    The Earth's atmosphereis primarily composed of: 1. Nitrogen (N2) - 78% 2. Oxygen (O2) - 21% 3. Argon (Ar) - 0.93% 4. Carbon Dioxide (CO2) - 0.04% 5. Trace Gases (neon, helium, methane, krypton, hydrogen, and more) - < 0.1%

    The Earth's atmosphereis divided into five main layers: 1. Troposphere 2. Stratosphere 3. Mesosphere 4. Thermosphere 5. Exosphere

    The atmosphereserves several important functions: 1. Protects life on Earth by absorbing harmful solar radiation 2. Regulates the planet's temperature through the greenhouse effect 3. Supports weather patterns and the water cycle 4. Provides the air we breathe, containing the oxygen necessary for life

  2. Aircraft often fly in the lower stratosphere to escape the turbulence present in the troposphere. Near the top of the stratosphere lies the ozone layer. The mesosphere lies just above the stratosphere, ranging from about 30 to 50 miles above sea level. This layer contains chemicals which absorb energy from the sun.
