Geology

3. The San Andreas ______ fault in California extends roughly 750 miles along a transverse plate boundary!
4. the outermost solid shell of our rocky planet.
6. hot molten rock erupted from a volcano or fissure.
9. Last name of the German scientist who first proposed the theory of plate tectonics.
10. The scientific study of Earth (not just rocks!)
12. The majority of Earth's volcanos and earthquakes occur along the Ring of ______.
14. layer inside a planetary body bounded below by a core and above by a crust
15. The most common mineral in Earth's crust.
17. rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors
18. ________ crust is denser and thinner of the two types of crust
20. Mountains are formed at this type of tectonic plate boundary.
21. ________ crust is lighter and thicker of the two types of crust.
22. the remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock.
24. the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.
25. Solid inorganic naturally occurring compounds that have distinct organized compositions

1. when one plate in plate tectonics (usually the denser one) is push below the other.
2. Horizontal layer of mostly rock sediments
5. Name of the supercontinent from when all the landmasses were joined together
7. Molten rock material found below Earth's surface
8. is the breaking down or dissolving of rocks and minerals on Earths surface.
11. The ____ core is the only liquid layer, and is mainly made up of the metals iron and nickel.
13. 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.
16. A divergent plate boundary can result in this geological feature such as the "Great" one in Africa or the one in the Mid-Atlantic.
19. Rocks formed by the cooling and solidifying of molten materials
23. The ____ core is the solid, mostly iron, center of our planet.
