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

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

The process that breaks down rocks and other materials on Earth's surface is called

• weathering

• erosion

• soil conservation

• decomposition

What is mechanical weathering?

• process through which rocks are physically broken into smaller pieces

• Rocks are broken down through chemical changes.

• Rocks are worn away from acid in plant roots.

• Rocks broken down by machinery.

What is erosion?

• The process by which water, ice or gravity move fragments or rock and soil.

• The process by which water, ice, wind or gravity deposit rock sediments and soil in a new place.

• The breaking down of Earth's crust into smaller and smaller pieces.

__________ weathering is a type of weathering that changes a rock's composition or color.

• chemical

• physical

• mechanical
