Porous lava rock is called pumice. If placed in water, it would float as it possesses a density that is less than water.

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.
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.
What is the name of the igneous rock that is light enough to float?
Pumice, an extrusive igneous rock. Pumice is very porous and therefore allows air to get trapped when it is in water. Pumice stones are formed when lava cools quickly, they are usually white in colour and have a heavily pitted surface.
Will pumice float or sink in water?
In general, pumice will float. There is enough trapped air in pumice that it is buoyant.

The extrusive igneous rock that floats in water?
Pumice
Which stone floats in water?
Pumice floats on water. It is because it is made out of lava which had bubbles left inside it. The bubbles has air trapped in it. These bubbles allow pumice to float on water.
What stone float in water?
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.
Why pumice is the only rock that floats?
it is lighter than the weight of water
Which stone never fell down in water but remain on the top of water?
Pumice stone floats on water.
What is a light porous volcanic rock called?
Pumice. It floats on water due to its vesicular structure.
What is the difference of a pumice and a slate?
Pumice is a porous rock and slat is not. Pumice floats in water because of the air pockets in the rock. Slate is a layer of rock that is tightly packed, or is very "dense".
Why does pumice float in water using buoyancy and density?
Although pumice is volcanic stone, it has air pockets inside making it less dense than water, so it floats.
Does a real diamond sink or float in water?
A diamond sinks in water. There is only one stone that floats, pumice.
What is a lightweight rock that floats?
Pumice
How can there be a rock that floats and what are three ways that this rock can be formed?
Very porous rocks such as pumice can be very light and have the potential to float on water. Pumice is a volcanic rock.
