100

Explain inorganic. never came from living things

never came from living things

200

What is a mineral’s color determined by (test for the powder)?

streak test- scratch against a ceramic plate

streak test- scratch against a ceramic plate

300

What are hardest and softest known minerals?

10-diamond, 1-talc

400

Explain definite chemical composition.

made up of certain properties and proportions

500

Do most minerals break apart evenly? 

What is this called when they don’t? 

no

fracture 

Minerals

100

If a mineral has volume and shape, it’s known as being what?

a solid

200

Explain naturally occurring.

it happens naturally, not manufactured

300

Explain luster.

how a mineral shines/reflects light

400

(Use the Mohs Hardness Scale)

Your friend shows off her new diamond ring. You reach out and accidentally scratch it with your fingernail. Is it a real diamond ring? Explain why or why not.

No, a diamond can't be scratched by a fingernail. A diamond is the hardest known mineral.

500

(Use the Mohs Hardness Scale)

Your friend shows off her new apatite ring. You reach out and accidentally scratch it with your topaz ring. Is it a real apatite ring? Explain why or why not. 

Yes, or at least it can be because apatite is lower on the Mohs Hardness Scale and can be scratched by the higher topaz ring.

Rocks

100

What is true of all rocks? 

they are all made up of minerals

200

Name the three types of rocks.

sedimentary rock

igneous rock

metamorphic rock

300

To describe a rock’s texture, geologists determine what?

the size, shape, and pattern of the rock’s grains.

400

Rock that forms from the cooling of magma below the surface or lava at the surface is called what?

igneous rock

500

Magma that cools very slowly deep beneath the surface forms minerals with what type of crystals? 

large because they cool slowly

Rock Cycle

100

Use your rock cycle diagram-

Two conditions that can cause sedimentary rock to change to metamorphic rock are what? 

heat and pressure

200

Use your rock cycle diagram-

Heat and pressure deep beneath Earth’s surface can change any rock into what? 

metamorphic rock

300

Use your rock cycle diagram-

How is magma formed?

   

melting

400

Use your rock cycle diagram-

What process is necessary to change a sedimentary rock to a metamorphic rock? 

heat and pressure, metamorphism

500

Use your rock cycle diagram-

Name three processes that occur in the rock cycle.

name any three

Rock Cycle

100

Use your rock cycle diagram-

How does igneous rock become metamorphic rock?

heat and pressure, metamorphism

200

Use your rock cycle diagram-

How does a metamorphic rock become an igneous rock?

   

melting, magma, solidification

300

Use your rock cycle diagram-

How are sediments formed?

   

weathering and erosion

400

Use your rock cycle diagram-

How does magma become igneous rock?

   

solidification

500

Use your rock cycle diagram-

How do sediments become sedimentary rock?

   

deposition and burial, compaction and/or cementation
