If a rock has many airbubbles in it, like volcanic rock has, it is possible for a rock to float.
If a rock feels heavy in your hand, it propably will not float.
A rock floats in water due to buoyancy, which is the upward force exerted by the water on the rock. If the rock is less dense than the water, it will displace an amount of water equal to its weight, causing it to float. Additionally, surface tension can also play a role in helping small rocks or pebbles float on the surface of water.
A rock sinks in water because its density is greater than that of water. The weight of the rock is heavier than the water it displaces, causing it to sink rather than float.
A rock could float if its density is less than that of water, as is the rock pumice, or if it is shaped in a manner that would displace an amount of water to sufficiently cause it to float when carefully placed in water.
The extrusive volcanic rock pumice can float on water. Other extrusive volcanic rocks are not so lucky.
No, obsidian rock does not float as it is a dense and heavy igneous rock formed from cooled lava. Its high density causes it to sink in water.
Virtually all types of rock will sink in water. The only rock that can float on water is pumice.

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

It will float. Its a rock. It actually depends on how much water you have, if you you tried float it in the ocean, it would obviously sink. But if you tried to float it on a gladd or bowl or water, it would float,
Pumice can float in water. It is made from volcanic lava and has gases trapped in it, which makes it float.
No. Molten rock is heavier than water.
