Question

Give a reason why at the top of a mountain a mountaineer is likely to nose bleed

Answer 1

Answer:

Mountain climbers often get nosebleeds at high altitudes because as the amount of oxygen in the air decreases and the air becomes drier, blood vessels inside your nose can crack and bleed. That's the origin of the term “nosebleed seats” in reference to seats at the highest point of a venue.

Answer 2

Climbing high

Nosebleeds can be caused by being up in a very high altitude. As you climb higher, the amount of oxygen in the air decreases. This makes the air thinner and dryer, which can in turn cause the inside of your nose to crack and bleed.
