Rocks & Minerals Study Guide 1.Sharon 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 graph D. Heat a rock in an oven. 2.Which is a scientist who studies rocks and minerals? A. Biologist B. Geologist (p. 47) C. Meteorologist D. Chemist 3.Which item would NOT help you to observe the properties of minerals? A. Paper clip – can scratch or magnetic B. Penny – can scratch C. Thermometer D. Hand lens – closer look 4. Jerry 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 1 B. Luster C. Streak D. Cleavage 5.A solid material made up of one or more minerals is A. a shell B. a rock – a, c, and d are all possible ingredients OF a rock! C. sediment D. soil Name: _______________________________ # _________ Date: ______________________
6. 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. 7. Which causes sedimentary rock to change into metamorphic rock? A. Weathering and pressure B. Cooling and hardening C. Cementing and weathering D. Heat and pressure – other choices Are on p. 43! 8. Molten rock becomes igneous rock when molten rock A. cools and hardens B. is pressed into layers C. melts D. weathers 9. Which property can be used to tell if a mineral is metallic or nonmetallic? A. Cleavage B. Hardness C. Luster D. Color 10. Why does Sharon wear goggles when she tests mineral properties? A. To see the minerals more clearly B. To make the minerals look larger C. To block out light D. To protect her eyes – ‘test’ woud be scratching ; powder may fly. 11. The students in a class tested the properties of a mineral. They recorded their observations in a chart.

Keep his observations the way he recorded them. (He may be the RIGHT one!!) D. Change what he recorded to match others’ results.
