The troposphere is the lowest layer and contains about 75% of the mass of the atmosphere. The stratosphere contains about 20% of the mass of the atmosphere, the mesosphere contains about 5% of the mass of the atmosphere, and the thermosphere contains less than 1% of the mass of the atmosphere.<\/p>\n<p>The troposphere is where most of the weather occurs. The stratosphere is where the ozone layer is located. The mesosphere is where meteors burn up. The thermosphere is where the aurora borealis (northern lights) and aurora australis (southern lights) occur.<\/p>\n<p>The atmosphere gets thinner as you go higher in altitude.
