What problem can mountaineers face due to decreasing air pressure in the troposphere?
Answer and explanation
Correct answer: Reduced oxygen availability
The governing concept is the relationship between altitude, air pressure, and breathing. As mountaineers climb higher, the atmospheric pressure decreases, so the number of oxygen molecules available in each breath also falls, even though oxygen remains about one-fifth of the air. This can cause breathlessness and altitude-related illness. Ozone, meteors, and radio waves are unrelated; therefore option A is correct.
