Question

caleb drops a rock in a puddle of water and it sinks to the bottom. what can be said about the density of the rock versus the water? options: water has greater density, the rock has greater volume, the rock has greater density, their densities are equal

Explanation:

An object sinks in a fluid when its density is greater than the fluid's density. Since the rock sinks in water, the rock's density must be greater than water's density. The option "water has greater density" is incorrect as that would make the rock float. "The rock has greater volume" is not related to sinking (density, not volume alone, determines sinking/floating). "Their densities are equal" would mean the rock is suspended, not sinking. So the correct option is the one stating the rock has greater density.

Answer:

the rock has greater density
