Less dense materials rise to the top.
 A True B False C Either A or B D None of the above
Explanation:

Detailed explanation-1: -If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float. Density is a characteristic property of a substance and doesnâ€™t depend on the amount of substance.

Detailed explanation-2: -The most dense liquids will be found on the bottom, the least dense liquid is on the top. See Table below. Any objects placed in the liquids will seek their own level depending upon the density. If an object has a density that is intermediate in value, the object will float between two layers.

Detailed explanation-3: -If you weigh equal amounts or volumes of two different liquids, the liquid that weighs more is more dense. If a liquid that is less dense than water is gently added to the surface of the water, it will float on the water. If a liquid that is more dense than water is added to the surface of the water, it will sink.

Detailed explanation-4: -The denser materials make the pressure below greater. then the greater pressure acts on the bottom of the less dense material, the upwards force from this pressure is greater than the downwards force of gravity. So the net force is upwards and so the less dense materials rise.
