Modern Science has discovered that in the places where two different seas meet, there is a barrier between them. This barrier divides the two seas so that each sea has its own temperature, salinity, and density. For example, Mediterranean sea water is warm, saline, and less dense, compared to Atlantic ocean water.
When Mediterranean sea water enters the Atlantic over the Gibraltar sill, it moves several hundred kilometers into the Atlantic at a depth of about 1000 meters with its own warm, saline, and less dense characteristics. The Mediterranean water stabilizes at this depth (see figure 13).
Although there are large waves, strong currents, and tides in these seas, they do not mix or transgress this barrier.
The Holy Qur’an mentioned that there is a barrier between two
seas that meet and that they do not transgress. Allah (S.W.T) has said:
He has set free the two seas meeting together.
There is a barrier between them.
They do not transgress. (Qur’an, 55:19-20)
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. Allah (S.W.T) has said in the Qur’an:
He is the one who has set free the 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)
One may ask, why did the Qur’an mention the partition when speaking about the divider between fresh and salt water, but did not mention it when speaking about the divider between the two seas?
Modern science has discovered that in estuaries, where fresh (sweet) and salt water meet, the situation is somewhat different from what is found in places where two seas meet. It has been discovered that what distinguishes fresh water from salt water in estuaries is a “pycnocline zone with a marked density discontinuity separating the two layers.” This partition (zone of separation) has a different salinity from the fresh water and from the salt water (see figure 14).
This information has been discovered only recently, using advanced equipment to measure temperature, salinity, density,oxygen dissolubility, etc which was not possible 1400 years ago. It must be from mighty creator.
The human eye cannot see the difference
between the two seas that meet, rather the two seas appear to us as
one homogeneous sea. Likewise, the human eye cannot see the
division of water in estuaries into the three kinds: fresh water, salt
water, and the partition (zone of separation).
Say, “I only exhort you to do ONE thing: That you rise for the sake of Allah in pairs or singly and THINK & REFLECT!…” [34:46]
Say, “Are the ones who are blind in respect of the mind equal to those who are endowed with mental perception and understanding? Will you not then THINK & REFLECT?” [6:50]
We explain in detail Al-Ayaat (verses) for the people who THINK & REFLECT [10:24]
Respected readers, are there any more doubts?……………………..Think again!
Have a nice day.
