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
No, obsidian is a type of volcanic glass that is denser than water, so it will sink when placed in water.
The lightest rock in the world is pumice. Pumice is a type of volcanic rock that is formed when lava with high water and gas content is rapidly cooled. It is so light that it can float 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 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.
In general, pumice will float. There is enough trapped air in pumice that it is buoyant.
Virtually all types of rock will sink in water. The only rock that can float on water is pumice.
Pumice.
There are only one type of rock that can float on water. And that is Pumice stone. According to more than millions of people's answers, that is the one.
Some types of pumice have enough air inside to float.
You can determine if a rock can float by comparing its density to the density of water. If the rock is denser than water, it will sink. If the rock is less dense than water, it will float. This can be tested by placing the rock in a container filled with water and observing its behavior.
Pumice is a type of volcanic rock that is known to float on water due to its porous nature.
Scoria is a type of volcanic rock that is typically denser than water, so it will sink in water.
Pumice is the lightest type of rock. It is formed from lava that is full of gas, which creates a frothy texture that allows it to float on water.
That is a type of rock called pumice.
No, obsidian is a type of volcanic glass that is denser than water, so it will sink when placed in water.
no
No, loadstone cannot float as it is a type of magnetic rock composed primarily of magnetite, which is heavy and dense. When placed in water, loadstone will sink due to its weight.
