Formation of Magmo Illustrated by: Ellissa Christie Kaye L. Murillo The magma rises and collects in chambers within the crust. As magma fills the chamber, pressure grows until the pressure gets high enough. Oceanic plates sink into the mantle below. As the oceanic plate sinks, When the pressure gets high enough, the magma can break through the crust and spew out in a volcanic eruption. The fluid flows up into the mantle rock above and changes its chemistry, causing it to melt and formation of magma. A denser oceanic plate collides with a continental plate.​
