1. Silicate minerals contain the elements silicon and oxygen. Which list contains only silicate materials? 1) graphite, talc, and selenite gypsum 2) potassium feldspar, quartz, and amphibole 3) calcite, dolomite, and pyroxene 4) biotite mica, fluorite, and garnet 2. Which is the major component of drywall? 1) talc 2) calcite 3) muscovite mica 4) selenite gypsum 3.

The diagrams below represent the shape and type of of two different minerals.

The crystal shape and type of cleavage of these two minerals are determined mainly by the minerals' 1) color and type of luster 2) and hardness 3) composition and atomic arrangement 4) density and magnetism Minerals

6. Which mineral can scratch A, B, and C, but can not scratch D? 1) talc 2) selenite gypsum 3) fluorite 4) quartz 7. The diagram below represents a sample of mineral A.

Mineral A is most likely 1) garnet 2) 3) olivine 4) halite

8. Which two properties are most useful in distinguishing between galena and halite? 1) cleavage and color 2) luster and color 3) hardness and streak 4) streak and cleavage Minerals

Base your answers to questions 9 and 10 on the data table below, which lists some properties of four minerals that are used as ores of (Zn).

9. Which mineral belongs in the same mineral group as quartz and olivine? 1) zincite 2) 3) sphalerite 4) smithsonite 10. A mineral with a hardness of 5 would scratch 1) all four zinc minerals in the table 2) zincite, but not sphalerite, smithsonite, or willemite 3) zincite and sphalerite, but not smithsonite or willemite 4) zincite, sphalerite, and smithsonite, but not willemite Minerals

Base your answers to questions 11 and 12 on the diagram below, which shows the results of three different physical tests, A, B, and C, that were performed on a mineral.

11. The luster of this mineral could be determined by 1) using an electronic balance 2) using a graduated cylinder 3) observing how light reflects from the surface of the mineral 4) observing what happens when acid is placed on the mineral 12. Which mineral was tested? 1) amphibole 2) quartz 3) galena 4) graphite

13. How are the minerals biotite mica and muscovite mica different? 1) Biotite mica is colorless, but muscovite mica is not. 2) Biotite mica contains iron and/or magnesium, but muscovite mica does not. 3) Muscovite mica scratches quartz, but biotite mica does not. 4) Muscovite mica cleaves into thin sheets, but biotite mica does not. 14. Which mineral is composed of Calcium and Fluorine? 1) Amphiboles 2) Calcite 3) Hematite 4) Fluorite Minerals

15. Base your answer to the following question on the table below which provides information about the crystal sizes and the mineral compositions of four igneous rocks, A, B, C, and D.

The mineral quartz in rock A is composed of the two most abundant elements by mass in Earth's crust. These two elements are oxygen and 1) magnesium 2) silicon 3) iron 4) lead 16. The diagrams below show the crystal shapes of two 17. The diagram below shows how a sample of the minerals. mineral mica breaks when hit with a rock hammer.

This mineral breaks in smooth, flat surfaces because it 1) is very hard 2) is very dense 3) contains large amounts of iron Quartz and halite have different crystal shapes 4) has a regular arrangement of atoms primarily because 18. In order to make observations, an observer must 1) light reflects from crystal surfaces always use 2) energy is released during crystallization 1) experiments 3) of impurities that produce surface variations 2) the senses 4) of the internal arrangement of the atoms 3) proportions 4) mathematical calculations Minerals

19. Which statement about a rock sample is most likely Base your answers to questions 24 through 26 on the an inference? diagrams below, which represent two different solid, uniform materials cut into cubes A and B. 1) The rock has flat sides and sharp corners. 2) The rock is made of small, dark-colored . 3) The rock has thin, distinct layers. 4) The rock has changed color due to weathering. 20. Base your answer to the following question on the image provided below.

24. What is the mass of cube B? 1) 9 g 2) 27 g 3) 3 g 4) 81 g 25. If a parcel of air is heated, its density will 1) decrease 2) increase 3) remain the same If each side of the cube shown above has the same 26. Assume cube B was broken into many irregularly length as the measured side, what is the approximate shaped pieces. Compared to the density of the entire volume of the cube? cube, the density of one of the pieces would be 1) 2.20 cm3 2) 4.84 cm3 1) less 2) greater 3) 6.60 cm3 4) 10.65 cm3 3) the same 21. The diameter through the equator of Jupiter is about 143,000 kilometers. What is this distance written in 27. The data table below shows the mass and volume of scientific notation (powers of 10)? four different minerals. 1) 143 × 102 km 2) 1.43 × 103 km 3) 1.43 × 105 km 4) 143 × 105 km 22. Which term is best defined as a measure of the amount of space a substance occupies? 1) mass 2) volume 3) density 4) weight Which mineral has the greatest density? 23. A student incorrectly measured the volume of a 1) A 2) B 3) C 4) D mineral sample as 83 cubic centimeters when the actual volume was 89 cubic centimeters.
