1FINAL REVIEW: ROCKS & MINERALS 4. Igneous rocks are formed by:(1) weathering (3) volcanic activity(2) cementation (4) sedimentation1. Which statement is true of all rocks?(1) Rocks contain organic material.(2) Rocks contain fossils.(3) Rocks are composed of minerals.(4) Rocks are formed in layers.5. If shell fragments are found in a rock sample, it is most likely that the rock formed:(1) on a mountain slope (3) on a glacier(2) from magma (4) in shallow water2. Weathering and erosion of Earth’s crust areprimarily caused by(1) gravity (3) evaporation(2) volcanic activity (4) sedimentation3. The diagram below shows a rock sampleand an identification key.6. In which type of rock are fossils generally found?(1) igneous (3) sedimentary(2) metamorphic (4) volcanic7. Dust and ash entering the atmosphere as a resultof volcanic eruptions can affect Earth’s(1) tidal activity (3) weather and climate(2) rotation and revolution (4) orbital shapeNatural CementKeyShell fragment Feldspar fragmentQuartz fragment8. Rocks are classified as igneous, metamorphic,or sedimentary according to:(1) their color (3) how they formed(2) their shape (4) the minerals they containThis rock sample would best be classified as(1) volcanic (3) metamorphic(2) sedimentary (4) igneous9. Rocks formed by heat & pressure are:(1) igneous (3) metamorphic(2) sedimentary (4) plutonic

1142. Explain why hardness is a valuable property of some minerals. *Base your answers to questions 42 through 44 on the information below.Gems & Minerals: There are about 4,000 types of minerals on Earth. Of these, only about 15 are used to make gems. Gems are minerals that may have been cut & polished to make them sparkle. The diamond is the hardest natural substance we know. Diamonds form deep underground at very high temperature & pressure conditions caused by the overlying thick layers of rock that squeeze the carbon atoms into a tight, strong crystal. Diamonds might grow under these conditions for 1 billion to 3 billion years & therefore are considered the oldest gemstone. Only about 20 percent of diamonds are made into jewels. Because they are so hard, most diamonds are used to make tools such as dental drills & metal cutters.42. Explain why hardness is a valuable property of some minerals.________________________________________________________________________________________43. Identify one physical property, other than hardness, that may add to the beauty of a gemstone._______________________________________________________________________________________THEY ARE USED TO MAKE TOOLS & OTHER USEFULPRODUCTS BECAUSE OF THEIR HARDNESS.ITS COLOR, LUSTER & CRYSTAL SHAPE.,44. When diamonds are shipped to jewelry stores, they are individually wrapped in paper. Explain why the paperis needed to protect each diamond from damage._______________________________________________________________________________________BECAUSE THEY CAN SCRATCH EACH OTHER.
