This seems like a perfect time to ask why this is the case? A few years ago, I did some intensive study of plate tectonics and orogenesis, and I noticed that, as you say, there are few convergent boundaries on land, but I could never figure out why. Surely, when converging plates cause the closing of an ocean, it also results in terrestrial collisions.

Can anyone shed some light on this for me?
