Salt is dissolved from the Earth and transported by rivers in oceans and seas.

∙ 15y agoNo, they havn't always been salty. The sea gets salty because when rain falls on the land it gets absorbed into the soil. It keeps going until it enters a stream or river. On its journey to the river or even in the river on the journey to the sea, it collects minerals, one of those is salt! So, before it had ever rained, you could actually drink the sea!

∙ 15y agoWhen the earth formed, those minerals from which it was made that are readily soluble (such as sodium chloride - salt, but also other minerals) in water dissolved into the water found on the planet. This water filled the lowest depressions to make the oceans and these oceans were and are salty.

∙ 14y agoAll rivers, streams and such, lead to the ocean. As the streams flow, they simply pick up salt from rocks, and other such stuff that may have salt, and carry to the ocean. so graduelly the ocean gets saltier every year. Another answer: I heard or read somewhere, that as mankind harnesses the water from the major rivers, less fresh water reaches the oceans. This, in turn, makes the ocean salt levels higher, because there is less fresh water to dilute the salt content.

Why is polar water saltier than other ocean water?
It is the other way around. The polar seas are the least saline of the worlds oceans, due to low evaporation and heavy freshwater inflow from rivers and streams.
How do scientists explain the fact that some landforms that are far apart and separated by oceans appear to be related?
Erosion
Is the thames saltwater?
The nearer it gets to the sea, the saltier it gets.
What are two major ways that an ocean can become saltier?
add salt
Why does the ocean water get saltier after evaporation?
If water is evaporated salt remain in the ocean.
How are oceans getting saltier day by day?
Only God knows
Why oceans are not getting saltier?
well,it can't get more saltier and it can't get less.the denser the water is,the saltier it'll be.the less denser,the less salty it'll be.its the same amount of salt,just different density levels.
Do the oceans get saltier over time?
no they don't
Do oceans near the poles tend to be saltier?
The water is saltier at the poles, and less salty at the equator.
Why are the Dead Sea and the Great Salt Lake ten times saltier than the oceans?
It is saltier because it has no outlet to the sea.
How much saltier is the dead sea than the oceans?
The Dead Sea is 33.7 % Salinity - The oceans average 3.5% salinity. So the Dead Sea is Roughly 10 times a salty as the Oceans. ----------------- I found another source (wikipedia.org)that states that the Dead Sea is 8.6 times as salty as the sea.
Why aren't the oceans getting saltier?
My off-hand guess would be that they are getting less salty on average as fresh melt-water from Greenland and the polar caps enters the oceans.
This inland saltwater sea is the largest ocean in the western US and is saltier than the oceans?
Great Salt Lake
Why is the Arctic Ocean saltier than Oceans further south?
It think that salt stays in the water because it gets frozen.
When sea water evaporates the salt is left behind you might think this would make the remaining water Saltier but in fact overall the ocean is not getting Saltier why do you think that is?

How moon affect the oceans?
by getting closer to the oceans.
Why is the salinity of the ocean evidence that the earth is not billions of years old?
There is more salt going into the ocean then what is being removed. In the end, then, the oceans are getting saltier an saltier. Suppose we assume that the oceans originally had absolutely no salt in them, and that all of the salt in them today came from the hydrologic cycle. Well, based on the inventory that scientists have done, you can actually determine how long it would take for freshwater oceans to become as salty as they are now. It turns out that the data indicate it would take, at the very most, sixty-two million years to turn from freshwater oceans to salt water oceans with the salinity we see today. This makes it hard to believe the earth is billions of years old, after all, if it were billions of years old, why aren't the oceans a lotsaltier? No one has a convincing answer to that question. Secondly, since the salt water organisms have always been salt water thriving organisms, God made the oceans saltwater.Sources : Exploring Creation with Physical Science
