The metamorphic rocks are the rocks formed by the metamorphosis of the sedimentary and the igneous rocks due to presnece of high pressure and heat. These rocks can be either foliated or non foliated.
The foliated forms of the rocks show the realignment of the minerals due to high pressure and temperature. Due to the realignment, the different minerals represent a specific line and the direction of the pressure. The direction of the pressure is perpendicular to the mineral alignments.
Sophie is wrong because although dolphins and sharks can technically be said to be similar, it resulted from convergent evolution, which has nothing to do with common ancestry and rather to do with similar environments for their homes.
