Rock Types Challenge

How can you distinguish between an intrusive igneous rock and an extrusive igneous rock?

• Intrusive - larger crystals or coarse grained

  Extrusive- small crystals or fine grained.

• intrusive are organic and extrusive are inorganic.

• Intrusive are foliated and extrusive are non foliated.

• Intrusive are man made and extrusive are naturally occuring.

What type of rock do you have after a sedimentary rock is buried, melts completely, and then goes through the process of crystallization?

• Igneous

• Sedimentary

• Chemical

• Metamorphic

How are rocks and minerals related?

• Rocks are made up of 2 or more minerals.

• Minerals are part of rocks.

• Two or more rocks make a mineral

• Rocks and minerals are the same.

• Rocks are can be organic and minerals are not.

The process of one rock changing into another is called the

• geologic circle

• rock cycle

• rock round about

• rock genesis

Igneous rocks that are mafic have minerals that are

• dark colored

• light colored

• intermediate colored

• not colored

What are the steps to make a sedimentary rock?

• Erosion, weathering, compaction, and deposition

• Sediments, deposition, weathering, and erosion

• Heat, pressure, sediments, melting, and magma

• Weathering, sediments, erosion, deposition, and compaction/cementation

If you have an igneous rock that has light minerals in it then it has a color index called

• felsic

• phaneritic

• mafic

• vesicular

What are the three types of Sedimentary Rocks?

• Organic

• Foliated

• Intrusive

• Chemical

• Clastic

How are metamorphic rocks formed?

• weathering and erosion

• melting and cooling

• heat and pressure

• deposition and compaction

This type of metamorphic rock can have bands of light and dark minerals, large mineral crystals, or layers.

• clastic

• foliated

• non foliated

• clastic
