What Makes the Ocean So Salty?

The ocean is salty because it has been collecting salt from rivers and rocks for a really long time.

Imagine you have a big bucket, and every day you add a little bit of salt to it, not much at first, but over years and years, the bucket becomes full of salt water. That’s kind of what happens with the ocean.

Rivers are like tiny helpers that bring salt from land to the ocean. When rain falls on mountains or rocks, it carries dissolved minerals, including salt, all the way down to the sea. It’s like when you mix sugar into water, the sugar dissolves and goes with the flow.

The ocean doesn’t just get salt once, it keeps getting more of it over time, like a never-ending game of adding sprinkles to ice cream. Even though some salt stays in the ocean forever, new salt keeps coming from rivers, making the ocean extra salty.
