Why do people find it difficult to breathe at higher altitudes?
Asked by Aryan Srivastava | 13th Nov, 2014, 07:20: PM
Air is a mixture of several gases. It consists of a number of gases including oxygen, nitrogen, carbon dioxide, rare gases etc. As we go up, the air column decreases.The density of air layers is more near the earth surface and is less at higher altitudes,that means less oxygen is available for breething and this makes breathing difficult at higher altitudes.Hence mountaineers carry oxygen cylinders due to the deficiency of oxygen in higher altitudes.
