Rocks float when their density is lower than that of the surrounding medium. E.g. in water, pumice floats; in an alkaline magma, felspathoids might float; in a basaltic magma, plagioclase would float at pressures greater than about 5kbar (! feldspathoids and plagioclase aren't rocks, these are minerals).

What is a lightweight rock that floats?
Pumice is a lightweight volcanic rock that floats on water due to its high porosity.
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 a piece of ice that breaks off a glacier and floats away called?
An ice that breaks off a glacier and floats away is called an iceberg.
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 is a light porous volcanic rock called?
Pumice is a light, porous volcanic rock that is commonly used in beauty and skincare products for exfoliation. It forms when volcanic lava rapidly cools and traps gases, creating its characteristic porous texture.
What do you called an igneous rock that floats on water due to the presence of many gas bubble holes.?
Pumice is such a rock.

What is the name of a very porous igneous rock so light that it floats?
pumiceThe type of igneous rock that floats is called Pumice. It isn't lighter than other rocks, just less dense because it has lots of very small air bubbles trapped in it. You can see these if you look at the exterior of the rock.
The extrusive igneous rock that floats in water?
Pumice
What is the area that is made of huge slabs of rock that floats on the mantle?
Crust
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 the name of a very porous igneous rock that is so light that floats?
pumice
Is the mantle a solid or something else?
The mantle layer of the planet Earth is made of hot liquid rock (called magma). The crust, upon which we live and type, floats on the mantle.
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.
