3. LAYERS OF ATMOSPHERE Earth atmosphere has a series of layers, each with its own specific traits. Moving upward from ground level, these layers are named the troposphere , stratosphere , mesosphere , thermosphere and exosphere . 3

4. TROPOSPHERE 4 1

5. The lowest part of the atmosphere - the part we live in. All weather occurs in this lowest layer. The temperature gets colder as the distance above the earth increases, by about 6.5°C per kilometer. TROPOSPHERE

6. STRATOSPHERE 6 2

7. 7 Air temperature increases with height due to sunlight absorption by ozone. As you go higher the temperature gets warmer. Little convection and turbulence Contains the ozone layer STRATOSPHERE

8. OZONE LAYER 8 3

9. 9 Is a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet radiation. Contains high concentrations of ozone molecules ( O 3 ). OZONE LAYER

10. MESOSPHERE 10 4

11. 11 The temperature decrease with height. The coldest layer of the atmosphere (-90 ). Meteors burn up in this layer.   MESOSPHERE

12. THERMOSPHERE 12 5

13. 13 High-energy, X-rays and UV radiation from the Sun are absorbed The hottest layer Temperature increases with altitude (over 2000°C) Aurora and satellites occur in this layer. THERMOSPHERE

14. EXOSPHERE 14 6

15. 15 The uppermost layer of our atmosphere. Is the atoms and molecules escape into space. composed of very widely dispersed particles of hydrogen and helium. EXOSPHERE
