Assalamoalikum and welcome back to Orange Shots
You can observe two colours of water in this Chinese Port
you can see the brown water and the blue sea water
You'd see many similar places if you visit Google maps or Google Earth
You'd observe 2 colours at Indus river delta
Brownish and bluish
You'd observe similar colours at Mississippi river delta too
same brown and yellow colours
You'd see same colours near Alaska
In fact you'd observe same colours at every river delta in the world
Rivers bring clay with them when falling in a sea
Rivers are fresh water with a density of 1.0 kg/cm2
While density of seawater is around 1.025 kg/cm2
Simply speaking, sea water is heavier
than the river water
Now talking about the phenomenon where water of the 2 seas doesn't mix
we should become aware of few things first
There are far too many seas in the world
The oceans are only a few
Depending upon whom do you ask they are 5 or 7 in number
if you count North and South Pacific & Atlantic as separate oceans
then they'd be 7 in number
Three properties of water determine whether they can be easily mixed or not
Water has many other properties of course but these three play key role in mixing them
The first important property is called "Thermocline"
this is dependent on water temperature
two bodies of water at different temperatures are hard to mix
Second property is called "Chemocline"
this is dependent on a water's chemical properties
two water bodies would mix easily if they're chemically similar
in case they are dissimilar in chemical properties
they'd be equally hard to mix
then comes the third property, it's called heliocline
Heliocline depicts the difference in tensile strength of two bodies of water
similar tensile strength means the water bodies will mix up easily
Combined together, all of these three properties of water are called "Ocean Clines"
Not very long ago, it was thought that
that the sea water of all bodies of water around the world is same in properties
it's fairly mixed up and similar Looking too
until 20-odd years ago when during a diving operation in the Mediterranean sea
& while crossing the straits of Gibraltar, he observed something
On the east of Gibraltar is the Mediterranean Sea
and when you move to the west of Gibraltar Strait you find yourself in Atlantic Ocean
During this diving operation when he crossed over from Medi to Atlantic
He suddenly felt that something has changed
Later on it was revealed that while the source of water in Medi is the black sea,
The suez canal
and of course the Atlantic ocean itself
but as the Mediterranean sea is practically surrounded by all the land
all of their fresh water falls in the Mediterranean
This not only causes a slight water level difference between Mediterranean and Atlantic
it's water properties are slightly different too
at the point where Mediterranean Sea meets Atlantic ocean,
although Mediterranean sea is a part of Atlantic Ocean itself,
one might feel a boundary between the two water bodies because of ocean clines
Because of a difference in Ocean clines, both water bodies don't mix up instantly
but, although they aren't mixing up instantly,
and while you may observe a boundary between the two
You can feel this boundary underwater
You cannot visually see the difference on the surface
at the surface, both seem and feel commingled
Both feel connected and Joined
BUT
there's another interesting thing here
Moments ago we talked about 7 Oceans,
South Pacific and south Atlantic Ocean meet each other close to Cape Horn
Cape horn is the place where, when you're crossing the Oceans
from Atlantic to Pacific or vice versa
you'd see something for the first time that'd be observable to the naked eye
While the rest of the oceans don't mix up instantly too, but you can't observe that difference by eye
you'd observe the difference only while you're either diving underwater
or examine the water samples in the laboratory
only then you'd be able to know the difference
South Pacific and South Atlantic are the only Oceans
where's you'd observe the difference in colour if you watch keenly
but even this difference in colour isn't observable if you're looking for it
So yes, it is a fact that you'd observe that the properties of the two oceans are different
that is hindering them to mix up together
But you can't observe this phenomenon by eye, but it's there
Now let's talk about the photos and videos that i showed you in the beginning of the video
Have I seen this phenomenon myself, yes, many times ...
I have seen this phenomenon near Mississippi river
I have seen this phenomenon in a port in China too
I have seen this near Chittagong in Bangladesh,
it's very common and you can see it there
I have seen this near Brazil and Uruguay too
Important thing is, these videos and photos don't depict two seas or oceans
because despite the fact the two seas or oceans don't mix up instantly
you can't see this happening by eye
all of these videos depict a fresh water and a sea water body
Sea water is never brown in colour
it's Greenish, Greenish Blue, Dark Green
and open sea is usually Blue
as you may see that we are at open sea and the colour is Blue everywhere
Now in the beginning of video I said that salt water is heavier than fresh water
when river water falls in the sea, they don't mix up initially
Fresh water floats on the top and salt water jets in from bottom
This sea water forms a wedge under fresh water from rivers
on the surface you might see a clear line demarcating fresh and sea waters
appears as if someone has drawn a line
it's definitely fascinating to see
i observed this phenomenon for the first time in Nile River
that was back in the year 2000 or 2001
about 21/22 years back, and it was really really ...
what should i say ...
I was so thrilled to see all that
it looked fascinating
But does this water always stay like this?
or as in the case of sea and oceans, despite the difference in two sea and oceans
but do they never mix?
does this boundary always stays?
The answer is NO
I'm sure, you guys must have drunk Rooh Afza in Pakistan and India
Initially this Rooh Afza doesn't mix in the water
it needs to be stirred
Interestingly enough, even if you don't stir and leave it as it is
as the water molecules are always in motion
and i'm sure you guys must have performed this experiment in primary class
it mixes up itself
Same is the story with the Oceans
they can't stay separate forever
if you consider another aspect
apart from sea evaporation and rain at sea
a huge portion of sea water is these rivers
these rivers bring the fresh water from land to seas
they are a super big source (of water)
They are a part of a bigger ecosystem
Water evaporates from sea, forms the clouds and it rains or falls snow over the land
This snow then melts, the water comes in rivers and falls back in the sea
it's a cycle that keeps running
if all these waters stay separate then this ecosystem will cease to and exist
So, coming to the final conclusion, are there places in the world where the oceans don't mix?
Yes
Obviously that is true
But can you see it with your eyes? NO....
You can't see it with your eyes
Last and final thing... All these videos, that claim on showing
two oceans or seas meeting together... are they genuine and real videos?
The videos are real but they are captioned incorrectly
These videos show a fresh water body and a sea... not the two seas...
Please Stop believeing on these videos
you shouldn't be following an illogical thing at all
In my view, people are being misguided over here
always consider evaluating something before believing it unnecessarily
Don't let anyone insult your wisdom
Islam never asks you to believe such things, Islam tries to make you ponder
