So my assignment was to read this article about this rock, and my mom said go ahead an write a paragraph about the rock so I did.
Gneiss is a crystalline rock that is not covered by a layer of sedimentary rocks, and it is most commonly found in the lower parts of the continental crust. Most of the mineral grains of the gneiss rocks are visible to the naked eye. Germans first started using the word “gneiss”. Gneiss is a rock type that is defined by its oriented texture.
