Did god create pockets of high and low salinity during the floods to keep salt and freshwater creatures both?

Question

alive?
How did he keep the fish from crossing the boundaries? How did he deal with different densities of the 2 waters to keep them from mixing? What about the cold/warm water species of both fresh and salt?

I'm sure the whole flooding of the earth had incredible mixing action, did he use some other force to prevent the mixing?

The Reverend Soleil: Yes but the process of flooding would mix these boundaries up, as well as disrupt any pre-existing pockets of differing salinity.

Blue T T: Last time I put salt in my pure water it dissolved pretty readily. They also sell pure water at your local fish store and this amazing thing called "Ocean Salt" that you mix at certain ratios in order to obtain the correct salinity for your fish/creatures.

buttercup: Hypothetical? This is not hypothetical, it is an issue god would have had to sort out, unless of course you don't believe in salt and fresh water species. Try throwing little nemo in a glass of water.

tim: here's a quote from talk origins.com:
"In addition to the answer provided, consideration should also be given to the great thicknesses of salt deposits found in sedimanetry sequences around the world. Where ocean circulation is restricted, hypersalinity can result, leading to the precipitation of a variety of salt minerals. This can be seen in restricted basins around the world today. Over time, large volumes of precipitated salt can develop."

"
Salt deposits hundreds to thousands of feet thick are found the world over. In the U.S., the Waste Isolation Pilot Plant near Carlsbad, New Mexico, disposes of radioactive waste in thick salt beds half a mile under ground. The nation's Strategic Petroleum Reserve is held in caverns dissolved out of salt domes, great columns of salt thousands of feet in length. Salt deposits around the world represent a tremendous amount of sodium chloride that has been extracted from sea water throughout geologic history, helping keep overall ocean salinity relatively constant."

Spiritual Gunslinger: Those fish have evolved in that area and are usually considered brackish water fish, they've evolved a sense of when and where to go during shifting tides. Most fish do not have this ability, if it were so then the great lakes would be full of sharks and other colder water marine life. Also, you're not taking into account all the salt water fish that feed off the top, and the plankton that they feed off (which would have died in fresh water).

Bah, I forgot what I was saying halfway through that last comment, the fish you claimed would know where to go during a change in salinity wouldn't know where to go because the super heavy rain that would be required to flood the planet would have an incredible mixing action.
Try filling a 5 gallon bucked up 2/3 of the way with salt water then fill over a short period of time the last 1/3 of the bucket with fresh water and take salinity measurements at different depths.

Answer 1

Scientist have kept track of the salt content of the ocean for hundreds of years, and it has been getting saltier all that time.

If you take the rate of increase and worked it back in time, the oceans would have been almost salt free about 4,500 years ago.

Many Christians know that that is about the time of the flood in Noah's day.

The Bible tells us that before the flood there was no rain.
With out rain very little salt from the land worked its way into the oceans, and the oceans stayed nearly salt free for the first 1,500 years.

Only after the flood has the rain been washing the salt from the land into the oceans, so ocean dwellers have had to adjust over the last 3,500 years.

Answer 2

the assumption here is there wasn't much depth difference between the two levels...ie, current salt water same depth, but only a few feet of freshwater on top....

However, 40 days of rain...hhmm...how tall is the mountains it covered up? There would have been a layer of mixed salinity, but still would have had fresh water on top, and ocean salt below...

Second...one of the neat things about the beaches here in africa is the rivers that flow in and out..... Tide comes in, so powerful, it pushes back up the river since the river doesn't have a high flow rate (when not in rainy season), and then tide goes back out. Saltwater fish come up river to the point they can tolerate, and then when tide falls back out, the fishermen pull freshwater fish.

Interesting...a two mile section of river...fish they pull depends on what the tide is doing. Guess this tells me the fish know which way to go (in case of flood - down deeper, or stay up higher).

Answer 3

Hey man, religion was created by governments as a means to control the people and retain order. Religion also allowed (and still does) people to fight other people guilt free if the call it a 'holy war'. This goes primarily for Christians though. think everything from the crusades to witch hunts and more. RELIGION SUCKS. Philosophy is the way that people should live. Discussing what they think and being able to back it up. It does not mean that everyone will get along, but at least they will know what they believe and why.

Answer 4

More generally it is completely unrealistic to claim, as Gould and many others do, that religion keeps itself away from science's turf, restricting itself to morals and values. A universe with a supernatural presence would be a fundamentally and qualitatively different kind of universe from one without. The difference is, inescapably, a scientific difference. Religions make existence claims, and this means scientific claims.
There is something dishonestly self-serving in the tactic of claiming that all religious beliefs are outside the domain of science. On the one hand, miracle stories and the promise of life after death are used to impress simple people, win converts, and swell congregations. It is precisely their scientific power that gives these stories their popular appeal. But at the same time it is considered below the belt to subject the same stories to the ordinary rigors of scientific criticism: these are religious matters and therefore outside the domain of science. But you cannot have it both ways. At least, religious theorists and apologists should not be allowed to get away with having it both ways. Unfortunately all too many of us, including nonreligious people, are unaccountably ready to let them.

Answer 5

There are many places on earth where salt water and fresh water don't mix, even when they are together. It's very interesting actually. Surprisingly enough, this fact is specifically mentioned in the Quran. Don't know where or why, it was just something my Muslim friend mentioned to me last week. Thought it was pretty cool.

Answer 6

Hmmm maybe Noah took different types of fish tanks onto his ark. But then, wouldn't the big fish eat the little fish? And how did the tigers on the ark not eat the deer?
The first answerer is right--the story should have been better thought out first.

Answer 7

In fairness, there can be distinct boundaries within the ocean waters where there are differences in salinity and temperature -- remember the movie "Sphere", where Dustin Hoffman remarks that "We're in the ocean, under the ocean, and there's a river"?

Answer 8

If God can create this whole world from nothing, then there
is nothing after that too great for a God like this to do. Just
quit thinking up hypothetical problems, and accept what
has already happened so many years ago, and enjoy the
life that has been created for us all.

Answer 9

Seeing as how the story of the flood was written and told hundreds of years before the existence of Noah I think it's safe to say that "God" had nothing to do with it.

Answer 10

Maybe there was no salt water in those days. Salt water is developed over years.
