i can give you more than two Galena, Gold, Copper, Sulfur, Pyrite
Magma rises when it is being pushed or heated from below.
Magma is molten rock, as the magma cools the minerals crystallize out of it, the slower it cools, the larger the crystals.
Yes; through the process know as fractional crystallization, which changes the composition of the magma, therefore changing the minerals that eventually crystallize from it. Fractional crystallization occurs largely from the varying temperatures at which minerals crystallize.
The hot magma heats the ocean water that seeps underground. The heated water dissolves minerals. When the solution billows out of vents called "chimneys" the minerals crystallize in the cold sea water. I hope that answers your question ^^
Bowen's Reaction scale lists the order in which minerals crystallize. Olivine or ultramafic minerals are the first to crystallize. They do so at high temperatures, whereas quartz is the last to crystallize, and at low temperatures. Through Bowen's many studies, he found that the order of magma from high to low temperature is ultramafic, mafic, intermediate, and felsic. Plagioclase feldspar follows the crystallization of olivine.

Yes, minerals can crystalize when magma melts.
Magma is molten rock, as the magma cools the minerals crystallize out of it, the slower it cools, the larger the crystals.
The Bowen's Reaction Series lists the order of crystallization of minerals from high temperature to low temperature environments, starting with olivine and ending with quartz. See the link below.
No. Magma is already at least partially molten. Mineral crystallize when magma solidifies.
Minerals with higher melting points will crystallize.
The process is cooling. When magma cools slowly, large well-define crystals form.
Olivine is the first mineral to crystallize as the mineral first to crystallize is the last to melt.
As a magma crystallizes it undergoes fractional crystallization in which mafic minerals crystallize first and felsic minerals crystallize last. Therefore, as fractional crystallization occurs the magma becomes increasingly less mafic and increasingly more felsic. The viscosity also increases as a magma becomes more felsic.
A geyser may form from ground water heated by magma.
The temperature of the magma will affect its viscosity depending on its chemistry. Some minerals crystallize at higher temperatures than others, meaning that portions of the magma may have already solidified. At lower temperatures, the majority of the constituent minerals will have crystallized and solidified, leaving the magma highly viscous.
