1 Rocks & Minerals Study Guide Name: _______________________________ # _________ Date: ______________________Rocks & Minerals Study GuideSharon wants to explain the rock cycle to a classmate. Which is the BEST way for her to do this?A. Draw the rock cycle. (p. 43)B. Show the classmate a rock.C. Make a graphD. Heat a rock in an oven.Which is a scientist who studies rocks and minerals?A. BiologistB. Geologist (p. 47)C. MeteorologistD. ChemistWhich item would NOT help you to observe the properties of minerals?A. Paper clip – can scratch or magneticB. Penny – can scratchC. ThermometerD. Hand lens – closer lookJerry has an unknown mineral sample. Which is NOT a property he can use to identify the mineral?A. Size – NOT a property ; others in lesson 1B. LusterC. StreakD. Cleavage5. A solid material made up of one or more minerals isA. a shellB. a rock – a, c, and d are all possible ingredients OF a rock!C. sedimentD. soil
2 A. Weathering and pressure Which is true about a diamond?A. It is made of calcium.B. It is the hardest mineral. (10 on Mohs – p. 18)C. It is a nonmetallic mineral.D. It can be scratched by talc.Which causes sedimentary rock to change into metamorphic rock?A. Weathering and pressureB. Cooling and hardeningC. Cementing and weatheringD. Heat and pressure – other choices Are on p. 43!Molten rock becomes igneous rock when molten rockA. cools and hardensB. is pressed into layersC. meltsD. weathers9. Which property can be used to tell if a mineral is metallic or nonmetallic?A. CleavageB. HardnessC. LusterD. ColorWhy does Sharon wear goggles when she tests mineral properties?A. To see the minerals more clearlyB. To make the minerals look largerC. To block out lightD. To protect her eyes – ‘test’ woud be scratching ; powder may fly.The students in a class tested the properties of a mineral. They recordedtheir observations in a chart. Then they wrote reports. Some of Juan’sobservations did not match those of the rest of the class. What should Juando?A. Throw away his report.B. Erase what he recorded.C. Keep his observations the way he recorded them. (He may be the RIGHT one!!)D. Change what he recorded to match others’ results.
