Objectives: SWBAT
• Compare/contrast he layers of the
atmosphere
• Understand that temperature changes or
various with altitude
• Temperature range and change is how
scientist label regions (layers of
atmosphere)
• Most life is contained in the troposphere

Activities:
• Warm-up
• Notes/discussion
• Atmosphere graph handout – students plot
and mark regions/patterns and locations of
important sections of the atmosphere

Layers of the Atmosphere
The Earth’s atmosphere has a distinctive
pattern of temperature changes with altitude
Scientist identify 4 main layers
![Page 5: Objectives: SWBAT€¦ · Objectives: SWBAT • Compare/contrast he layers of the atmosphere • Understand that temperature changes or various with altitude • Temperature range](https://reader034.fdocuments.net/reader034/viewer/2022042120/5e9a6c3bdbe60860813cf026/html5/thumbnails/5.jpg)
1.Troposphere – the lowest layer of the
atmosphere
• Temp. drops at a constant rate with as
altitude increases
• The part of the atmosphere where weather
conditions exist
• Almost all water vapor and CO2
![Page 6: Objectives: SWBAT€¦ · Objectives: SWBAT • Compare/contrast he layers of the atmosphere • Understand that temperature changes or various with altitude • Temperature range](https://reader034.fdocuments.net/reader034/viewer/2022042120/5e9a6c3bdbe60860813cf026/html5/thumbnails/6.jpg)
At an average altitude of 12km(7.5 miles)
the temp. stops decreasing –this region
called the tropopause
• Represents the upper boundary of the
troposphere
![Page 7: Objectives: SWBAT€¦ · Objectives: SWBAT • Compare/contrast he layers of the atmosphere • Understand that temperature changes or various with altitude • Temperature range](https://reader034.fdocuments.net/reader034/viewer/2022042120/5e9a6c3bdbe60860813cf026/html5/thumbnails/7.jpg)
2. Stratosphere – layer lies above the
tropopause
• Average altitude of 50 km
• Almost all ozone (O3) found in this region
• Temp. increases with altitude
• Air is heated by absorption of solar radiation
![Page 8: Objectives: SWBAT€¦ · Objectives: SWBAT • Compare/contrast he layers of the atmosphere • Understand that temperature changes or various with altitude • Temperature range](https://reader034.fdocuments.net/reader034/viewer/2022042120/5e9a6c3bdbe60860813cf026/html5/thumbnails/8.jpg)
The stratopause region 50 km (30miles)marks
the upper boundary to the stratosphere

3. Mesosphere - layer of atmosphere above
the stratopause
• Coldest layer
• Temp. decreases with altitude
• Extends up to 80 km up (50 miles)
• Meteors burn up/vaporize in this region
![Page 10: Objectives: SWBAT€¦ · Objectives: SWBAT • Compare/contrast he layers of the atmosphere • Understand that temperature changes or various with altitude • Temperature range](https://reader034.fdocuments.net/reader034/viewer/2022042120/5e9a6c3bdbe60860813cf026/html5/thumbnails/10.jpg)
• The mesopause is the upper boundary of the
mesosphere average temp. = -90ºC
![Page 11: Objectives: SWBAT€¦ · Objectives: SWBAT • Compare/contrast he layers of the atmosphere • Understand that temperature changes or various with altitude • Temperature range](https://reader034.fdocuments.net/reader034/viewer/2022042120/5e9a6c3bdbe60860813cf026/html5/thumbnails/11.jpg)
The Thermosphere is the uppermost layer of
the atmosphere
• Temperature increases tremendously with
altitude (hottest layer)
• 80 to 600 km altitude
• Very highly energized layer (solar wind) hits
causing upper auroras – northern lights
• Region known as the ionosphere is
contained in this zone – makes possible for
radio waves broadcast to bounce off and
travel great distance

ionosphere
![Page 13: Objectives: SWBAT€¦ · Objectives: SWBAT • Compare/contrast he layers of the atmosphere • Understand that temperature changes or various with altitude • Temperature range](https://reader034.fdocuments.net/reader034/viewer/2022042120/5e9a6c3bdbe60860813cf026/html5/thumbnails/13.jpg)
Exosphere • Above the thermosphere / ionosphere the
atmosphere blends into almost a complete
vacuum of space
• This region extends 1000 of kilometers
above the Earths surface (transition zone)
