Oxford Middle School Mr. Vickery’s 6 th Grade Science

LET’S GET READY TO PLAY, WHO WANTS TO BE A SCIENCE WIZARD!!

A:B: CrystalsRocks #1 What is Earth’s crust made of? C:D: MineralsSoil

B. Rocks

A:B: TextureMineral composition #2 Which of these do geologists use to classify rocks? C:D: HardnessColor

A.Texture C. Hardness D. Color

A:B: QuartzMica #3 Which of these minerals are found in granite? C:D: FeldsparHornblende

A, B, C, D Quartz, Feldspar, Mica, and Hornblende

A:B: Shearing Deposition #4 What forces move rocks through the rock cycle? C:D: ErosionCompression

B and C Deposition and Erosion

A:B: Plate TectonicsRock Cycle #5 A series of processes that slowly changes rocks from one kind to another is called? C:D:

B. Rock Cycle

TrueFalse #6 True/False All rocks follow the same pathway through the Rock Cycle.

False Each rock can create a different rock

#7 What are rocks made of?

They are made of mixtures of minerals and other materials.

TrueFalse #8 True/False Most rocks can be identified by color alone.

False It only gives you a way to predict what it may be.

A:B: An example of a coarse-grained rock is diorite An example of a fine- grained rock is slate #9 What is true about the grain size in rock? C:D: Grains in fine-grained rock are easy to see Grains in coarse- grained rock are microscopic

A AND B

A:B: GrainsCrystals #10 Particles of minerals and other rocks that make up a rock are called C: Fossils

A Grains

TrueFalse #11 True/False A rock’s grains give the rock its texture.

True

A:B: The thickness of the rock when measured How a rock feels in your hand #12 Which choice(s) defines texture? C:D: The look of a rock

B and C

Igneous RockMetamorphic Rock #13 Sedimentary Rock What type of rock forms from the cooling of magma and lava

IGNEOUS ROCK

Igneous RockMetamorphic Rock #14 Which rock forms in layers of particles of rock? Sedimentary Rock

Sedimentary Rock

#15 True/False Metamorphic rocks form close to the surface

False Deep Underground

Igneous RockMetamorphic Rock #16 This type of rock forms when existing rock is changed Sedimentary Rock

Metamorphic Rock

Shape of the rock’s crystals Size of the rock’s crystals #17 What determines the grain shape of a rock such as granite? Shape of fragments of other rock Coarseness of the rock’s grains

A. Shape of the rock’s crystals

Some rocks without crystal grains cooled very quickly Some rocks have no visible grain even under a microscope #18 What is true about rocks with no visible grain? Rocks without crystal grains look rough and coarse An example of a rock with a glassy texture is slate

B Some rocks have no visible grain even under a microscope

A:B: Fineness of the rock’s grains Size of the rock’s grains #19 What determines the grain shape of a rock such as conglomerate? C:D: Shape of the rock’s crystals Shape of fragments of other rock

A

A:B: It looks like different colors in bands It looks like a stack of pancakes #20 What describes the grain pattern of gneiss? C:D: It looks like waves It looks like rows of squares and rectangles

A. It looks like different colors in bands

A:B: #21 How do geologists classify a rock? C:D:

Geologists classify into three major groups: igneous, sedimentary, and metamorphic

Great Job!!!! Great Job!!!! Thank you for playing! Thank you for playing!
