things that are more dense sink while things that are less dense float
this is the concept that explains why some objects float on water while others sink. it all deals with density.
Some materials sink in water because they are more dense than the water. Others float because they are less dense than water.
They all float (on the mantle), some just float lower than others. The main reason is what they're made of; all plates have a high percentage of silica in them, but those with more aluminium than magnesium (continental plates) float higher than those with more magnesium (ocean floor plates) because they're less dense.
Density : if the weight per "cubic foot" is less than water it floats, if more it sinks.
Some olives float while others sink is due to the amount of brine they take on during the curing process.

On some liquids it will float, on others it will not.

Fish grow with age. Some only grow to the size of the tank while others grow to a maximum size no mater the size of their environment.
Because some objects are heaver than others.
