1. LAYERS OF ATMOSPHERE

2. Introduction to the Atmosphere
 "The Earth's atmosphere is a complex system
of layers."

3. Overview of the Layers
 "Troposphere, Stratosphere, Mesosphere,
Thermosphere, Exosphere"

4. Percentage of Dry Air in earth’s
Atmosphere:

5. Troposphere:
 "The lowest layer where weather occurs.“
 “Temperature decreases with height.”
 “Boundary between the troposphere, and the
stratosphere is called theTropopause.”

6. Stratosphere:
 “Extends from 10 km to 50 km above the
ground.”
 “Temperature increases with altitude.”
 "Contains the ozone layer, which absorbs
harmful UV radiation.”

7. Mesosphere:
 “Extends to almost 80 km high”
 “Where temperature decreases with
altitude.”
 “Gases in this layer absorb very little UV
radiation.”

8. Thermosphere:
 “Above the mesosphere and extends to
almost 600 km high.”
 “Temperature increases with altitude”
 “Temperature can go as high as 1,500 °C.”

9. Exosphere:
 "Transition region to outer space.“
 “The interface between Earth and space.”
 “Atoms and molecules can escape to
space.”

10. Temperature variation with
height:

11. Importance of Understanding
Atmospheric Layers:
 "Critical for predicting weather patterns and
understanding climate change."

12. Application in aviation:
 Most light aircraft and turboprop aircraft fly
within the troposphere and this is where most
of the water vapour and
therefore cloud formation exists. Many types
of jet aircraft are able to cruise in the
Stratosphere, especially in high latitudes
where theTropopause is lower, thereby
avoiding almost all weather - although some
particular vigorous thunderstorms may
penetrate the stratosphere.
