Pumice is full of holes called vesicles formed from gasses escaping the molten rock. The holes greatly reduce its density.
First it is pumice, and it floats because when it forms from cooling lava, little gaseous bubble get trapped inside that are lighter than air.
In general, pumice will float. There is enough trapped air in pumice that it is buoyant.
Pumice rocks have been known to float across oceans.
Any with a density less than the fluid into which it is placed. Pumice is a volcanic rock that will sometimes float on water.pumice
Vessicular Rocks. Eg Scoria and Pumice.
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.
In general, pumice will float. There is enough trapped air in pumice that it is buoyant.

Pumice is able to float.
It can float.
The pumice is not very dense, if the mass of the volume of water displacement is greater than the mass of the rock it will float
scoria will sink but pumice will float.
No. Only pumice (volcanic) stone can float.
Pumice.
it has holes in it and has kelfrigis
No, but pumice can.
