Rocks Rock

A rock deep within the Earth experiences extreme temperature and pressure. After a long period of time it becomes which rock?

• Magma

• Igneous

• Metamorphic

• Sedimentary

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

Rocks and sediment change as they move through the rock cycle. Which change involves turning into melting?

• Lava to rock

• magma to lava

• rock to magma

• rock to sediment

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

A geologist is studying three layers of sedimentary rock in an area. The layers have not shifted from their original positions. The geologist records the relative ages of the rocks. What did the geologist use to determine the relative ages of the rocks?

• Radioactive dating

• Mineral content

• Absolute dating

• The Law of Superposition

• 2, 1, 4, 3

• 3, 2, 1, 4

• 4, 3, 2, 1

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

Models help us study things that are too big, too small or too dangerous. Which of these is NOT a model?

• A diagram of the rock cycle

• A list of materials for Starburst Lab

• A Starburst sedimentary rock

• Tinfoil on a hot plate melting Starburst

Models serve many purposes. Which is NOT a purpose of a model?

• to perform a task

• to observe something that is very large

• to watch something change over time and speed it up

• to observe something very dangerous
