plate tectonics
Across
- 7. the chemical and physical process that breaks down rock at the earths surface.
- 9. the force that occurs at a transform boundary.
- 12. the theory that the continents slowly move across earths surface
- 14. A line on a topographic map that connects points of equal elevation.
- 15. the study of the solid earth.
- 16. The process by which sediments are pressed together under the own weight.
- 17. a break or crack in the earth’s lithosphere along which rocks move.
- 19. Small, solid particles of material from rocks or organisms that are moved by water or wind, resulting in erosion and deposition.
- 20. A series of processes on the surface and inside Earth that slowly changes rocks from one kind to another.
- 22. the type of rock that is formed when heat & pressure is applied to it.
- 23. The process by which water, ice, wind, or gravity moves fragments of rock and soil.
Down
- 1. a plate boundary where two plates move away from each other
- 2. the process when oceanic crust sinks beneath a continental crust.
- 3. a plate boundary where two plates move towards each other.
- 4. Stress that squeezes rock until it folds or breaks
- 5. The layer of hot, solid materials between Earth’s crust and core.
- 6. the layer of rock that forms earths outer surface.
- 8. a plate boundary where two plates move past other in opposite dirctions.
- 10. the transfer of thermal energy by movements of a fluid.
- 11. a type of map usually using contour lines that shows natural features on the earth’s surface.
- 13. a type of rock that forms from the cooling of molten rock at or below the surface.
- 18. the force that occurs at a divergent boundary
- 21. the process by which sediment settles out of the water or wind the is carrying it and is deposited in a new location.
