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, 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.
