  • Layers of the Atmosphere - National Oceanic and Atmospheric Administration
    Exosphere This is the outermost layer of the atmosphere It extends from about 375 miles (600 km) to 6,200 miles (10,000 km) above the earth In this layer, atoms and molecules escape into space and satellites orbit the earth At the bottom of the exosphere is a transition layer called the thermopause Thermosphere Between about 53 miles (85 km) and 375 miles (600 km) lies the thermosphere

  • Earths Atmosphere Explained | Definition, Facts, Example, Quiz
    Earth's atmosphere is made up of a mixture of gases The two most abundant gases are nitrogen and oxygen, which together make up about 99% of clean, dry air The atmosphere also contains water vapor (humidity), which can be as much as 4% of the atmosphere in some places
  • 8. 3 Earth’s Atmosphere - Astronomy | OpenStax
    At Earth’s surface, the atmosphere consists of 78% nitrogen (N 2), 21% oxygen (O 2), and 1% argon (Ar), with traces of water vapor (H 2 O), carbon dioxide (CO 2), and other gases Variable amounts of dust particles and water droplets are also found suspended in the air
