      Oxygen id trapped in ice and the voluem in the atmosphere does vary. One of the reason Mammoths and dinosaurs became some large was due to the higher volume of oxygen in the air.

      Even when oxygen reacts with things, the atoms of the element are still there – in Carbon Dioxide (CO2) or in water (H2O) – that’s what the O represents! It’s just harder for us to get to that way…
