Pumice is an extrusive igneous rock that has a lower density than an equal volume of water. Pumice forms from an airborne, rapidly cooled frothy magma, full of tiny gas pockets, making it extremely light in weight.

What is a light porous volcanic rock called?
Pumice. It floats on water due to its vesicular structure.
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.
Does basalt float in water?
NO but pumice does because of little gas bubbles within it because of the volcano
Does mud absorb water?
Mud does absorb water.
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.
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.
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.
Will pumice float or sink in water?
In general, pumice will float. There is enough trapped air in pumice that it is buoyant.
Which stone is not drown in the water?
Pumice
Stone which does not drowns in water?
Pumice, a volcanic stone, does not sink in water.There is one type of stone that won't SINK in water.....pumice.
Is it safe to clean water stains from glass with pumice?
anything abrasive, such as pumice, will cloud your glass
Which rock will brake if you freeze it in water schist pumice or sandstone?
Which Rock Will Brake If You Freeze It In Water Schist Pumice Or Sandstone? Answar: Sandstone
Which rock doesn't sink in water?
Pumice does not sink in water.
Which stone did not sink in the water?
Pumice stone does not sink in water
Why does scoria have a similar texture to pumice but does not float on water like pumice?
Scoria has thicker vesicle walls than pumice does. This means it has a lower proportion of open space in it, making it less dense than water.
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 type of rock can float on water?
Pumice.
