Question

people have to carry oxygen cylinder, whenever they go for mountaineering.

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. It can also lead to hypoxia.
