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