How do Sweet Sea Water Occurs?

Question

How do Sweet Sea Water Occurs?

Answer 1

Fresh water has a different density than the high saline seawater so it floats on top before mixing. If there has been a heavy rainfall so fresh water is added in a large volume it can cover the seawater for a distance and can even spread along the coast a distance depending on wave action and rate of evaporation.

Pure cold water flowing over seawater 's higher density actually has a boundary that slows mixing
