Great value specimens for use in the classroom, included are various rocks that have been formed under the Earth's crust. They are called metamorphic as the immense heat and pressure down there causes igneous and sedimentary rock to morph into new rocks! They physically transform, but did you know that they also chemically transform?! Insider tip... Gneiss is pronounce 'nice'!
