Igneous Rocks. Goals To understand what your “granite” counter top is really made out of and to use that knowledge to make plate tectonic interpretations.

Mafic Intermediate Felsic - The mantle is made up of peridotite (ultramafic composition) - So why/how do we end up with so many different magma.
