Persentase oksigen di udara di dua mil (3,2 km.) Pada dasarnya sama dengan di permukaan laut (21%). Namun, tekanan udara adalah 30% lebih rendah pada ketinggian yang lebih tinggi karena fakta bahwa atmosfer kurang padat - yaitu, molekul udara yang jauh apart.When kita menghirup udara di permukaan laut, tekanan atmosfer sekitar 14,7 pounds per square inch (1,04 kg. per cm.2)
