Pumice the only common rock that floats in water.
But flotation is a technique often used in the processing of rocks for lab study.
For this, very dense fluids are used such as polytungstates, or some heavy chlorinated or brominated liquids. Some of these have a relative density of 3.

Why pumice is the only rock that floats?
it is lighter than the weight of water
What is a lightweight rock that floats?
Pumice
Sample of trivia for physics?
The only rock that floats in water is pumiceAll moving objects are merely wave packets of extremely high frequency.
What is the name of a very porous igneous rock that is so light that it floats on water?
Pumice is basically lava froth, an extrusive rock frozen as its dissolved gases come out of solution. It looks solid but often floats on water.
What is the only solid that floats in its liquid?
Water
Where do you find a rock that floats?
The on rock that floats is a pumice. It is a kind of volcanic glass. The reason it floats is because it has big pours all over it. I'm only in 8th grade and I still know the answer.

Name the Only rock that flows?
If you mean the only rock that floats, than it would be pumice, which is often used to remove hard skin.
What rock floats on water?
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.
What rocks float?
Vessicular Rocks. Eg Scoria and Pumice.
What is a lightweight rock that floats?
Pumice
The extrusive igneous rock that floats in water?
Pumice
Pumice is a volcanic rock that floats Its density is?
With out knowing further knowledge about the rock it is unable to determine the exact density. However, since the rock floats, presumably in water, the density must be less then 1.00g/L.

Does a lodestone float?
No. If a rock floats it is most likely pumice.
Why would one rock float while one sinks?
The rock that sinks has a higher density than the rock that floats. (The only rock that floats is pumice.) More specifically, for a rock to float it must have a lower density than the fluid it is placed in. This will mean that a given volume of the material will have a smaller mass (and hence weight) than the fluid it displaces. As such the material will have positive bouyancy and will tend to float on top of the more dense material.
What is the area that is made of huge slabs of rock that floats on the mantle?
Crust
