A rock has more density than water. That's why it drops. Its easier to lift it in water because water's density is greater than that of air, so the net buoyancy of the rock, though still negative, is greater than it is in air.

How can you determined if a rock can float in water?
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.
Can you make a rock 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.
How it is possible for a rock to float in water?
if it is pummice (volcanic rock) yes.
Can metamorphic rocks float?
The extrusive volcanic rock pumice can float on water. Other extrusive volcanic rocks are not so lucky.
Which igneous rock has tiny air bubbles trapped inside which allow it to float in water?
Pumice has tiny air pockets to help it float in water.
What type of rock cannot float on water?
Virtually all types of rock will sink in water. The only rock that can float on water is pumice.

Will a obsidian rock float on water?
No it will not.
Does a shale rock float in water?
no
Can you lift an object with water?
Yes.Since water contains materials in water, diet soda will float.
What type of rock can float on water?
Pumice.

Does Anorthite sink or float in water?
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,
What rock can flow in water?
Pumice can float in water. It is made from volcanic lava and has gases trapped in it, which makes it float.
Can molten rock float on water?
No. Molten rock is heavier than water.
Can metamorphic rocks float?
The extrusive volcanic rock pumice can float on water. Other extrusive volcanic rocks are not so lucky.
