- 7. as plates collide,one sinks
- 8. dense with rock like basalt
- 9. causes the movement of plates
- 11. form near trenches
Down
- 1. process of the lithosphere divided into plates
- 2. fluffy with rock like granite
- 3. quartz, feldspar, mica, amphibole, olivine, and calcite.
- 5. a layer of silicate rock in between the crust and core
