Constantly refreshed by snow melts, springs and rain and rivers always flow to ocean. I think at some rivers it is salty still in the river but only real close to the ocean
I've watched a few different videos answering this question, and have yet to hear a consistent answer. I'm not sure where the truth lies on this question, or if there is a definitive answer. Some other theories involve tectonic fissures exchanging trapped water for new sea water erupting from deep vents and expelling all kinds of minerals with it, another states that evaporation leads to higher concentration of minerals being left behind, and finally this theory about rivers and rainwater. Interesting... Anyway, not sure this should be taken as a definite fact.
a different explanation says the rivers' chemical content is not matched by the ocean's chemical content, which comes from tectonic fissures where chemicals pour out of black smokers. This above video's flaw is that if rivers fed the salt into the ocean, land would somehow have to replace it';s salt to match the millions of years of rain washing the land.
Okay, but why the big lakes all over the world are fresh? I mean, even big lakes in the world has the same rain water from the same sources in the mountains, but they did not get salty in millions of years.
Crystals of "chloride"! Great!! Have you heard of chlorine? No? It is a gas... anyway... And coming up next , metallic helium! Further, that old theory has been proven wrong, long ago...
True fax by me its beacause every day milions of people pee in da water😂😂😂 Edit:all of this is not true so dont believe me😂😂😂 btw comment any hate i remove ur comment and ur dad jk😂😂lol get trolled
Looks like people forget that the biggest volcanoes are under the oceans I don't know any Rivers that has major volcanoes there are a few but never been there
I like your videos. I appreciate your thought to make these informative videos. However, I am not totally convinced with this explanation of salt in around 71% of water on earth which is salty because of a few rivers on land. May be I need to learn more about this theory. However, as I mentioned before, your videos are really helpful for a layman like me.
I just watched a video from NatGeo about this. They also thought it was the rivers, until 1979 when they found 'smokers' underneath. These smokers produces these crystal particles that makes the sea salty. They are spread out in the ocean ridges all over the world making our seas salty.
Just like gravity or Neolithic Polygonal walls all around the world nobody can really explain it, so many different theories. Still so much they don't know about this earth.
I saw another video vrom national geographic where they explain that ocean water reaches the core of the earth where it takes with it all kinds of minerals. It also said that we believed this (what you told) before 1979. Update?
This is only part of the reason oceans have a higher salinity content than freshwater biomes. Hydrothermal vents pump out massive amounts of salts into the oceans as well and they were only discovered in the 1970s.
