What Role Do Water And Other Volatiles Play In The Formation Of Magma??

What role do water and other volatiles play in the formation of magma? Water and other volatiles lower the melting temperature of magmas. Therefore, rocks will melt more readily with less pressure. … This process destroys the old crust, which melts and generates magma beneath the surface.

How does volatiles affect magma formation?

Volatiles increase rates of crystal growth, diffusion, and reaction and, in general, help to attain equilibrium. The release of volatiles from magmas can result in powerful disruptive phenomena such as volcanic explosions with their attendant propulsion of solid and liquid matter and disruption of surface features.
