Hi, I hope this question is appropriate for this forum - if not can anyone suggest a place to ask it?
There is a lot of carbon based matter around, on an in the earth. But,as I understand it, other than gaseous forms all the other liquid and solid forms have been generated/created by living organisms. This includes oil, coal, graphite, chalk, limestone as well as biomass.
Q. As Earth formed in the early days of the solar system - where did all the carbon come from and in what form did it exist? If it was gaseous then what gas? and does that mean that Earth formed with a ready made atmosphere?
Just wondering
Thanks
John
