Question

10. Why do mountaineers carry oxygen gas cylinders with them?​

Answer 1

Answer:

Mountaineers carry an oxygen cylinder along with them. It is because when they climb mountains, as altitude increases, the amount of oxygen level in the atmospheric air decreases as trees are not found at higher altitudes. As a result, mountaineers suffer from dizziness.

Answer 2

When they reach higher altitudes it will become difficult to breath that's why mountaineers carry oxygen cylinder with them
