Seafloor Spreading

In this video, we take a look at the concept of seafloor spreading and the four major pieces of evidence that support it, with a focus on the observed alternating bands of magnetism preserved in the rock on either side of a mid-ocean ridge.

I watched this like 5 times already. Watching this is a good preparation for a test.

At the end of 13 minutes, I was thinking, is it over already? That was an awesome video. A little long to play in class, but still good, I can play parts of it. And no ads, even better.
