Air and the Atmosphere

  • The air in our atmosphere is essential to life.
  • Earth’s atmosphere enables life to exist on the planet.
  • Without it, there would be no water, no sounds, and it would be unbearably hot during the day and unimaginable cold at night.
  • This cloud of gas and solids extends thousand of miles from the Earth’s surface and is held in place by the Earth’s gravity.
