Nose bleeding may occur at a high altitude because:
- the atmospheric pressure decreases.
- the oxygen content of atmosphere decreases.
- the atmospheric pressure increases.
- there are strong air currents at the high altitude.

Answer
the atmospheric pressure decreases
Reason — At higher altitudes, atmospheric pressure decreases but our body pressure remains the same. So, inside pressure becomes more than atmospheric pressure which causes nose bleeding.
