Question

Quizplus · Accepted Answer

Pumice is a vesicular felsic rock that forms from the rapid cooling and solidification of lava that contains a high amount of gas or volatiles. The gas bubbles get trapped in the lava as it cools, forming the distinctive vesicles or pores within the rock. Pumice is typically light-colored and highly porous, with a low density that allows it to float on water. It is commonly used as an abrasive, as an additive in concrete, and as a soil conditioner.
