MR. SURRETTE VAN NUYS HIGH SCHOOL CHAPTER 1: ROCKS AND MINERALS QUIZ SOLUTIONS 1. This rock changes from one kind to another as a result of high temperature or pressure: 1A. metamorphic 2. This mineral scratches topaz: 2A. corundum 3. An unreliable means of identifying minerals is: 3A. color 4. A sequence of events involving the formation, destruction, alteration, and reformation of rocks: 4A. rock cycle 5. The most common metamorphic rocks include: 5A. slate 6. The process by which rock particles are transported by water, wind, or ice: 6A. erosion 7. What is the density of gold if 57.90 grams fit inside a 2.5 cm3 cube? 7A. (1) = M / V (2) = 57.90 g / 2.5 cm3 (3) = 19.3 g/ cm3 8. The most abundant element found in minerals is: 8A. oxygen 9. The most abundant mineral group on earth’s crust is: 9A. silicates 10. The most common igneous rocks include: 10A. basalt 11. The most common sedimentary rocks include: 11A. shale 12. Metamorphism caused by stress, such as increased pressure: 12A. mechanical deformation 13. A naturally formed, inorganic solid compound in an ordered array of atoms: 13A. mineral 1|Page INTEGRATED SCIENCE MR. SURRETTE VAN NUYS HIGH SCHOOL 14. Minerals that have the same chemical composition but different crystal structure: 14A. polymorphs 15. Rocks that crystallize below the earth’s surface: 15A. intrusive 16. Metamorphism caused by high temperatures: 16A. recrystallization 17. Fossils most often form in __________ rock. 17A. sedimentary 18. The process by which a single magma can generate several different igneous rocks is: 18A. fractional crystallization 19. Metamorphism that occurs when a body of rock is intruded by magma: 19A. contact 20. What size cube will exactly hold 20 grams of chromite (density = 4.6 g/cm3)? 20A. (1) = M / V (2) V = M / (3) V = 20 grams / 4.6 g/cm3 (4) V = 4.35 cm3 2|Page INTEGRATED SCIENCE
