For example Jon Krakauer’s book Into Thin Air is about a deadly climbing expedition to Mount Everest. What does it mean to say the air gets “thinner” as you climb upward? Explain the reason why the air gets “thinner” with increasing altitude. Briefly explain why it becomes difficult to breathe in “thin” air. Your answer should include something about the human physiology of breathing and why it is more difficult when the air is "thinner."arrow_forward
