<h2>Answer:</h2><h3><em>Igneous — they form from the cooling of magma deep inside the earth. They often have large crystals (you can see them with the naked eye). </em></h3><h3><em>Metamorphic — they are formed through the change (metamorphosis) of igneous and sedimentary rocks. They can form both underground and at the surface.</em></h3><h3><em>Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into loose material in a source area.</em></h3>
