Rocks Rock

The age of a rock sample can be determined by finding the relative amount of a parent isotope that has changed into a daughter isotope within the sample. Which property of radioactive decay allows the age of the rock to be determined in years?

• releases energy

• releases energy

• happens in all rocks

• happens at a set rate

In the Starburst Lab, we made models of all types of rocks. Which type of rock is able to turn into a metamorphic rock?

• Only sedimentary

• Only igneous

• Both igneous and sedimentary

• Neither igneous or sedimentary

What must happen to a metamorphic rock before it becomes a sedimentary rock rock?

• It must be broken down into sediment

• It must be melted into magma

• Its minerals must dissolve in water

• It must be exposed to high temperature and pressure

These rocks are often foliated, meaning they have layers.

• Sedimantary

• Sediment

• Metamorphic

• Igneous

As a result of cooling slowly, these rocks develop air pockets and are often very lightweight.

• Sedimentary

• Metamorpic

• Intrusive Igneous

• Extrusive Igneous

Formed by compacting & cementing of sediments

• Sedimentary

• Metamorphic

• Extrusive Igneous

• Intrusive Igneous

Has large crystals because of slow cooling

• sedimentary rock

• metamorphic rock

• intrusive igneous rock

• extrusive igneous rock

• Metamorphic Rock

• Sedimentary Rock

• Extrusive Rock
