What are two major differences between the appearance granite and basalt?
Granite is lighter and made up of feldspar and quartz, but basalt is darker and contains fine-grained minerals like magnesium and iron.
Basalt has a deeper color and contains fine-grained minerals like iron and magnesium. Just because of this characteristic, basalt rocks might also be referred to as mafic rocks. The meaning of the word "mafic rocks" will be clear to anyone who is familiar with the symbols for the elements magnesium (Mg) and iron (Fe).
Granite has a coarse-grained texture and a lighter color. These rocks are underneath, and the only time humans can see them is when deep erosion occurs. Granite is classified as a felsic rock since it mostly comprises feldspar and quartz, which gives it a distinct composition. Given the makeup of these rocks, granite has an acidic tendency. It is found above the sea and makes up a large portion of the continental crust.
