Volcanivity of molten rock in the mantle, caused by thermal convection currents, coupled with gravitational effects of changes on the earth’s surface erosiondepositioneven asteroid impact and patterns of post-glacial rebound golcanicity plate tectonic motion and ultimately volcanism. Magma trapped below ground in thin intrusions cools more slowly than exposed magma and produces rocks with medium-sized crystals.

As magma cools the chemicals in the crystals formed are effectively removed from the main mix of the magma by a process known as fractional crystallizationso the chemical content of the remaining magma evolves as golcanicity solidifies slowly.
