Geologists classify metamorphic rocks by the arrangements of the grains that make up the rocks.
by carol and size
they look through a microscope
Geologists classify rocks by looking at their chemical and mineralogical composition then at the the size and shape of their component minerals then at any texture, pattern or grain that the rocks may display. They also classify them in relation to how they were formed.
Color and texture is one way to classify igneous rocks. Another way to do this is modal classification and normative classification.
yes,either felsic if light coloured or mafic if dark cloured.we classify rocks like that especially igneous rocks but COLOR IS NEVER USED TO IDENTIFY ANY ROCK.only classification.

That was how racism was born.
Sedimentary rocks are separated by lines of weakness called bedding planes. These planes represent the original horizontal layers in which the sediments were deposited, and they often serve as zones of weakness along which rocks may break or deform.
