Yall Im struggling, if u cant read it, the question is “why does a mountain climber need an oxygen supply at very high altitudes, even tho the air still contains 21% oxygen?

Why does a mountain climber need an oxygen supply at very high atitudes, even though the air still contains 21% oxygen? A mountain climber needs oxygen supply at very high altitudes because the temperature and air pressure is lower than they are at sea level. ... The higher altitude the more thermal energy.

Explanation:

Because it is harder to draw breath in. And the cold

Explanation: At higher altitudes, it becomes more dangerous, and you can develop altitude-related illnesses such as HAPE and HACE. I read a book called Into Thin Air, and in the book the author goes into detail on the details/complications of climbing Mt.Everest and oxygen needs. Mountain climbers use canisters of oxygen called Supplemental Oxygen.

i think it’s c but i might be wrong. if i am let me know! have a good rest of your day as well!
