Suppose you have 2 core samples. Sample 1 is from ice that is 2 meters deep and Sample 2 is from ice that is 100 meters deep. What is true about the CO2 levels in the 2 samples?
The CO2 levels from the 2 samples would be the same.
The CO2 level in Sample 1 would be lower than Sample 2
The CO2 level in Sample 1 would be higher than Sample 2
There is no way to tell the difference.
None of these

  1. Ice from 100 m deep would be much older. What do you know about the presence of CO2 millennia ago?
