Where the numerator represents the map distance which always equals 1 and the denominator represents the ground distance which has similar units as the numerator.
Light colored igneous rock is called felsic, it is high in quartz, muscovite mica, and orthoclase feldspar content. Dark colored igneous rock is called mafic, and contains a lesser amount of silica along with olivine, pyroxene, amphibole, biotite mica, and plagioclase feldspa
<span>Light coloured igneous rocks (felsic) tend to have greater silica and aluminum content and a lower iron and magnesium content than dark (mafic) rocks.</span>
