All the bodies of water on Earth are defined as either "salt water" or "fresh water." But did you know that all of Earth's water contains a certain level of dissolved salt? Even the rain that feeds these bodies of water co...read more

Have you ever wondered why with 2/3 of our world covered in water, we can't drink it? Some Sciences say we came from the sea, if that is so, why is it that we can only drink fresh water? We hear all the time that our sou...read more

The sea water contains about 35 g/l of salts and, for this, it has a slightly higher density (1,023 g/cc) than pure water; about 29 g/l of this salt are made of NaCl and the remaining is formed by the following ions, in ...read more

The process of water in the ocean becoming "salty" is a thoroughly verified and scientific sequence of natural occurrences. Knowing about these is a cornerstone of oceanography. Water is always traveling. Through the w...read more

In my Year 8 science class, we did an experiment with sea water. We removed the sand using filter paper and left the water to evaporate. When it did, there was a layer of salt crystals left behind. But if we had done the s...read more

The salinity of seawater is measured in parts per thousand and a good average is about 35. That is the same as saying a glass of water contains 3.5 % salt . Interestingly, even if the salt level may vary, the minerals that...read more

This sounds a very plausible theory but what and where is your evidence? If this is true why are rivers and lakes never salty unless linked to salt deposits. Additionally how did the sodium chloride get into these rocks an...read more

When the sea first formed, it wasn't salty. The sea developed its saltiness over time. The salts and minerals were moved into the ocean through runoff. Rainwater and runoff dissolve rocks and minerals. The minerals are ca...read more

The reason that sea water is salty revolves mainly around the concept of the evaporation of salt water. Rivers flow into the sea bringing with them very small amounts of salt. This process is called weathering. We don't ta...read more

The salt in the sea comes from the eroding lithosphere of this world, supplemented by eruptions from deeper down. Space debris also makes a contribution. There is also evidence that salt has come to the Earth from the plan...read more

All rivers run to the sea... and so does everything floating within them. As it rains, the moisture hits the earth and disturbs it, soaking up salty deposits and carrying them along with it until it reaches the sea. Th...read more

Our ocean's contain as much as 50 quadrillion tons of salt. Our fresh water is not entirely free of dissolved salt either, even the rain has traces of it in it, picked up through its long travel through the atmosphere. T...read more

Believe it or not: the world's oceans and seas used to be full of fresh water! Over time, however, various elements gradually washed into the Earth's major bodies of water. Chloride and sodium flowed in more than other ...read more
