- 5. Melted rock that reaches Earth's surface.
- 7. A rock formed from layers of sediments that are compacted and cemented together.
- 9. The thin, outer layer of the Earth.
- 10. The movement of heat within the mantle that helps move tectonic plates.

Down
- 1. The process where one tectonic plate moves beneath another into the mantle.
- 3. A rock changed by heat and pressure without melting.
- 4. The process where sediments are dropped and settle in a new location.
- 6. The movement of rock, soil, or sediment by water, wind, ice, or gravity.
- 8. The process where minerals glue sediments together to form rock.
- 11. An opening in Earth's crust where magma, ash, and gases escape.
- 12. Small pieces of rock, minerals, or organic material.
