Hey Ocean what's with all the salt everyone jilling here for Dino's at nextspace La recently we got a question from Nene 7 1984 asking why the oceans were salty and everyone in the office kind of looked at each other and went what I'm going to assume she's not asking what the oceans are all sassy and bitter but instead of asking why there's salt in the oceans but not in our lakes and streams accept some legs Great Salt Lake I know people in Utah and internet trolls cheese first off the salt in the ocean is 90% the same chemical makeup as your table salt good old and AC sodium chloride is the only kind of Salter is there many varieties because assault is just a compound held together by and ionic bond what happens is an atom steals an electron from another and become negatively charged or an anion that is attracted to the positive cation and the two atoms bond so a lot of drink chemicals can come together and make salts and because of this the ocean is also made of a little magnesium calcium potassium and a polyatomic anion made of sulfur and four oxygens called sulfate but how does the salt get there from the rocks on lint actually according to the US Geological Survey dissolve CO2 in rainwater mix slightly acidic eroding rocks when it falls that's not the only trick water has sleep and H2O molecule is polar the oxygen atom Hogs the electrons so it's more negatively charged on one side and we're positively charged by the hydrogen atoms when salts are what are they break apart because the only thing holding them in their crystalline shape was that ionic attraction once the rain lands it flows downhill caring the dissolved minerals and ions to streams and lakes and rivers eventually the ocean the USGS also points out salt comes from inside the ocean to volcanoes and hydrothermal vents heat water so it can solve some of the basalt on the ocean floor salt to the mix but what is the ocean stay salty because saltas been accumulating there faster than it leaps some organisms use the salt or the basalt on the ocean floor take some back but thanks Detroit isn't even there's also the factor of evaporation when water evaporates the molecules spread farther apart in the magnetic pole for the vapor isn't enough to bring the ions with them as a result salt behind and it rains freshwater so long as the water doesn't get stuck Inland allow the Great Salt Lake swimming the levels will stay below .05% compared to the 3.5% who won the oceans so there's lots of water up here on the surface but it turns out there might be plenty more hundreds of miles below dr. Carin bondar guest host this at the dnews explaining trapped in the transition zone or the area between the upper and the lower mantle layers of our planet and Sciences even looking for it for decades this video was made because of your question we read them we store them we pick the ones we want to tackle that interest us or that we think you'll like keep sending them are away in the common or on Facebook and Twitter @d news and I'll see y'all next time
