WebIgneous 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. WebMagmatic Differentiation. The defining characteristic of igneous rocks is that at one time they were molten and part of magmas or lavas. A magma is a body of molten rock that occurs below the surface of the earth.
