Across
- 2. The point on the Earth's surface directly above the focus of an earthquake
- 6. The rigid outer part of the earth, consisting of the crust and upper mantle.
- 7. A plate boundary where two plates move toward each other.
- 9. Loose particles created by weathering and erosion of rock
- 11. A rock formed by the crystallization of molten magma
- 13. A naturally occurring solid mixture of one or more minerals or organic matter
- 14. Rock formed from the weathered products of preexisting rocks that have been transported, deposited, compacted and cemented.
- 17. The process in which rock is broken down by chemical reactions; changes the rock's molecular composition
- 19. A naturally occurring, inorganic solid that has a crystal structure and a definite chemical composition
- 20. Vibrations that travel through Earth carrying the energy released during an earthquake
- 22. A plate boundary where two plates move past each other in opposite directions
- 23. A fracture in Earth along which movement has occurred
- 24. A natural resource that can be replaced at the same or below rate at which the resource is consumed
- 25. A natural resource that is consumed faster or above the rate in which it is replaced.
Down
- 1. A plate boundary where two plates move away from each other.
- 3. Rock formed by the alteration of preexisting, solid rock deep within the Earth by heat, pressure, and/or chemically active fluids
- 4. A concentration of heat in the mantle capable of producing magma, which rises to Earth's surface
- 5. The process by which plate tectonics produces new oceanic lithosphere at ocean ridges
- 8. A liquid's resistance to flowing -or- the thickness of a liquid
- 10. The process in which rock is physically broken into smaller pieces; no change in rock composition.
- 12. The transportation of material by a mobile agent, such as wind, water, or ice
- 15. A device that records ground movements caused by seismic waves as they move through Earth
- 16. Magma that reaches Earth's surface
- 18. The soft upper layer of the mantle just below the lithosphere. Lithospheric plates float on top of it.
- 21. A body of molten rock found at depth, including any dissolved gases and crystals.
- 23. The point beneath Earth's surface where rock breaks under stress and causes an earthquake
