Pumice is pyroclastic igneous rock that was almost completely liquid at the moment of effusion and was so rapidly cooled that there was no time for it to crystallize. When it solidified, the vapours dissolved in it were suddenly released, the whole mass swelling up into a froth that immediately consolidated
Explanation:
Over time, with intense heat and pressure, pumice stone will break down and crumble and scatter about, or become more compact, forming a new type of rock in the rock cycle.
