Modern science has recently discovered that in the places where two different seas meet, there is a barrier between them:He (Allah) has set free the two seas, meeting together, with a barrier between them they do not break through. (Qur'an, 55:19-20)
Due to the physical force called ‘surface tension,’ the waters of neighbouring seas do not mix. Caused by the difference in the density of their waters, surface tension prevents them from mingling with one another, just as if a thin wall were between them. It is interesting that, when there was little knowledge of physics, and of surface tension, or oceanography, this truth was revealed in the Qur'an. Although there are large waves and strong currents in the Mediterranean Sea and the Atlantic Ocean for example, their temperature, salinity, and densities do not change, because of the barrier that separates them.
But when the Qur’an speaks about the divider between fresh and salt water, it mentions the existence of ‘a forbidding partition’ with the barrier:
He (Allah) is the one who has set free two kinds of water, one sweet and palatable, and the other salty and bitter. And He has made between them a barrier, and a forbidding partition. (Qur’an, 25:53)
Modern science has discovered in estuaries where fresh (sweet) and salt water meet, the situation is somewhat different from the places where two seas meet. A pycnocline zone with a different salinity from both the fresh and salt water. This information was discovered recently with equipment to measure temperature, salinity, etc. The human eye cannot see this division.
