How do you fancy a big question? Do sneezes have accents?

Hello, welcome along. My name's Dan. This is the Fun Kids Science Midweekly. A little bonus

popping up every Wednesday answering your science questions and loads more to help us explore

the universe.

Today we'll find out why the ocean is salty, how clouds make rain, and, yeah, why you might

sneeze differently to another person.

Let's get into it.

Hello, my name is Jack, and my question is, why is the ocean salty?

Why is the ocean salty?

Thank you for this one, Jack.

Well, most seawater comes from rainwater, and rainwater comes from seawater.

It's a big cycle. We'll talk more about that in a second.

Now as rain falls on the land, as it drops down from the sky, it hits the earth and it makes

its way to rivers eventually that all flow towards the sea. And on its journey, it bumps into rocks

and it runs through mud and overland and it washes along the sea. And on its journey, it bumps into rocks and it runs through mud and overland,

and it washes along the bottom and rides up to the top, and it picks up minerals and salt along

the way. These come as ions, which are tiny atoms from the salts in the rocks that the water

hits. So it's on its journey, this water, it keeps flowing, it keeps hitting

everything, and as it goes, it collects loads of salt and minerals, and it heads into the ocean,

which makes it salty. And there are also underwater volcanoes and thermal vents down in the

ocean that release more salts still. Now there are some seas that have

even more salt in them than others like the Dead Sea, which is over in Asia in the Middle East,
