Fine grained and coarse grained igneous rocks @ 7:02 PM
To sec 1C, 1E, 1F and 1H, I apologise for making a mistake. granite is coarse grained and pumice is fine grained. Pumice is fine grained as it cools faster, so the crystals become small and do not have the effect of the heat to expland the crystals slowly.If you need more help to clarify this matter, please look for me. Thank you.
