Editing Planetary differentiation (section)

===Thermal diffusion===
When material is unevenly heated, lighter material migrates toward hotter zones and heavier material migrates towards colder areas, which is known as [[thermophoresis]], thermomigration, or the [[Thermophoresis|Soret effect]]. This process can affect differentiation in [[magma chamber]]s. A deeper understanding of this process can be drawn back to a study done on the Hawaiian lava lakes. The drilling of these lakes led to the discovery of crystals formed within magma fronts. The magma containing concentrations of these large crystals or [[Phenocryst|phenocrysts]] demonstrated differentiation through the chemical melt of crystals.
