Across
- 1. when one tectonic plate pushes underneath another into the mantle where it melts
- 3. when plates scrape past each other causing strong earthquakes
- 4. when two plates separate causing seafloor spreading, creating underwater volcanic chains and rift valleys
- 5. Movement of magma caused by temperature changes that move the lithospheric plates above
- 6. rocks that form when pebbles, sand, shells, and other pieces are cemented together over time
- 8. where two plates move together to form volcanoes, islands, and other landforms
- 9. Rocks that form when existing rocks change due to heat and/or pressure
Down
- 1. the formation of new areas of oceanic crust at midocean ridges and its movement on either side
- 2. the processes that change the surface of the earth through the movement if the lithospheric plates
- 7. rock that forms when magma cools on the surface or underground
