Magma consists of molten rocks and metals. The composition can vary based on presence of water, metals with different melting points, and such.
The composition of magma affects its chemical composition and mineral content, which in turn influences its melting and solidification temperatures. Magma with higher silica content tends to solidify at lower temperatures, producing rocks like granite. Magma with lower silica content solidifies at higher temperatures, forming rocks like basalt.
Volume does not directly affect the formation of magma. Temperature, pressure, and mineral composition are the key factors that influence magma formation.
The composition of magma changes as it rises through the crust due to various processes such as assimilation, crystallization, and mixing. As magma ascends, it can incorporate surrounding rock material which influences its composition. Additionally, as magma cools and solidifies, certain minerals crystallize out of the melt, altering its chemical makeup.

When fluids such as water combine with rock, the composition of the rock changes, which lowers the melting point of the rock enough to melt it.

When magma cools and solidifies, it forms igneous rocks such as granite, basalt, or obsidian. The specific type of rock that forms depends on variables such as the composition of the magma, cooling rate, and environment in which it solidifies.
Magma cools and solidifies to form igneous rocks such as granite, basalt, and obsidian depending on the cooling rate and mineral composition.
The composition of the magma effects the temperature it will cool and solidify at. In general most magma solidify at about 1,200 degrees Fahrenheit.
The factors that affect the formation of magma include temperature, pressure, composition of the rock, and presence of volatiles (such as water and carbon dioxide). Changes in these factors can lead to the melting of rock and the formation of magma beneath the Earth's surface.
The factors that determine how violent an eruption will be include the composition of the magma (silica content), the amount of gas dissolved in the magma, and the presence of water or other volatiles. The type of volcano (e.g. stratovolcano, shield volcano) and the location of the eruption can also affect its violence.
