Well, you can't comb the hair on a bowling-ball - if everything is
moving, at least one convergence and one divergence are inevitable.
But I believe conventional wisdom says the Pacific Ocean is the scar
left by a really big collision which ripped out the Moon. Frivolously
I might suggest that the continents are just trying to slump into that
hole. Problem: I believe conventional wisdom also says that Pangaea
has converged and split up more than once.
