• magma/lava cooling
• precipitation

How are igneous rocks formed?

• magma/lava cooling
• heat and pressure
• compacting and cementing
• precipitation

How are sedimentary rocks formed?

• compacting and cementing
• magma/lava cooling
• heat and pressure

• transparent

Often times the surfaces of metamorphic rocks are foliated, which means that their surface has these?

• stripes or ribbons
• large crystals
• dead organisms
• holes

What is the difference between magma and lava?

• magma is below the surface, lava is above the surface
• lava is below the surface, magma is above the surface
• magma has is made of iron, lava is made of nickel
• there is no difference

What is intrusive igneous rock?

• igneous rock with large crystals 
• igneous rock with small, fine crystals

What is extrusive igneous rock?
