TEACHER RESOURCE PAGE 25. E Chapter Test B 1. stratification 2. nonfoliated rock 3. erosion 4. composition 5. rock cycle 6. A 7. C 8. D 9. D 10. Answers will vary. Sample answer: Clastic sedimentary rock is formed from rock fragments that are cemented together by calcite or quartz. Chemical sedimentary rock is made of dissolved minerals that eventually crystallize. 11. Answers will vary. Sample answer: Contact metamorphism occurs when magma comes into direct contact with rock. Regional metamorphism occurs when large pieces of the Earth s crust collide with each other. 12. Answers will vary. Sample answer: Under a microscope a nonfoliated rock will not have mineral grains that are aligned. 13. Answers will vary. Sample answer: Limestone is formed from the remains, or fossils, of animals that once lived in the ocean. 14. Answers will vary. Sample answer: Rocks recrystallize when the crystals of the minerals change in composition. 15. Rocks like granite and marble are good building materials because they can withstand weathering for long periods of time. 16. Answers will vary. Sample answer: An extrusive rock formation reveals that there is a lot of activity, perhaps volcanic, going on below the Earth s surface. 17. All three rock types weather when they are uplifted to the earth s surface, forming sediments that cover the Earth s surface 18. a. igneous rock b. composition c. texture d. dikes e. erode f. conglomerate g. sedimentary rock Chapter Test C 1.
