Across
- 4. the study of earth and the processes that have shaped its surface throughout time
- 5. a type of igneous rock formed by cooling magma
- 7. rocks formed through the cooling and crystallization of magma in earth’s interior
- 8. plate boundary where two plates move away from each other
- 9. heat rising from the mantle from subduction zones
- 11. slow motions within the earth cause sections of the crust to shift over time
- 13. heat travels upwards, is cooled as it reaches the surface, and sinks back down again
- 14. radiation belts of highly charged particles surrounding the earth in the magnetosphere
- 16. charged particles from earth generate a magnetic field around earth that protects it
- 17. charged particles that flow outwards from the sun
- 18. plate boundary where two plates move towards each other
Down
- 1. oceanic crust sinks below continental crust at convergent plate boundaries
- 2. high temperatures or pressures physically or chemically alter other rocks
- 3. very dense inner layer of the earth that is part liquid and part solid
- 6. separation of earth into layers of different densities
- 10. the thickest layer of the earth that is between the crust and the core
- 12. plate boundary where layers of the crust slide opposite each other
- 15. fragments of other rock or shells that have been cemented together
