what is the percent salt compared to ocean water
If you've ever gone swimming in the ocean or been out fishing, you're probably well enlightened of the fact that bounding main water is very salty.
In total, oceans comprise most 97% of the h2o found on planet World, also as 70% of the Earth'due south full surface, therefore making nearly of the water reserves on the planet salty.
But exactly how much table salt is constitute distilled into the World'southward body of water h2o? There are some whopping estimates for this effigy.
What is the Total Amount of Table salt Content in the Ocean?
On average, there is approximately 35 grams of salt per kilogram of seawater.
There are i.4 sextillion ( sextillion !) kilograms of h2o in Earth's oceans.
To give y'all a visual of but how much this amount of h2o truly is, motion-picture show the number 1.4 with xx zeros following it.
1.400000000000000000000 kilograms of ocean water.
This measurement converted to pounds comes out to approximately 3.09 sextillion pounds of seawater.
Now, call back the 35 grams of salt per kilogram of seawater?
This means that, in total, there is virtually fifty quintillion kilograms of salt content in our oceans.
For visual purposes, 50 quintillion looks similar this: 50,000,000,000,000,000,000.
That'southward a lot of salt! So much, in fact, that information technology equates more or less to the mass of the Moon.
Why is the Ocean And then Salty?
When it comes to the reasons why the ocean is and so salty, there are a multitude of them.
First of all, information technology's important to make the stardom betwixt sea salt found in the ocean, and tabular array table salt similar the product we consume in and/or with our food.
Sea salt is primarily composed of a chemical compound known as sodium chloride, but it also contains other minerals including magnesium, calcium and potassium that likewise dissolve in water and mix with the already nowadays sodium chloride.
Over eons of time, this mineral integration occurs and combines with the salt from sources like rivers, sea beds, rocks and other entities.
Since this process takes millions of years, it's piece of cake to see how salt content can accumulate in great quantities over fourth dimension.
New salt is also being added over decades and centuries, albeit in much lesser quantities than what is currently in the sea already.
Still, like the mineral integration, these salt additions can pile upwards over fourth dimension and contribute to an ocean's saltiness.
What Other Factors Contribute to Ocean Salinity?
In add-on to the reasons listed above, there are also other factors that contribute to the general saltiness of the ocean water.
Rainwater that falls can be slightly acidic, which can land on rocks and dilute them gradually over time, and the more than rocks that are present near a trunk of water, the more likely that body of water will eventually get salty from the diluted rocks.
Backlog rain can also contribute to saltier bounding main waters due to the fact that more h2o means slower evaporation, and thus a greater area for salt to aggregate within.
The process of melting and freezing ice can have both positive and negative furnishings on the salinity of ocean h2o.
Traveling ocean currents impact ocean water salinity as well, every bit currents can carry both larger and smaller quantities of water.
Every bit you can encounter, in that location is no uniform way for common salt content in the ocean to build up over time; it largely plays out beyond unlike processes.
Which Ocean is the Saltiest?
One might presume that the Pacific Ocean would contain the largest amount of salt content since it's the largest ocean in the world.
Even so, this is not the case.
Of the major oceans of the globe, the 2d-largest Atlantic Ocean is actually the body of water with the highest salinity.
This is because some of the largest rivers in the earth (such as the Amazon) flow into the Atlantic Ocean, conveying all kinds of runoff and other minerals that brand the water content in the Atlantic so salty.
By contrast, the Pacific Ocean typically borders areas that receive more rainfall, which means more fresh water instead of saltwater.
For the aforementioned reason every bit the Atlantic, bodies of water like the Mediterranean Ocean and the Dead Sea are as well amidst some of the saltiest in the world, even though the latter two are both smaller in size.
Table salt in the Ocean: Last Thoughts
Every bit we've observed, the ocean makes up a bulk of the World'south surface.
These big bodies of water contain incredible amounts of table salt within them, with the Atlantic Ocean having a higher concentration of salt than whatsoever of the other globe oceans.
And so the next time y'all find yourself well-nigh an ocean or torso of saline water, remember not to drinkable it and opt for freshwater instead!
