subduction leads to orogeny.
Nicely played, sir!
I will have you know that I had to go look ‘orogeny’ up. Here I thought it had to do with some kind of redneck sexual thing when I first saw the word.
That said, I love rocks. Always have. They’re just kewl. Am quite fond of the Columbia River basalts. And trylobytes. You always get a great skipping stone.
