Across
- 5. the central point on the Earth's surface directly above the point within the Earth where the earthquake actually occurred
- 7. the scientific study of the universe
- 11. the solid, rocky layer covering the entire surface of the planet, composed of the crust and the hard uppermost mantle
- 13. the scientific study of the earth and its origin
- 16. the boundary between the Earth's crust and the mantle
- 17. a small earthquake that follows a main earthquake
- 19. movement- process by which soil, regolith, and rock move downslope under the force of gravity
- 21. major cross-formation break with accompanying Displacement of one side against the other
- 24. origin of an earthquake underground
- 25. the concept that the earths crust is floating in Gravitational balance upon the material of the mantle
Down
- 1. the layer of Earth between the core and crust
- 2. cone- a small volcano built primarily of pyroclastic material ejected from one single vent (also most often seen)
- 3. a break in the Earth's crust caused by movement of rock
- 4. the accumulation of small to large sediment particles and undergoes compaction, cementation
- 6. cone- a kind of volcano usually formed when an explosive eruptions of sticky lava alternate with Quieter eruption of volcanic rock bits
- 8. the water portion of the earth
- 9. boundaries- 2 plate tectonic plates that move away from each other
- 10. magma that reaches earths surface
- 12. rocks formed by the crystallization of magma
- 14. all life on earth
- 15. an area where material from within the mantle Rises and melts forming magma
- 18. A minor tremor of the earth that precedes a larger earthquake originating at approximately the same location
- 20. a mineral and its resistance to scratching
- 22. molten rock in earths mantle
- 23. the thin rocky outer layer of the earth
