(Photo was taken in San Francisco yesterday. It's possible the sensor was in the sun.)
(11:09:33 AM) Me: Casey asked me if the strait of gilbraltar were closing or opening -- I didn't know for sure.
(11:09:42 AM) Kimberly: : heh, no clue
(11:10:01 AM) Me: So now: Would you like to know about the geology of northern africa and the african/eurasian plate boundary? I had to find out.
(11:11:02 AM) Kimberly: : of course I would like to know!
(11:20:10 AM) Me: *grin* The African plate is moving north pretty fast, but most of the compression is happening in (causing, in fact) the Atlas Mountains, not closing the straits.
(11:20:49 AM) Me: The straits gradually opened from about 25 million years ago to 5 myo, but have been slowly, slowly closing since, with most of the compression happening elsewhere in the mediterranean, local N. African mountains, and 45% of it in the Atlas Mountains.
(11:21:43 AM) Me: I said to Casey, "You knew I couldn't not know, once I realized I didn't know." Casey said, "I know. It means I don't have to do my own research."
(11:21:52 AM) Kimberly: : lol
