A rock, for one, although pumice will float. Any object whose desnsity is greater than water's will sink.
Not unless somebody is holding it down. If the rock weighs 10N and you just set it in the water, it'll sink until it displaces 10N of water, and at that point, it has no desire to sink any further.
This is ROCK so it will SINK
well maybe a rock,a Golf ball, and a marble. things that are heavy can sink
Pumice does not sink in water.
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.
Virtually all types of rock will sink in water. The only rock that can float on water is pumice.
pumice (a volcanic rock)
Sink. Like a rock. Faster than a rock. The density of water is ~1 g/cm3. Anything more dense than that will sink.

All kayaks will sink if filled with enough water. It changes how much is needed, though.
Gravity
yes, as long as it has a higher density that the water (or liquid it is sinking into)!

A rock always weighs something unless in free fall. If you are asking why that rock doesn't sink in mercury, its because rock density is 2-3 while mercury is 7.6. The object with higher density will sink. In the case of water, a rock is more dense than water(having a density of 1) and sinks in water.
A Rock would obviously sink in water and a egg would float in salt water Believe it or not bowling balls that are denser than water float!
