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.
When Magma solidifies within the earth, it cools down very slowly because the rock surrounding the magma are also hot.
· 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.

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.

Crystal settling is when the denser minerals and the remaining melt solidifies. The change in magma composition due to melting of surrounding country rock is called assimilation.
magma
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.
When magma solidifies, it becomes igneous rock.
