Bingo. Apparently this is his first year teaching Oceanography after years of teaching marine biology. He told me about it being an affront to his beliefs. He got a biology degree. when I asked him if hes ever had to teach evolution, he told me that he's "fortunate that he hasn't been required to". I met the dean during my lunch break to ask why he's still teaching with those beliefs. He tells me that he was specifically chosen to teach for students that have a strong faith in creationism (I guess after enough letters from angered parents, he would have to answer their demands?). I realized on my way home that i should have asked why i was in that class. My parents believe in evolution, so that makes it really bizarre. About Ring Of Fire, Mid Atlantic Ridge, and the Hawaii islands, he says that they are unscientific and a creation of god.
I hope I'm not sticking my nose in this, but you could try another line of questioning with him (assuming he is subscribing the "the appearance of age", or Last Tuesdayism. In that specific case, you could ask why plate tectonics are necessarily wrong. If the world were created five minutes ago, would it be wrong to say that trees are formed from seeds? You can deduce how something came into being without necessarily invalidating his creationist beliefs. At least, maybe. I'm no philosopher and I doubt any line of questioning like this would end well.
