Which of the following is common during crystallization of a magma?
A) felsic minerals crystallize first
B) mafic minerals are light and float in most magma chambers
C) felsic crystals are heavy and sink in most magma chambers
D) all crystals form at about the same time
E) none of these

Question

Quizplus · Accepted Answer

Crystallization of magma follows a specific sequence known as Bowen's reaction series, where mafic (magnesium and iron-rich) minerals typically crystallize first at higher temperatures, and felsic (silica-rich) minerals crystallize later at lower temperatures. This process does not occur uniformly (all at the same time), and the density of the crystals can vary, affecting their position in the magma chamber, but not strictly in the ways described in options B and C.
