Oxygen Pressure Gradient

I honestly don't remember where I obtained this image, but I believe that it was from the course materials of a Geology class I took.

There should just be a single horizontal line for the altitude of Everest, with the corresponding vertical line to the mbar axis.

Re: confusing

Thanks for the comment! The graph is showing how pressure changes with altitude. Although the picture doesn't really look like Everest, the tip of the peak in the image corresponds with an elevation of ~8900m to approximate the pressure at the summit of Everest.

With this graph, anyone wanting to climb a 12,000m peak on earth can know to expect only about 150mb or pressure... ;-)
