Layers of the Atmosphere
This is the lowest layer of the atmosphere where weather occurs.
Troposphere
The study of the atmosphere and the processes that cause weather
Meteorology
the most abundant gas in the atmosphere.
Nitrogen
The mass removal of trees causing increased carbon dioxide in the atmosphere
Deforestation
This atmospheric layer contains the ozone layer that absorbs harmful UV radiation.
Stratosphere
the thin layer of gases that surround Earth.
Atmosphere
The gas essential for respiration that makes up about 21% of the atmosphere.
Oxygen
Sources: industrial processes, vehicle emissions, agricultural activities, and burning of fossil fuels.
Air Pollution
Most meteors burn up in this layer of the atmosphere.
Mesosphere
In addition to the main elements found in the atmosphere, the atmosphere also contains various tiny solid and liquid particles called...
Particulates
This gas is present in small amounts but plays a major role in regulating Earth’s temperature.
Carbon Dioxide
Sources: burning fossil fuels
(coal, oil, natural gas),
livestock farming, landfills,
and industrial processes.
Greenhouse gas emissions
This layer has very thin air and is where the International Space Station orbits.
Thermosphere
the pressure exerted on a surface by the atmosphere; applied equally in all directions (up, down, sideways).
Atmospheric pressure
This variable gas is responsible for humidity and cloud formation.
Water Vapor
Human activities have increased
carbon dioxide levels,
contributing to
Global Warming
This outermost layer of Earth’s atmosphere gradually blends into outer space.
Exosphere
Meteorologists measure atmospheric pressure by using an instrument called a
Barometer
This group of gases, including argon and neon, makes up less than 1% of the atmosphere.
Trace gasses / noble gasses
This effect traps heat in the atmosphere and keeps Earth warm enough for life.
