Earth's atmosphere. Illustration showing layers of the Earth's atmosphere, as revealed by various natural phenomena. At lower left, weather occurs in the troposphere (below 15km height); passenger airlines fly to this ceiling. Above is the strato- sphere where the ozone layer (white line, balloon) occurs at 30-50km height. Meteor showers (lower centre) occur in the mesosphere to 80km; above in the thermosphere is the aurora effect at the level of the space shuttle. Electromagnetic radiation (right) penetrates levels of the atmosphere: gamma rays (centre right pale blue), X-rays, ultraviolet rays, a rainbow of visible light, infrared rays (orange) and radio waves (red).
