Across
- 5. ________ crust is denser and thinner of the two types of crust
- 7. A divergent plate boundary can result in this geological feature such as the "Great" one in Africa or the one in the Mid-Atlantic.
- 9. when one plate in plate tectonics (usually the denser one) is push below the other.
- 11. The San Andreas ______ fault in California extends roughly 750 miles along a transverse plate boundary!
- 14. Rocks formed by the cooling and solidifying of molten materials
- 18. Solid inorganic naturally occurring compounds that have distinct organized compositions
- 19. The ____ core is the only liquid layer, and is mainly made up of the metals iron and nickel.
- 21. is the breaking down or dissolving of rocks and minerals on Earths surface.
- 23. Molten rock material found below Earth's surface
- 24. The ____ core is the solid, mostly iron, center of our planet.
Down
- 1. Mountains are formed at this type of tectonic plate boundary.
- 2. Plate _______ is a theory in geology: the lithosphere of the earth is divided into plates that float on & travel independently over the mantle. Earth's seismic activity occurs at the boundaries of these plates.
- 3. Name of the supercontinent from when all the landmasses were joined together
- 4. The most common mineral in Earth's crust.
- 6. the outermost solid shell of our rocky planet.
- 8. ________ crust is lighter and thicker of the two types of crust.
- 10. the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.
- 12. hot molten rock erupted from a volcano or fissure.
- 13. Horizontal layer of mostly rock sediments
- 15. The majority of Earth's volcanos and earthquakes occur along the Ring of ______.
- 16. Last name of the German scientist who first proposed the theory of plate tectonics.
- 17. the remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock.
- 20. rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors
- 22. The scientific study of Earth (not just rocks!)
- 23. layer inside a planetary body bounded below by a core and above by a crust
