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 the magma is very important for solidificatoin temperature. When it starts to cool, crystals of minerals begin to grow. If it has a low silica content - which means high melting point - the magma will solidify at high temeratures. If it has a high silica content - which means low melting point - it will solidify at lower temperatures.
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.
· It is determined by the primary factors of the magma's Temperature, its Composition, and the amount of Dissolved Gases it contains.

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.
Intrusive rocks are formed when molten magma cools and solidifies beneath the Earth's surface. Factors that contribute to their formation include the composition of the magma, the depth at which it solidifies, and the rate at which it cools.
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.
1. a decrease in pressure, which lowers the melting temperatures of materials; this occur at mid-ocean ridges. 2. an increase in pressure, which causes materials in the asthenosphere to melt; this often occurs at a hot spot. 3. an increase in the amount of water in the asthenosphere, which lowers the melting temperatures of materials; this often occurs at subduction boundaries.
