The textures of igneous rocks, sedimentary rocks, and metamorphic rocks are all described with different terminology. That is, you cannot describe the texture of a sedimentary rock with the terms used to describe textures of igneous rocks. Bearing this in mind, please sort the terms below pertaining to rock textures into the three rock classes. lgneous rocks have textures that are either comprised of interlocking crystals, or textures that resulted from the cooling of hot liquid material. Sedimentary rocks have...
