Salty Water = Proof for Creationism?

I recently started teaching at a small home school. I had no idea what I was getting into until I started teaching "Biology" <--- note the quotations! I opened up the book expecting to find hard facts and good lessons but instead it started off by saying how all animals were created on the 5th day. *Cue immediate facepalm* Now I'm supposed to read this to my class, which took some hard effort and displacement of my consciousness. I felt like such a fraud!

But THEN I came across a small paragraph titled "Proof of creationism". It discussed how the salt from the oceans is gathered from the rivers and streams that run from the mountains to the oceans, and how the water picks up the salt from the sand and rock it runs over. Then they go on to say that if the world was in fact billions of years old then the oceans would be a lot saltier, so therefore creationism! I just couldn't teach my class that. There was absolutely NO WAY! So I conveniently skipped it and went on to teach them what little hard facts there were in the book without the "If god hadn't created these creatures with this... " and  "Praise god for giving us this creature!" Is it a bad thing that I choose to skip the god stuff? Am I supposed to be teaching them lies if that's what I'm told to do?

I must say though, that I have never heard that argument before. It's usually the "Without god you would kill people" and "Then where did everything come from?" arguments, not salty oceans! I'm not even sure I would know how to respond if a theist approached me with that.

Teri, you didn't say if the home school is paying you to teach. If so, and if you need an income, you might want to start looking elsewhere for employment. I wish you well.

I'm retired and in ten years only two people have told me they accept every word in the bible as true. I realized that I had no reason to do more than greet them, and from then on that's all I did.

Yes I am being paid, but the good thing is that it is a temporary position so I end in August.

Oh my lord.  My tuppence worth is that it's your job and they're paying you, so you've got to do what they say.  What they're asking is not illegal although perhaps the morality is questionable.  If you want to introduce anything different, I think it's your duty to consult your employers first.

I'm not introducing anything new. I'm just cutting back on all the "praise lord for the creatures" stuff. I'm teaching them all the good stuff that's in the book, and thankfully it only seems to be the Biology subject that's so god filled.

It must be a little galling.

Although I understand completely about your frustration on the matter, however since this is a private institution and you are being employed by them with a salary, you have to follow the curriculum they have set forth to be taught at their schools. 

Regarding why the Oceans don't get saltier? That has to do with the fact that the salinity concentration in water is very small. For 1 liter of water, 35 grams or 3.5% of it is salt. Now for it to actually get to a point of the ocean becoming completely salty will take a billion or years. However like everything else in mother nature, there is a system of natural balance. One of the reason why the salt concentration gets reduced in Oceans is because of plate tectonics caused by the volcanic molten activity beneath the sea floor. As it creates new ocean floors on top of the old ones.

Also melting of icebergs help bring the new flow of additional volume of water in oceans causing the concentration of water to increase thus diluting the salinity concentration.

So next time they if tell you about sea water being proof of creationism, tell them that and they will think twice of ever repeating that nonsense to you lol

Adam, how does new ocean floor reduce salinity?

Also, sea ice comes from ocean water, just as much as it adds to it. It just has to go through an extra gas state in the atmosphere. I.e., there's no new water coming from anywhere to reduce salinity, unless you're talking about the kind of melting that significantly raises sea level.

I am not a geologist but from what I remember from my education in Earth Science and Geology, convergent boundaries creates new continental plates which are lower in density causing the ocean floor which is filled with sediments and salts to get pushed under it. Therefore the concentration of the salt is reduced.  

Well the icebergs don't have any salt in it since the density of water cannot carry extra molecules in it when forming a solid. So its just pure water when it forms and melts. I am talking about more so icebergs that come from melting of glaciers. You have to look it in terms of Molar concentration of salt in a water solution. That is the salt concentration is getting diluted

For example

1Liter ocean water contains 35grams of NaCl and Molecular weight of NaCl is 58.44g/mol

35gramsNaCl / 58.44g/mols = 0.60 mols

Now if you that in 1 liter of water, you will have a Molar concentration of:

0.60mols / 1 Liter = 0.60M

Now if you add lets say 1.5 liters of water, then lets find out how much the salt concentration diluted

0.60M * 1Liter = X * 1.5Liters 

x = 0.40M

In terms of % = (0.40 / 0.60) * 100 = 66.6% 

So your salt concentration got diluted by 66.6%. Now if you look at in terms of an oceanic level, the dilution is much much greater. So ocean water doesn't get saltier not because of god but because of chemical properties of water. 

Perhaps this can help explain better

The amount of ice present in a particular area of an ocean influences the level of salinity. When sea ice forms, only fresh water is frozen. This means that the freshwater portion of the ocean water is reduced and the salt that is left behind increases the salinity. In areas of oceans where icebergs are present, water salinity levels are very high. Polar seas, however, are influenced by melting ice. This increases the amount of freshwater with the result of decreasing the level of salinity in these areas.Read more:

@ Adam  Go you!

How about the "Holy Salt" that the Catholics have. It can prevent burglary if used correctly.
