Science Rocks, types of rocks

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

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

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

What type of rock would you most likely find a fossil inside of?

• sedimentary
• igneous
• metamorphic
• diamond

What is the relationship between a rock and a mineral?

• Rocks are made up of minerals.

• Minerals are made up of rocks.

• Rocks are on the Earth's surface. Minerals are found underground.

• Rocks and minerals are different names for the same thing.

This rock formed when lava cooled very quickly on Earth's surface. What specific type of rock is it?

• Extrusive Igneous Rock
• Intrusive Igneous Rock
• Non-Foliated Metamorphic Rock
• Biochemical Sedimentary Rock

When you watch a volcano erupt molten rock, you are seeing _____

• Lava
