The higher into the atmosphere the plane ascends, the thinner the air is. This is the reason oxygen is required. The United States Parachute Association states oxygen use should begin at 15,000' above ground level.
Because of high altitude sickness which is affected by climbing up high were there is high altitude. High altitude is were there is to much oxygen up high, if you breech in to much oxygen you could faint.
Oxygen density decreases as altitude increases. This is due to the decrease in atmospheric pressure at higher altitudes, which results in a lower concentration of oxygen molecules. Therefore, the higher the altitude, the lower the oxygen density.
It depends on the grade
No mountains in the UK are tall enough for the air at the summit to be appreciably thinner. The only people who'd need bottled air on the summit are those who'd need it anyway, at any altitude!
High altitude places, such as mountainous regions, can affect individuals differently due to lower oxygen levels. It can lead to symptoms like shortness of breath, headache, and fatigue, known as altitude sickness. People may need time to acclimatize to the higher altitude to adjust to the decreased oxygen levels.
Altitude sickness can be treated with oxygen therapy
Alison Hargreaves. On 13 May 1995 she reached the summit of Everest without the aid of Sherpas or bottled oxygen.
Lydia Bradey from New Zealand in 1988 was the first woman to climb Mount Everest without bottled oxygen
No, fish cannot survive in bottled water because it lacks the necessary oxygen and nutrients for them to live.
Yes, it is recommended to bring extra oxygen for travel to high-altitude destinations to prevent altitude sickness and ensure proper oxygen levels in the body.
Hot air balloons typically do not require supplemental oxygen until altitudes of around 10,000 feet (3,048 meters). At this elevation, the air density decreases significantly, which can lead to reduced oxygen levels. Pilots may choose to fly higher, but they should be aware of the potential for hypoxia and the need for oxygen systems if exceeding this altitude. Safety regulations and personal comfort levels will also dictate altitude limits for balloon flights.
