Rocks and Minerals

A student is testing a mineral.

Which mineral property is being tested in the diagram?

• Cleavage

• Hardness

• Streak

In the diagram of the rock cycle above, which processes are represented at X, at Y, and at Z?

• X=melting

  Y=cooling

  Z= weathering

• X=cooling

  Y=melting

  Z=weathering

• Z=Cooling

  X= Weathering

  Y=melting

One type of rock can be formed from the melting of all other types of rocks. This image shows lava as a result of the melting rock. This lava will cool into which classification of rock?

• Sedimentary rock

• Extrusive igneous rock

• Metamorphic rock

• Intrusive igneous

How are rocks classified

• By where they are found

• by size

• by color

• by how they are formed

How are metamorphic rocks formed?

• By heat and pressure

• when other rocks melt and cool

• from sediments that are compacted together

How are igneous rocks formed

• when a metamorphic rock melts

• by sediments of other rocks that get compacted together.

• when magma or lava cool and solidify
