Igneous Rocks form from volcanoes.
• Intrusive• Cooled trapped
magma inside Earth• Cools slowly• Has crystals
• Extrusive• Cooled lava
outside of Earth• Cools quickly• Few, if any
crystals

Most igneous rocks are made of silicate materials.
• High silica composition makes a rock light colored. (Highlight – like a highlighter)
• Low silica composition makes a rock dark colored.
