Want this question answered?
The extrusive volcanic rock pumice can float on water. Other extrusive volcanic rocks are not so lucky.
If there is liquid in volcanic rocks, it would most likely be water.
Very porous rocks such as pumice can be very light and have the potential to float on water. Pumice is a volcanic rock.
Pumice can float in water. It is made from volcanic lava and has gases trapped in it, which makes it float.
Pumice, a volcanic stone with tiny air bubbles, is the only stone that floats in water.Pumice.Pumice, a volcanic porous stone, is lighter than water of equal volume because of all of the air bubbles in it, so it floats.
Pumice.
if it is pummice (volcanic rock) yes.
Pumice, a volcanic rock that is like a silicate version of Styrofoam, will float on water, if it is of high enough air content (some pumice is, some is not). Pumice rock is ground up and added to cleansers and some soaps (Lava) as a scrubbing agent.
rocks, metals ect.
Floating rocks: pumice. Non-floating rocks: all but pumice. Pumice can float on water because its density is so low, due to trapped bubbles of air which formed during its solidification from lava.
Geothermal Water
Because rocks are more dense than water
