Re: [Phys-l] atmosphere

An expert on these matters is Lynne Margulis at U Mass. You might look at Margulis and (Dorion) Sagan, <What is Life?> (U. of Calif. Press 1995). I've not yet started on my copy, which I acquired in September after attending a lecture by Margulis.

I'm teaching about planetary atmospheres in astronomy. I've read about
sunlight breaking down methane and ammonia in Earth's ancient atmosphere
to produce hydrogen, carbon, and nitrogen. I guess this is called
photodissociation. I'm no chemistry expert, but does anyone know the
chemical reactions for this? I looked online but could not find them, only
water forming hydrogen and oxygen, and oxygen forming ozone.
