Question

Why do the mountaineers carry oxygen cylinders with them? What is Biosphere?

Answer 1

Answer:

1.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.

2.The biosphere, (from Greek bios = life, sphaira, sphere) is the layer of the planet Earth where life exists.
