Igneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the molten rock solidifies.Intrusive Igneous Rocks:Intrusive, or plutonic, igneous

He found that as a basaltic melt slowly cooled, minerals formed crystals in a definite order
