Why do particles carried by a river settle to the bottom as the river enters the ocean?

• The density of the ocean water is greater than the density of the river water.

• The kinetic energy of the particles increases as the particles enter the ocean.

• The velocity of the river water decreases as it enters the ocean.

• The large particles have a greater surface area than the small particles.

Small spheres that are identical in shape and size are composed of one of four different kinds of substances: A, B, C, or D. The spheres are mixed together and poured into a clear plastic tube filled with water. Which property of the spheres caused them to settle in the tube as shown in the diagram?

• their shape

• their size

• their density

• their hardness
