The mineral that crystallizes first from a cooling magma is the one with theGroup of answer choiceslowest solubility.highest melting point.highest solubility.lowest melting point.

Which of following correctly lists the order in which the listed minerals form in a cooling magma from the first to the last to form?Multiple Choicepyroxene, biotite mica, calcite, quartz, and potassium-rich feldsparolivine, pyroxene, amphibole, biotite mica, and quartzquartz, biotite mica, amphibole, pyroxene, and olivinequartz, potassium-rich feldspar, pyroxene, biotite mica, and calcite

Mineral growth in magmas at the surface with temperatures around 800 to 1,300°C occurs in the following wayMultiple ChoiceIron and magnesium will link up with aluminum and the silicon-oxygen tetrahedron as magma temperature decreases to sequentially form four distinct and discontinuous families of minerals—olivine, pyroxene, amphibole, and biotite mica.Calcium will combine with aluminum and the silicon-oxygen tetrahedron to begin forming the plagioclase feldspar family, a continuous and gradational series of minerals.Both of these are correct.None of these choices are correct.
