• How does crystal size compare in extrusive vs. intrusive rock? Explain the cause of this difference.

OpenStudy (princess_shadow_sob):

@xMissAlyCatx

OpenStudy (xmissalycatx):

the major visible difference between the two are crystal size, intrusive rocks have a larger crystal/grain texture due to the slow cooling of magma below the earth surface which encourages the growth of larger crystals, while extrusive rocks, because of the rapid cooling at/above the earth's surface does the opposite.

i agree with @xMissAlyCatx in the first answer that she said and if i may add on to it i would say that when the intrusive rocks are cooled they will not only have larger but more in depth smoothness to the crystals while the extrusive rock will have jagged edges that may end up cutting anything that might step on it or pick it up
