Igneous Rocks

• Made of cooled molten material– Magma: molten

material located INSIDE the earth

– Lava: molten material located OUTSIDE the earth

Igneous Rock Types

• Extrusive– Formed

OUTSIDE the earth

– Mineral grains/crystals are SMALL•Molten

material cools quickly

• Intrusive– Formed INSIDE

the earth– Mineral

grains/crystals are LARGE•Molten

material cools slowly

Metamorphic Rocks

• Created inside the earth through HEAT and pressure

• Mineral grains are flat and aligned

• All rocks (sedimentary, igneous and/or metamorphic) can become metamorphic rocks under the right conditions
