What is the humidity level usually observed at high altitudes?

• A. 30%
• B. 50%
• C. Less than 1%
• D. 10%

Answer: (C)

At high altitudes, the humidity level is typically very low, often less than 1%. This is primarily due to the decrease in atmospheric pressure and temperature as altitude increases, which leads to the capacity of air to hold moisture diminishing. Consequently, the air becomes much drier, impacting the body’s ability to maintain hydration and can lead to conditions such as altitude sickness. High altitude environments are characterized by their arid conditions, which is why the correct answer reflects the extreme reduction in humidity levels compared to those observed at sea level or in more temperate zones.
