  1. Layers of the Atmosphere

  2. Layers • The four main layers are called the troposphere, the stratosphere, the mesosphere, and the thermosphere • The four main layers are classified according to temperature

  3. The Troposphere • The lowest layer of the Earth’s atmosphere (where we live) • Where the Earth’s weather occurs • 0-12 km in the atmosphere • About 1 km = 6.5 Celsius degrees cooler • At the tops of the troposhere it is about -60 degrees Celcius (-76 ⁰F)

  4. The Stratosphere • 12-50 km in atmosphere • Upper stratosphere is warmer than lower stratosphere because it contains a layer of ozone • Ozone absorbs energy from sun and converts to heat

  5. The Mesosphere • 50-80 km in atmosphere • As altitude increase, temperature decreases (upper mesosphere is -90 ⁰C or -130⁰F) • This is where you see shooting stars (mesosphere protects Earth from being hit) • Little change to environment

  6. The Thermosphere • No define outer limit- runs into outer space • As altitude increases, temperature increases to 1800 degrees Celsius (3272 ⁰F) • Why is the thermosphere so hot? • Energy coming from sun strikes thermosphere first. • Little change to environment
