7. Why study rocks? … because rocks and minerals are involved in all of Earth’s processes like EARTHQUAKES, VOLCANOES, EROSION, AND MOUNTAIN BUILDING

8. Why study rocks? … because rocks provide clues about what Earth was like when and where they formed. …because rocks and minerals are resources used in every day life.

9. THE ROCK CYCLE ROCKS are any solid mass of mineral or mineral-like material occurring naturally There are ________________ of rocks classified by ___________________________ – _________________________________

10. THE ROCK CYCLE PREDICT WHICH ROCK TYPE GOES WITH WHICH PROCESS Sedimentary A. formed by the crystallization of molten magma or lava. Igneous B. formed by the alteration of pre-existing rock deep within Earth (but still in the solid state) by heat, pressure, and/or chemically active fluids. Metamorphic C. formed from the weathered products of preexisting rocks that have been transported, deposited, compacted, and cemented.

11.

16. Rock Cycle Practice In groups of 3 you will be tracing your way through the rock cycle Every group starts as MAGMA Roll the dice to determine what to do next – If you roll a 1 or 2… become an igneous rock – If you roll a 3 or 4… become a sedimentary rock – If you roll a 5 or 6… become a metamorphic rock Write down how you get from each roll to the next You MUST follow the correct processes to get between the rock types Each group must complete at least 6 turns
