Why are oceans salt water

Apr 25, 2018 · Salinity. Perhaps the biggest difference is in the name itself. Saltwater contains salt, or sodium chloride. Freshwater may contain small amounts of salt, but not enough to be considered saltwater. Ocean water has an average salinity of 3.5 percent. This means that there are 35 grams of salt dissolved in every liter of seawater.

The melting of icebergs adds freshwater – icebergs that formed over land but broke off ... Sharks cope with the salty water by generating lots of the chemical urea. This substance, produced throughout the shark's body, counterbalances the salt in the ocean water. In other words, there's as much salt in the seawater as there is urea (and other chemicals) in the water inside the shark's tissues. So sharks don't lose …When eating, they ingest a large amount of salty seawater. To get rid of this excess salt, sea turtles have large glands by their eyes that release salt in higher concentrations than the surrounding ocean water.

National Geographic Explorer-in-Residence Bob Ballard explains why such a basic question remained a mystery for so long—and where his team finally found the answer. Well, the water in our oceans is salty due to two separate sources: runoff from the land and openings in the seafloor. The main cause for salt in the sea (or ocean salinity) is rain washing mineral ions from land into the water. This refers to the acidity of rainwater – when rain falls, it wears down and erodes rocks. Seawater is toxic to humans because your body is unable to get rid of the salt that comes from seawater. Your body's kidneys normally remove excess salt by producing urine, but the body needs freshwater to dilute the salt in your body for the kidneys to work properly.
