Across
- 2. places where plates slide sideways past each other.
- 8. the rigid outer part of the earth, consisting of the crust and upper mantle.
- 11. a scientific theory that explains how major landforms are created as a result of Earth's subterranean movements.
- 12. the force applied to a rock and may cause deformation.
- 13. a major geologic discontinuity or suture marking the juncture of lithospheric plates that have been joined by plate tectonics
- 14. a change in shape or size resulting from applied forces (deformation).
- 19. a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other
- 20. occurs when two tectonic plates move away from each other
- 21. the gradual movement of the continents across the earth's surface through geological time.
- 22. cause (rock strata) to undergo bending or curvature.
- 23. long chains of active volcanoes with intense seismic activity found along convergent tectonic plate boundaries.
- 24. formed from pre-existing rocks or pieces of once-living organisms.
Down
- 1. a cluster of parallel faults.
- 3. a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties.
- 4. a measure of its relative resistance to scratching, measured by scratching the mineral against another substance of known hardness on the Mohs Hardness Scale.
- 5. the equilibrium that exists between parts of the earth's crust, which behaves as if it consists of blocks floating on the und
- 6. a long, seismically active submarine ridge system situated in the middle of an ocean basin and marking the site of the upwell
- 7. started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form.
- 9. the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and
- 10. the study of the Earth's magnetic field preserved in rocks.
- 15. an opening in the Earth's crust through which lava, ash, and gases erupt.
- 16. a web of processes that outlines how each of the three major rock types—igneous, metamorphic, and sedimentary—form and break down based on the different applications of heat and pressure over time.
- 17. an extended break in a body of rock, marked by the relative displacement and discontinuity of strata on either side of a part
- 18. form when hot, molten rock crystallizes and solidifies.
- 20. a change in the shape or dimensions of a body, resulting from stress; strain.
