What is a lightweight rock that floats?
Pumice is a lightweight volcanic rock that floats on water due to its high porosity.
What is the only rock floats?
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 floats while a rock of similar size will sink in the same tank of water?
When pumice is formed - it traps minute amounts of gas in bubbles within the rock itself. This makes it buoyant.
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.
What is an igneous rock that is gray and floats in water?
Pumice is a grey volcanic rock so full of gas bubbles that it is able to float on 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 is a lightweight rock that floats?
Pumice is a lightweight volcanic rock that floats on water due to its high porosity.
The extrusive igneous rock that floats in water?
Pumice
Where do you find a rock that floats?

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 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".
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.
What is the name of The rock which do not sink in water?
pumice stone
What rocks float?
Pumice is a type of rock that can float on water due to its high porosity and low density. It is formed from volcanic eruptions and is commonly found near volcanic regions.
What is the name of a very porous igneous rock that is so light that floats?
pumice
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.
What is the only rock floats?
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.
