Across
  1. 5. this boundary creates rift valleys
  2. 8. this area around the west coast, pacific ocean, and asia house many volcanoes and earthquakes
  3. 9. this process in the mantle is the reason the plates move
  4. 10. this layer of the upper mantle allows the plates to slide over it
Down
  1. 1. the Himalayas are an example of this boundary
  2. 2. This happens when 2 plates of different densities collide
  3. 3. this boundary creates fault lines
  4. 4. tectonic activity creates these
  5. 6. molten rock in the mantle
  6. 7. this is an example of a divergent boundary in the sea
  7. 11. this commonly happens at transform boundaries
