because of evaporation
AnswerAll oceans have salt in them. The average salinity of all oceans is 35 parts per thousand. Salinity does vary according to depth and location. Areas of the ocean located near onshore river runoff typically have a lower salinity. Areas near the tropics with high evaporation rates tend to have higher salinity.
Most water is found in the oceans where its salinity makes it difficult to use.
near the desert(30 degrese latitude) more water is evaporated than returned to the ocean by rainfall or rivers\canals.thereforth the ocean salinity near the deserts would be higher than most other latitudes
in the ocean
The top most layer has more salinity. But ignoring thermo-haline currents.
Wait, I thought you guys were supposed to be answering me.
Most water is evaporated from oceans.
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
nobody owns oceans...
there are no oceans in Spain
No oceans are in Mississippi...
