C13 The Earth's Atmosphere - Coggle Diagram
C13 The Earth's Atmosphere
Evidence of Early Atmosphere
The Earth's oceans
Rocks from Earth and other planets
Gases released during volcanic eruptions
Gases trapped in ice
Gases trapped in metiorites
Pollutants
Carbon particulates (soot)- global dimming and respiratory problems
Sulphur dioxide- acid rain
Carbon dioxide- global warming
Nitrogen oxides- acid rain and respiratory problems
Carbon monoxide- binds to haemoglobin and is often fatal
Effects of Climate Change
Changes in the amount and time of rainfall
Ice caps melting
Changes to ecosystems and habitats
Extreme weather events
Sea levels rising
The Greenhouse Effect
Some of the low frequency IR radiation is absorbed by greenhouse gases and re-emitted towards Earth in all directions
The radiation is absorbed by Earth, warming Earth's surface and re-emitted at a lower frequency
More greenhouse gases means more radiation is being emitted towards Earth than escaping to space
IR radiation of higher frequencies from the sun pass through Earth's atmosphere
This leads to an increase in Earth's average temperature (golbal warming)
Earth's Atmosphere
Argon- 1%
Oxygen- 21%
Nitrogen- 78%
Other gases- trace
Carbon dioxide- 0.04%
