What is a major contributor to suspended particles in the water?

Water motion is a major contributor to suspended particles in the water because it can stir up sediments and debris from the bottom of water bodies, making them more likely to be suspended within the water column. This stirring action can be caused by natural phenomena such as waves, currents, and tides. When water is in motion, it can dislodge particles from the substrate, also contributing to the overall turbidity of the water.

While tide changes can influence water movement and consequently affect sediment distribution, the primary action that increases suspended particles is the dynamic nature of water itself. Temperature fluctuations can affect water density and aquatic life but are not directly responsible for introducing suspended particles. Human activity can certainly contribute to increased sedimentation and the introduction of pollutants, but the question specifically addresses the physical aspect of water motion as the key factor in the suspension of particles.
