Question

While climbing the mountain, more amount of energy is required. Identify the correct reason.

• A. Because the amount of oxygen at height decreases
• B. Because at height pressure increase
• C. Human body is adaptable for normal pressure and oxygen
• D. All of these

Answer 1

The correct option is D All of these

Lack of oxygen causes high-altitude sickness. As altitude increases, the air becomes "thinner," which means less oxygen is in the atmosphere.

The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation.

At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.

At high altitudes, the lower air pressure makes it more difficult for oxygen to enter our vascular systems.

Hence while climbing the mountain, more amount of energy is required
