SUMMARY
Freshwater and saltwater remain largely unmixed due to differences in density and salinity. Saltwater is denser and has a higher salt concentration, which creates a distinct boundary between the two. This boundary allows for diffusion, the only mixing process, to occur slowly. Factors influencing the rate of mixing include salinity differences, layer thickness, and temperature, with mixing times ranging from minutes to years depending on specific conditions.
