1. Origin of granite Misconception
Correction: magma forms in the lower lithosphere as water reduces the melting point of the rocks above the subducting slab; granite crystallizes slowly from melted continental material and maybe by fractional crystallization of mafic to intermediate magmas.
Misconception
ELIZABETH I: [Looking at a granite] Maybe if the magma was still inside of the Earth and it didn’t come up, parts of that magma could become granite. Basalt picks up crystals from a rock layer as it rises to the surface. Under pressure beneath the surface, the crystals combine to get bigger and form granite.
