Thank you for these links. I had recently read on wikipedia [1] about how plate tectonics may have started on the young earth, and I was fascinated by the idea.

Thank you for these links. I had recently read on wikipedia [1] about how plate tectonics may have started on the young earth, and I was fascinated by the idea.
