Which type of stone is lighter than water?
pumice or any other low density rock
How can there be a rock that can float?
Floating (on water) happens when the item place in the water is less dense than the water. The density of the rock called "pumice" is less than that of water so pumice floats. Pumice is a volcanic rock made form a lava "foam" it is solidified rock froth and therefore is very light.
Are pumice stones and lava rock comparable?
Not all lava rock is pumice. Lava rock is a term used synonymously with pumice by some material suppliers. Actually though, any rock formed from cooling lava would be considered a 'lava' rock and would include rocks like pumice, obsidian, and basalt. Only lava has a density less than that of water, allowing it to float.
Does basalt float in water?
NO but pumice does because of little gas bubbles within it because of the volcano
Can metamorphic rocks float?
The extrusive volcanic rock pumice can float on water. Other extrusive volcanic rocks are not so lucky.
What type of rock will float on water?
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
Name an extrusive rock with a very low density?
Pumice is an extrusive igneous rock with a density less than that of water.
Is a pumice rock a rock or a mineral?
Pumice is an extrusive igneous rock, not a mineral.
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.
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.

Is there such a thing as a floating rock?
Yes. It's called pumice, an extrusive felsic igneous rock with a density less than that of water.
Does pumice floats in water?
Porous lava rock is called pumice. If placed in water, it would float as it possesses a density that is less than water.
Does basalt float in water?
NO but pumice does because of little gas bubbles within it because of the volcano
