WebMetamorphism - what is it? Metamorphism means to change form. In the geologist's sense it refers to changes in rocks (protoliths) in the solid state (i.e. not by melting the rock wholesale). One can view metamorphism as similar to cooking. Ingredients are mixed and placed at a different temperature (and/or pressure) and changes occur.
