Chapter 2, Section 1: The Rock Cycle 1. Define rock. _________________________________________________________________________________ 2. What is the continual process by which new rocks forms from old rock called? ____________________________ 3. How have human used rocks throughout history? ___________________________________________________ PROCESSSES THAT SHAPE THE EARTH 4. Define weathering. ___________________________________________________________________________ 5. One reason that weathering is so important is because it breaks rock down into fragments or, ______________________________, from which sedimentary rocks are made. 6. Define erosion. _______________________________________________________________________________ 7. Define deposition. ____________________________________________________________________________ 8. Sedimentary rock can be made when sediment is pressed and cemented together by ______________________ dissolved in water. 9. How can buried sediment turn into sedimentary rock? _______________________________________________ _______________________________________________________________________________________________ 10. What two different scenarios can occur if the temperature and pressure surrounding sediment are high enough? _______________________________________________________________________________________________ _______________________________________________________________________________________________ 11. Define uplift. ________________________________________________________________________________ ILLUSTRATING THE ROCK CYCLE Match the correct definition with the correct term. Write the letter in the space provided. 12. Magma in the Earth’s crust that has risen to the surface and cools and solidifies a. magma 13. Rock that is forced downward and is exposed to heat and pressure b. sediment 14. Rocks that are partially or completely melted c. igneous rock 15. Igneous rock at the Earth’s surface that is weathered and wears away d. sedimentary rock 16. Sediment that washes down into rivers and oceans and is pressed and cemented together e. metamorphic rock ROUND AND ROUND IT GOES 17. Use the space below to illustrate the rock cycle. (Use a separate piece of paper in necessary.) 18. What forces affect rock deep beneath the earth’s surface? ___________________ and _____________________ 19. A rock at the earth’s surface is primarily affected by forces of __________________ and ___________________ ROCK CLASSIFICATION 20. Beyond the three basic types of rock, rocks can be based into subcategories based on what two other characteristics. _____________________________ and _______________________________. 21. What determines the composition of a rock? ______________________________________________________. 22. Explain the difference between a chemical analysis and a physical analysis of the composition of a rock. ___________________________________________________________________________________________ ___________________________________________________________________________________________ 23. A rock that consists mostly of the mineral quartz will have a composition very similar to ___________________. 24. What characteristics is a rock’s texture based on? ___________________________________________________________________________________________. 25. What factors can affect the texture of a sedimentary rock? __________________________________________________________________________________________. 26. What factors can affect the texture of an igneous rock? __________________________________________________________________________________________. 27.
