Rosie Coates answered on 17 Mar 2014:
The sea has become salty over millions of years because of something we call the water cycle. When rain falls the water runs over the rocks on the ground and some of the minerals dissolve in the water. This water runs into seas where it evaporates to become rain and the cycle begins again. When the water evaporates the salt is left behind in the sea and so over time the seas became full of salt water.

That is so good to find out because I always used ask myself why. It’s salty now I know

I agree with Rosie and I think it’s salty because when there is snow people put salt on the snow to make it melt, so the salt could go in the sea.
