Write a description of what you might see if you could explore a mid-ocean ridge in a vessel like the Alvin.

In your description, be sure to include the main features of the ocean floor along and near the ridge.

You would see basalt lava (splitting the immediately previously erupted basalt lava) being quenched (solidified) into pillow basalt, which would be immediately split apart by more erupting lava, and on and on in a never (well, almost never) ending cycle of seafloor spreading (building) episodes.
