Title: Where is carbon trapped in the Earth?
Post by: Lewis Thomson on 10/02/2022 10:30:23

Donald wants to know answers to this question

"The Earth's original atmosphere had CO2 and no significant O2. Biological processes eventually sequestered that CO2 into glucose and other organic molecules leading to the "oxygen catastrophe". How much carbon is trapped?  Coal was produced way after the oxygen catastrophe when atmospheric CO2 was a thousandth of the primal CO2 and there is so much coal! Where is all that original CO2?"

Mostly in chalk and limestone deposits.

Hi everyone, can you know that most of the carbon on Earth is stored in rocks and sediments. And the other carbon is trapped in the ocean or atmosphere.
