A rock sinks because it is not buoyant. Buoyancy is whether or not something floats in water. There are three levels of buoyancy; buoyant, neutrally buoyant, and not buoyant. When something is buoyant, that means it has a lower density than water, causing it to float. When something is neutrally buoyant, that means it has roughly the same density as water, causing it to float half way between the bottom and the surface. Finally, when something is not buoyant (like a rock), that means that it has a higher density than water, causing it to sink to the bottom.
What else can I help you with?
A rock will sink because it is heavier than..?
A rock will sink because it is more dense than the liquid into which it is placed.
Why does cooler rock sink?
Because thing that are denser sink. Therefore, cooler rock sinks because it is denser.
Does granite rock sink or float?
Granite rock is denser than water, so it will sink when placed in water.
Will a rock sink in water on the moon?
Yes. The weaker gravity on the moon does not change the fact that rock is denser than water. The rock will sink more slowly than it would on Earth, but it will still sink.
Can igneous rock sink?
Old, cool igneous rock sinks.
Why does oceanic rock always sink below continental rock?
subduction
Does the density of a rock cause it to sink or float in water?
Density describes mass per unit volume. Pretty much all rocks will sink unless there is air in it
What two currents did the Titanic sink on?
a rock
Which rock doesn't sink in water?
Pumice is a type of volcanic rock that is known to float on water due to its porous nature.
Does anorthite float or sink?
Anorthite has a specific gravity greater than 3, which means it is denser than water and will sink in it.
What is it called when rock layers sink?
It is called subsidence.
What rock or mineral makes a sink?
usually marble
