What Makes the Ocean Salty? What's Being Built at CMC?

When we had all the hot weather lots of people hit the beaches. That prompted David Wright of Arroyo Grande to ask: What makes the ocean water salty? Good Question.

First, rainwater is acidic because it contains carbon dioxide. When it falls, it erodes rocks and carries salt and minerals into rivers and streams. The runoff eventually makes it's way into the oceans. Second, seawater seeps into the rocks under the ocean floor. It gets heated up and escapes back to the ocean through hydrothermal vents carrying high concentrations of salt and other minerals.

The next question comes from Barbara of Morro Bay. She wants to know: What's the construction at CMC that you see from the highway.

That's going to be the new Mental Health Crisis Unit at the California Men's Colony. Construction started last January on the 50-bed facility that will cost $36 million. It should be finished this November.

I know you have a lot more questions so send them to goodquestion@ksby.com or, better yet, friend me on facebook. The only bad question is the one you don't ask.
