How does the salt get into the sea?
How does the salt get into the sea?

Many of us love salted peanuts and French fries. Without salt, our food would hardly be enjoyable. Just think of the boiled egg for breakfast without a pinch of salt! But where does salt actually come from?
Perhaps an experience that almost all of us have had will help: If you get a little seawater in your mouth while swimming in the North Sea or the Mediterranean, you'd rather spit it out again straight away. Seawater tastes salty and sometimes even a little bitter. So there is salt in the sea. But how did it get there? And what role does it play there? We will see that salt is like a motor for the large ocean currents, without which the creatures in the ocean would not have enough oxygen to breathe. And salt also plays a major role in our climate!
