Question

Drag each label to the correct location on the image.

Answer 1

The correct matches are:

1. Sea level (0 m) - 100%

2. Mid-level elevation (4,500 m) - 57%

3. Peak (8,850 m) - 33%

The level of oxygen in the atmosphere depends a lot on the elevation. The smaller the elevation, the higher the oxygen level, and vice versa, the higher the elevation, the lower the oxygen level. So we have a situation in which the oxygen level is the highest at 0 elevation, or rather at sea level. As we go to higher elevations, let say to around 4,500 m, the oxygen level is significantly dropped, which makes it difficult for breathing. If we go even on higher elevation, like 8,850 m, than the oxygen level will much lower, and a human will need to undergo intense long training and also carry oxygen with him/her in order to survive.
