1. Crystallization:
* This is the primary transition magma undergoes as it cools.
* As magma cools, minerals start to solidify (crystallize) in a specific order based on their melting points.
* This process can lead to the formation of igneous rocks like granite, basalt, or gabbro depending on the specific minerals present and the cooling rate.
2. Differentiation:
* This refers to the process where the chemical composition of magma changes as it cools and crystallizes.
* Early-forming crystals, often denser, may sink to the bottom of the magma chamber, leaving the remaining magma enriched in different elements.
* This process can lead to the formation of different rock types from the same magma source.
Important Note: While these are the most significant transitions, magma can also undergo other changes underground like:
* Assimilation: Absorbing surrounding rock material into the magma, changing its composition.
* Mixing: Combining with other magma bodies, creating a new, mixed magma.
