❓ why
Why do some rivers have colored stripes or swirls near their mouths?
Quick Answer
Different currents and sediment sources can mix unevenly, creating visible bands, plumes, and swirls in the water.
The Full Story
Where a river enters a larger body of water, fresh water does not always mix instantly with saltwater or lake water. Differences in density, speed, and sediment load can create striking patterns. Muddy river water may flow as a plume while clearer water stays beside it. Wind, tides, and eddies can twist these patterns into swirls or stripes. Satellite images often reveal these boundaries clearly at large river mouths.
