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

• Velocity of the river water decreases as it enters the ocean
• Kinetic energy of the particles increases as the particles enter the ocean
• Density of the ocean water is greater than the density of the river water
• Large particles have a greater surface area than the small particles
