Vessicular Rocks. Eg Scoria and Pumice.
Pumice is the ONLY rock that floats.
Pumice rocks have been known to float across oceans.
It depends on the type of rock. A rock like sandstone would not sink if it is a small peice. Small rocks can float. That's when its called silt.
No. Shale sinks like almost all rocks.
Magma tends to rise towards Earth's surface primarily because rocks become less dense when they melt. The hotter the magma, the more the rocks are likely to "float," if you will.
Which rock? Any liquid that is dense enough will support a rock; the most common would likely be mercury, in which even iron floats.
Well rocks don't float because they are a solid with no air.
Pumice rocks have been known to float across oceans.
No rocks float, irrespective of color with the exception of pumice, a solidified lava froth.
No
the density
it has holes in it and has kelfrigis
asteroids

Pumice.
Because rocks are more dense than water
No they will sink or break apart
