Yes, minerals can crystalize when magma melts.
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.
1) Ocean water seeps down through cracks in the crust. 2) Water comes in contact with magma that heats it to a very high temperature. 3) The heated water then dissolves minerals from the crust and rushes upward. 4)The solution billows out of chimneys. When the solution hits the sea, minerals crystallize on the ocean floor.
Partial melting occurs in rocks because the different minerals that compose rocks have different melting points. For example, felsic minerals (e.g. quartz and feldspar) melt at around 700 degrees Celsius while mafic minerals (e.g. pyroxene and olivine) melt at around 1200 degrees Celsius. Therefore, felsic minerals will melt first leaving the mafic minerals solid.Fractional crystallization occurs when minerals from a magma cool and crystallize out of the magma. The first crystals to melt in partial melting will be the first minerals to crystallize out when the magma begins to cool. Therefore, mafic minerals will crystallize first, followed by felsic minerals.Both partial melting and fractional crystallisation tend to produce a more felsic magma than their source rocks.The difference is simply that they are the reverse of one another, heat it up, cool it down. Things that melt first solidify last and separate from one another.
metamorphic rock melts into magma and volcano erupts. lava hardens and cools
its helpful because it melts the rock and if it wasn't it for melting, then the rocks would be WAY harder and rougher than they normally are.Hope it helped! :)
No. Magma is already at least partially molten. Mineral crystallize when magma solidifies.
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.
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.

due to slow cooling of magma within the earth causes the minerals to crystallize.
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.
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.
when magma cools fast you get smaller crystals when it cools slow you get large crystals its very simple
