A Simple Slice of Science – Why is the sea salty?

This week’s question for Dr. Simple came in from a little boy who has just turned five and sometimes goes by the name of Spidey (you might find him here); He wants to know…

Why is the sea salty?

This is a great question  and Dr. Simple was delighted to “dive right in” and answer it!

Before Dr. Simple gets stuck in it might be a good idea to look at the definition of a sea and an ocean. Dr. Simple will use the word sea to mean both, which is commonly done, but there is actually a difference between the two words…

“seas are smaller than oceans and are usually located where the land and ocean meet. Typically, seas are partially enclosed by land.”
