The rock pumice often floats yet the density of the rock is greater than water.  Why does it float?
A) Pumice is a rock made of rhyolite glass that erupts into water, which traps water in voids and makes the material less dense than water.
B) Pumice is a pyroclastic rock comprised largely of open voids formed by gases released when the magma solidified as froth-like material.
C) Pumice is a pyroclastic rock derived from rhyolite glass, and rhyolite glass has a lower density than water.
D) Pumice is another name for dacite, a low-density rock that floats in water.
