Rocks and Minerals

Simon is observing slate, a metamorphic rock that splits into flat pieces. What causes the formation slate?

• Lava erupts and runs down the side of a Volcano
• Sediments are dspostied over time and become cemented
• Molten magma deep inside Earth
• A large amount of heat and pressure

Lilly has a rock in her collection that is very smooth and glassy. She knows that the rock was formed by lava that cooled very quickly after a volcanic Eruption. Which kind of rock does Lilly have? 

• Sedimentary Rock 
• Igneous Rock 
• Metamorphic Rock 
• Conrete Rock 

Ronny uses a hand lens to examine a piece of granite rock. He observes that the granite is made up of very large crystals. Which of the following is he viewing with his lens?

• Minerals 
• Fossils 
• Soil
• Shells 

George is testing some mineral properties to help him identify each mineral. For one test, he scrapes a mineral on a special plate to observe the color left behind. For which of the following properties of minerals is he most likely using this test? 

• Hardness
• Cleavage
• Luster
• Streak

Chelsea is conducting several test on minerals to help identify them. She uses a small hammer to break the mineral. Which property is she using to determine which mineral it might be. 

• Texture 
• Cleavage 
• Luster
• Streak 

Debbie tests the streak of two mineral samples using a streak plate. Both minerals leave a pale yellow streak. Which of the following might Debbie conclude about the two mineral samples? 

• They are both soft minerals
• They both have dull luster
• They are both very hard 
• They could be the same mineral

The students in Mrs. Ruiz's class are studying rocks. The students tell Mrs. Ruiz that several of their rocks are sedimentary. Which of the following could the students uses as evidence for their thinking? 

• The rocks contain fossils
• The rocks are very heavy
• The rocks have large crystals
• The rocks are grainy

Lauren and Ceazare observe the rock sample with a lot of clearly defined layers. Lauren thinks that the rock is metamorphic because it has layers. Ceazare believes the rock is sedimentary because it has layers. What is most likely the reason that Lauren and Ceazare do not agree on the classification of the rock.

• Lauren made a better observation
• Both rocks ALWAYS look the same
• Both types of rocks can have layers
• Ceazare has more evidence to supoort his observation

Prince is studying some rocks. One of the rocks has the imprints of shells in it. Which type of rock does Prince most likely have? 

• Igneous
• Sedimentary 
• Volcanic
• Metamorphic 

Michael is writing some observations of different samples in his mineral collection. Which of the following terms can both be used to describe luster?

• metallic and soft
• glassy and metallic
• 
  hard and coarse
• 
  grainy and rough
