The unusual foamy configuration of pumice happens because of simultaneous rapid cooling and rapid depressurization. The depressurization creates bubbles by lowering the solubility¬¨‚Ćof gases (including water¬¨‚Ćand CO2) that are dissolved in the lava, causing the gases to rapidly exsolve¬¨‚Ć(like the bubbles of CO2¬¨‚Ćthat appear when a carbonated drink is opened).
