The quran didn't mention specific seas but he shows his power over things that with his power both seas with different charactristics and properties which are in full contact but never mixed as to be just one sea.
I understand that the Qur'an itself does not list any pairs of seas that do not mix. My question is as follows;
1. Are Muslims posting photos of allegedly non-mixing sea pairs because they believe these sea pairs are an authentic example of what the verse in the Qur'an is talking about?
2. If so could they instead of just posting unlabeled photos, paste some essential related captions such as which sea pairs are shown, and the location of the photos taken to permit independant investigation where resources permit?
That opposing the fact that according to science both water should be mixed while in full contact.
Having sat through various fluid mechanics related courses myself, I can tell you that this is definitely not the case.
Basically a fluid of higher density will sink to the bottom while a fluid of lower density will float to the top. This is why helium enclosed in a balloon will cause the balloon to float above the surrounding oxygen, or why oil floats above water. It follows all the known laws of physics and fluid mechanics etc.
Basically if you boil water, and add salt until the most possible salt is dissolved, then cool the water, some of the salt will drop out. This is because according to the known laws of chemistry etc, the solubility of salt in water declines with a corresponding decline in temperature.
Now a cup is a very small model, over a larger model such as an ocean, it is possible to have greater variation of temperatures at different depths. Therefore if the polar wind chills the upper strata of ocean fluid, the salt drops out of the cold upper strata into a lower strata, this causes a density split between the upper and lower strata, with the strata with more salt being heavier.
All that being said, even though I'm not a fan of Dawkins metaphysical views, to be fair I think that what possibly might have happened here is that rather than willfully ignoring that the statement that the verse is talking about mixing of salt and fresh waters in 2 seas, what may have happened is a combination of Dawkins not having listened to the Muslim assertion carefully enough, coupled with the possibility that as a biological genetics expert, Dawkins may or may not be fully informed regarding the peculiarities of arctic and Mediterranean current flows as it is not his personal area of expertise.
Thus it may be fairer to state that Dawkins did not properly listen to or understand the assertion, and may not have given a properly informed response.
The difference between this and accusing Dawkins of lying is that to know he were lying, we would need to know that he fully heard and understood the assertion, and knew that the response he was giving was fraudulent.
To me I don't think it is fair to make all those assumptions from the limited knowledge in this video.
