Rocks formed when heat or pressure is added

WebIgneous rocks start as molten minerals formed deep in the earth under intense heat and pressure. 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.
