Ask Dr. Universe: Why is the ocean salty?

Dr-Universe-230PULLMAN, Wash. – At first, I thought the answer to your question might take us deep into the ocean. But it turns out the source of our salty seas is actually on land.

My friend, professor Steve Katz, and I took a walk along the shore of a nearby river to investigate.

Katz is an environmental scientist here at Washington State University. He pointed out some big rocks along the river. That’s where the salt comes from, he explained. Yep, it all starts with rocks and dirt.
