What are three kinds of evidence scientists have found to support ocean floor spreading?

Oh, dude, scientists have found magnetic striping, age dating of rocks, and the distribution of earthquakes and volcanoes along mid-ocean ridges to support ocean floor spreading. It's like Mother Nature left us some breadcrumbs to follow, you know? So, yeah, those are the three main pieces of evidence that point to the fact that our ocean floors are actually moving and grooving.
