Pumice definition of Pumice and synonyms of Pumice

Most pumice is light enough that it floats on water The unusual y configuration of pumice happens because of simultaneous rapid cooling and rapid depressurization The depressurization creates bubbles by lowering the solubility of gases (including water and CO 2 ) that are dissolved in the lava causing the gases to rapidly exsolve (like the bubbles of CO 2 that appear when a carbonated
