. densest compositional layer equals 1/3 earth's mass
- 3. heat transfer from one solid to another
- 5. electromagnetic waves from the Sun
- 6. occur when 2 plates slide past each other
