In the jelly bean analogy, what represents the bonding agents?

• Salt and pepper

• Water and oil

• Sugar and spice

• Honey and corn starch

What causes a sedimentary rock to transform into a metamorphic rock?

• Cooling and solidification

• Melting and reforming

• Heat and pressure

• Compaction and cementation

What can you still see in a metamorphic rock that indicates its original form?

• Original structures

• Smooth surfaces

• Color changes

• Crystal sizes

How is an igneous rock formed from a metamorphic rock in the demonstration?

• Exposing to sunlight

• Applying pressure only

• Freezing the rock

• Melting in boiling water

What is magma?

• A type of sediment

• A metamorphic rock

• A mineral deposit

• Melted rock material

Which statement is true about the rock cycle?

• Metamorphic rocks do not change

• Any rock can transform into another type

• Only sedimentary rocks can transform

• It has a definite beginning and end
