(1) Only diamond contains radioactive carbon. (2) Only graphite consists of organic material (3) The minerals have different arrangements of carbon atoms. (4) The minerals have undergone different amounts of weathering. Which mineral is white or colorless, has a hardness of 2.5, and splits with cubic cleavage? 1) calcite 2) halite 3) pyrite 4) mica Name six properties that are useful in identifying minerals Color Cleavage/Fracture Luster Hardness Effervescence Magnetism Streak Density A student obtains a cup of quartz sand from a beach. A saltwater solution is poured into the sand and allowed to evaporate. The mineral residue from the saltwater solution cements the sand grains together, forming a material that is most similar in origin to (1) an extrusive igneous rock (2) a chemical sedimentary rock (3) a clastic sedimentary rock (4) a foliated metamorphic rock The diagram below represents the percentage by volume of each mineral found in a sample of basalt. Which mineral is represented by the letter X in the diagram? Plagioclase Feldspar Which rocks would most likely be separated by a transition zone of altered rock (metamorphic rock)? A) granite and limestone B) sandstone and limestone C) conglomerate and siltstone D) shale and sandstone The diagram below shows three beds of sediment deposited at different times in a quiet body of water. The sediment deposited in each bed is best described as A) sorted mainly according to particle shape B) a mixture of sorted and unsorted particles C) sorted mainly according to particle size D) showing no evidence of sorting Double Jeopardy! The cross-sectional diagram below shows a sediment-laden stream entering the ocean. The ocean is divided into four zones A, B, C, and D. Which change in the stream system would most likely cause the deposition of larger particles to be farther offshore? A) a decrease in the stream's gradient B) an increase in the density of large particles C) an increase in the stream's velocity D) a decrease in the quantity of large particles A large glass cylinder containing a mixture of sediments of the same density and water is shaken. Which drawing below best represents the result after settling? Complete the statement: Isotope A(n) _____________ is when any two or more forms of the same element differ in atomic mass. What fossils would most likely be found within the bedrock of south central New York State? (1)Mammals (2)Fishes (3)Dinosaurs (4)Birds A fine-grained igneous rock contains 11% plagioclase, 72% pyroxene, 15% olivine, and 2% amphibole. According to the Earth Science Reference Tables, this rock would most likely be classified as A) rhyolite B) gabbro C) basalt D) granite Final Jeopardy! Complete the following: Boron 5 10.81 5 6 5
