The higher you go up away from the Earth's surface, the less oxygen can be found in the air and more of gases we don't need to breathe in.
So, as the mountaineer goes higher up, breathing becomes harder and your body works slowly, reducing reaction times.
By carrying an oxygen tank, the mountaineer can always be breathing the perfect concentration of oxygen they need at all times.
Climbers carry oxygen cylinders because there is less usable oxygen at the highest elevations. The ability to function is greatly reduced without the use of supplemental oxygen.
When climbing any high mountain the air that we breathe gets thinner. We need to breathe oxygen from a cylinder to survive at the high altitude.
Mountaineers carry oxygen cylinders because the higher you got the thicker the air gets and there is less oxygen
A climber carries an oxygen cylinder on their back because it helps him/her to breathe easier. On high altitude mountains like Mount Everest the air is so thin it makes it very hard for anyone to breathe without extra oxygen from a cylinder.
the air becomes rarefied and has a very low oxygen
Because they find themselves in environments of little or no oxygen, and oxygen is essential to life.
At extreme altitudes, the air becomes rarefied and has a very low oxygen concentration. This can lead to a condition known as hypoxia, which is deprivation of oxygen to the brain, which can cause loss of consciousness, paralysis, and death.
because the higher you go up a mountains are the less oxygen there is.
Because at great heights ie up mountains the air becomes 'thinner' this means there is less oxygen and so it is harder to breathe. So they carry the oxygen so that they can continue up the mountain otherwise they will be unable to coninue because it is dangerous.
because the air gets thinner and thinner the higher you go, the oxygen is for survival.
If you mean 'Why do climbers carry oxygen cylinders on mountains' then that is to survive. On high mountains like Mount Everest the air (oxygen) is so thin you need help to breathe, so they use oxygen from a cylinder.
They have to carry oxygen cylinders with them as it allows them to breath at high altitude. The temperature also decreases as we go higher and higher.
It is because at high altitudes the oxygen is not sufficient..........
Mountaineers carry oxygen cylinders with them on high altitude mountains like Mount Everest. This is because the higher the mountaineer climbs the less air there is to breathe.When you travel in an aeroplane at a high altitude the plane will be pressurized. A cabin air pressure at cruising altitude is lower than air pressure at sea level. At typical cruising altitudes in the range 11 000-12 200 m (36 000-40 000 feet), air pressure in the cabin is equivalent to the outside air pressure at 1800-2400 m (6000-8000 feet) above sea level.
Because there is less oxygen, due to low air pressure.
