Top of Form Question 1 (Multiple Choice Worth 1 points) [RM.01]The chart below shows the amount of coal mined in four different states of USA in the year 2005. State Amount of coal mined (in billion tons) West Virginia 37 Wyoming 68 Montana 120 Illinois 78 In which state was more than 100 billion tons of coal mined in 2005? Illinois Montana Wyoming West Virginia Question 2 (Multiple Choice Worth 1 points) [RM.01]The map below shows the minerals found in different parts of the world. Based on the map, which of the following countries mines the most coal? Argentina Brazil China United States Question 3 (Multiple Choice Worth 1 points) [RM.01]Look at the minerals shown below. Uranium: © 2010 Kgrr Creative Commons elements combine due to high pressure water solidifies due to drop in temperature atoms break up after a chemical reaction magma cools after a volcanic eruption Question 4 (Multiple Choice Worth 1 points) [RM.01]One student did an experiment with salt water. The steps of the experiment are shown below. · Pour half a cup of salt water into a pan. · Keep the pan outside in the sun for a day. · Allow all the water in the pan to evaporate. · Observe a white residue at the bottom of the pan. The student’s experiment demonstrates that when water evaporates, it changes into solid minerals leaves solid minerals behind turns solid minerals into powder converts gases into solid minerals Question 5 (Multiple Choice Worth 1 points) [RM.01] iron and water plants and water gold and bauxite concrete and bauxite Question 6 (Multiple Choice Worth 1 points) [RM.01] The copper wire is cut into three pieces of unequal lengths. All three pieces of copper would have the same mass the same physical properties different crystal structures different arrangement of atoms Question 7 (Multiple Choice Worth 1 points) [RM.01] nails wires paints drains Question 8 (Multiple Choice Worth 1 points) [RM.01] Mineral Talc Gypsum Calcite Fluorite Apatite Orthoclase Hardness 1 2 3 4 5 6 Any mineral on the hardness scale would scratch minerals below it on the scale. The student tested Mineral 1 and observed that it could scratch only two other minerals on the hardness scale. It was observed that Mineral 2 could scratch only four other minerals on the hardness scale. Which of these is a correct conclusion the student can make about Mineral 1 and Mineral 2? Mineral 1 can be used to scratch talc and Mineral 2 can be used to scratch orthoclase. Mineral 1 can be used to scratch orthoclase and Mineral 2 can be used to scratch talc. Mineral 1 can be used to scratch calcite and Mineral 2 can be used to scratch gypsum. Mineral 1 can be used to scratch gypsum and Mineral 2 can be used to scratch calcite. Question 9 (Multiple Choice Worth 1 points) [RM.02]Look at the diagram shown below. Which of these statements best summarizes the information provided by the diagram? Melting changes all types of rocks directly into magma. Heat and pressure change all types of rocks directly into magma. Weathering and erosion change all types of rocks directly into sediments. Compaction and cementation change all types of rocks directly into sedimentary rocks. Question 10 (Multiple Choice Worth 1 points) [RM.02]Look at the diagram shown below. Which of these charts best classifies Rock 1, Rock 2, and Rock 3? Name of rock Rock 1 Rock 2 Rock 3 Type of rock Sedimentary rock Metamorphic rock Igneous rock Name of rock Rock 1 Rock 2 Rock 3 Type of rock Metamorphic rock Sedimentary rock Igneous rock Name of rock Rock 1 Rock 2 Rock 3 Type of rock Igneous rock Sedimentary rock Metamorphic rock Name of rock Rock 1 Rock 2 Rock 3 Type of rock Metamorphic rock Igneous rock Sedimentary rock Question 11 (Multiple Choice Worth 1 points) [RM.02]The picture below shows sedimentary rocks on the Earth’s surface. The sedimentary rocks were formed by the chemical reactions under water accumulation of eroded rocks melting of rocks under the ground cooling and crystallization of magma Question 12 (Multiple Choice Worth 1 points) [RM.02]The diagram below shows a process Y in the formation of rocks. Which of these best represents the sequence of steps in the process Y? heating melting crystallization weathering melting lithification heating pressure crystallization weathering deposition lithification Question 13 (Multiple Choice Worth 1 points) [RM.02]One student made this incorrect diagram of the rock cycle. Which of these statements best describes a method to correct the diagram? Interchange the labels inside ovals A and B. Interchange the labels inside ovals A and C. Interchange the labels on the arrows 5 and 1. Interchange the labels on the arrows 2 and 4. Question 14 (Multiple Choice Worth 1 points) [RM.02]The diagram below shows a portion of the rock cycle. Which statement best describes P and Q in the diagram? P represents melting and Q represents igneous rocks. P represents pressure and Q represents sedimentary rocks. P represents crystallization and Q represents igneous rocks. P represents transportation and Q represents sedimentary rocks. Question 15 (Multiple Choice Worth 1 points) [RM.02]One student did an experiment on the rock cycle. The steps of the experiment are shown below. · Pile wax shavings of different colors one over the other. · Hold the pile of colored wax shavings in the palm and squeeze it for two to three minutes. · Fold the pile and squeeze it in the palm again for a minute. · Place the pile in a metal pan and heat until all the wax melts. · Cool the wax overnight. What does the student’s experiment most likely demonstrate about the rock cycle? Heat can melt metamorphic rocks into magma, which solidifies to form igneous rocks. Melting can convert igneous rocks into magma, which cools to form metamorphic rocks. Pressure can solidify sediments into igneous rocks, which change into magma on being heated. Lithification can change sediments into sedimentary rocks, which change into metamorphic rocks on being heated. Question 16 (Multiple Choice Worth 1 points) [RM.04]The picture below shows a soil texture triangle. Based on the soil texture triangle, how much clay is present in sandy clay loam? 0 percent to 20 percent 20 percent to 35 percent 40 percent to 55 percent 60 percent to 80 percent Question 17 (Multiple Choice Worth 1 points) [RM.04]Which of these Earth spheres interact when glaciers carry the top soil from one place to another? atmosphere and geosphere atmosphere and hydrosphere cryosphere and geosphere cryosphere and hydrosphere Question 18 (Multiple Choice Worth 1 points) [RM.04] The pictures below represent three soil profiles. Which of these statements is correct about the soil profiles? Profile A is formed after Profile B. Profile B is formed after Profile C. Profile A and Profile B are formed before Profile C. Profile B and Profile C are formed before Profile A. Question 19 (Multiple Choice Worth 1 points) [RM.04]Soil forms because of the decaying of organic matter erosion of rocks and minerals solidification of organic matter weathering of rocks and minerals Question 20 (Multiple Choice Worth 1 points) [RM.04]Look at the pictures below. Which of these is most likely represented by the three pictures? types of erosion that form soil types of decaying that form soil physical weathering that forms soil chemical weathering that forms soil YOU MUST CHECK THE BOX BELOW PRIOR TO SUBMITTING YOUR EXAM!
