Question 1 1. Which of the following statements is false ? Formation of table salt: Answer is, in mineralogic terms, formation of the halide halite. takes place when a solution has become saturated. is an example of solidification of a melt. needs a seed crystal to begin. results in cubic crystals. Question 2 1. Calcite and aragonite minerals that constitute clam shells are examples of which method of mineral formation? Answer solidification of a melt precipitation from a solution solid-state diffusion biomineralization fumerolic mineralization Question 3 1. Silicates: Answer have the silicon-oxygen tetrahedron as their structural unit. are a major component of continental crust. are classified on the basis of how the tetrahedrons join and share oxygen atoms. are a huge category of minerals and include the common minerals quartz and feldspar. all of the above. Question 4 1. Which of the following statements is false ? Crystals: Answer have an orderly internal arrangement of atoms patterned as if attached to an imaginary framework called a crystal lattice. grow outward from a seed. are formed by the high-temperature, extremely rapid process known as solid-state diffusion. display symmetry. cause X-ray diffraction.

Which of the following is not a mineral? Answer Glacial ice, because ice isn’t a rocky material. Salt, because it’s not crystalline. A gold nugget, because it’s a native metal. Pyrite, because it’s a chemical compound. Oil, because it’s a liquid, not a solid. Question 6 1. The tendency of a mineral to break and produce smooth, curving shell-shaped surfaces is termed: Answer luster. fibrous fracture. conchoidal fracture. streak. perfect cleavage. Question 7 1. There are two physical properties of minerals that both result in smooth, flat surfaces with specific angles between them. The first property is the result of how the mineral forms; the second is the result of breaking a sample of the mineral. These properties are called: Answer hardness and cleavage. cleavage and hardness. crystal form and cleavage. cleavage and crystal form. crystal form and hardness. Question 8 1. Which is not a physical property commonly used in the lab or field to identify minerals? Answer color streak luster diffraction specific gravity Question 9
