Graphing the atmosphere answer key – In the realm of atmospheric science, the task of graphing the atmosphere emerges as a crucial endeavor, unlocking the secrets of our planet’s gaseous envelope. This comprehensive guide delves into the intricate layers, temperature variations, composition, circulation patterns, and diverse phenomena that shape our atmosphere, providing a profound understanding of its dynamics and significance.
As we embark on this scientific journey, we will explore the complexities of atmospheric pressure, delve into the factors influencing temperature variations, and unravel the intricate composition of the air we breathe. Moreover, we will illuminate the patterns of atmospheric circulation, deciphering the mechanisms behind wind belts, jet streams, and global circulation cells.
Atmosphere Layers
The Earth’s atmosphere is a layer of gases surrounding the planet. It is divided into five main layers, each with distinct characteristics:
Troposphere
- Altitude: 0-10 km (0-6 miles)
- Temperature: Decreases with altitude
- Composition: 78% nitrogen, 21% oxygen, 1% other gases
Stratosphere
- Altitude: 10-50 km (6-31 miles)
- Temperature: Increases with altitude due to absorption of UV radiation by ozone
- Composition: 99% nitrogen, 1% oxygen, trace amounts of ozone
Mesosphere
- Altitude: 50-85 km (31-53 miles)
- Temperature: Decreases with altitude
- Composition: 85% nitrogen, 15% oxygen
Thermosphere
- Altitude: 85-600 km (53-373 miles)
- Temperature: Increases with altitude due to absorption of X-rays and gamma rays
- Composition: Mainly atomic oxygen and nitrogen
Exosphere
- Altitude: 600 km (373 miles) and beyond
- Temperature: Very high due to collisions with solar particles
- Composition: Extremely thin, mainly hydrogen and helium
Atmospheric Pressure: Graphing The Atmosphere Answer Key
Atmospheric pressure is the weight of the air above a given point. It decreases with altitude because there is less air above.
Atmospheric pressure is measured using a barometer. The standard atmospheric pressure at sea level is 1013.25 millibars (mb).
Relationship between Altitude and Atmospheric Pressure
The relationship between altitude and atmospheric pressure is inverse. As altitude increases, atmospheric pressure decreases. This is because there is less air above a given point at higher altitudes.
The graph below illustrates this relationship:

Temperature Variations
Temperature variations in the atmosphere are caused by several factors, including:
- Solar radiation
- Latitude
- Altitude
Temperature Ranges and Causes of Temperature Changes in Different Atmospheric Layers, Graphing the atmosphere answer key
| Layer | Temperature Range | Causes of Temperature Changes |
|---|---|---|
| Troposphere | -56.5°C to 15°C (-70°F to 59°F) | Solar radiation, latitude, altitude |
| Stratosphere | -56.5°C to 0°C (-70°F to 32°F) | Absorption of UV radiation by ozone |
| Mesosphere | 0°C to
|
Cooling due to expansion of air |
| Thermosphere | Absorption of X-rays and gamma rays |
Atmospheric Composition
The atmosphere is composed of a mixture of gases, including:
- Major gases: nitrogen (78%), oxygen (21%), argon (0.93%)
- Trace gases: carbon dioxide (0.04%), methane (0.00018%), ozone (0.000001%)

Atmospheric Circulation
Atmospheric circulation is the movement of air within the atmosphere. It is driven by differences in temperature and pressure.
Patterns of Atmospheric Circulation
The main patterns of atmospheric circulation include:
- Wind belts
- Jet streams
- Global circulation cells

Atmospheric Phenomena
Atmospheric phenomena are events that occur in the atmosphere. They include:
- Clouds
- Precipitation
- Storms
Cloud Formation and Precipitation
Clouds are formed when water vapor in the air condenses into tiny droplets or ice crystals. Precipitation occurs when these droplets or crystals become too heavy and fall to the ground.
Types of Precipitation
- Rain
- Snow
- Hail
- Sleet
Top FAQs
What is the significance of graphing the atmosphere?
Graphing the atmosphere provides a visual representation of atmospheric characteristics, enabling scientists to analyze and understand the complex interactions within our planet’s gaseous envelope.
How does atmospheric pressure vary with altitude?
Atmospheric pressure decreases exponentially with increasing altitude, as the weight of the overlying air column diminishes.
What factors influence temperature variations in the atmosphere?
Temperature variations in the atmosphere are influenced by factors such as solar radiation, latitude, altitude, and the presence of clouds and aerosols.
