sea is salty


Sea is salty, we all know that. But have you ever wondered why there is so much salt in the sea? Even if you never notice I am sure maybe someone else, like your child, asked about it.

Hence, where all this salt came from? When I was a child our teacher in primary school was telling us a story of the origin of salt. 

So the story went like this: there was a ship carrying salt and it sank in the middle of the sea.

We forget that the water cycle and the life cycle are one.

But the story made no sense. Because the ship must have been the size of Earth and also that does not say anything about the origin of salt.

Anyway, thankfully, I grew to become a geologist and I found out finally why. 

Hence I am sharing in this episode why the sea is salty. A hint for you: there is nothing to do about a ship.

On the contrary, the sea is salty because of the story between the water cycle and rocks.

Therefore this is a natural process of Earth which ends up to make the sea salty.

But also the salt is also a source of food for the sea animals and vegetation. Learn more in this episode.

Salt is born of the purest parents: the sun and the sea.


So what the story you were told about the salty sea? We will like to hear about it below.
