Chemistry Atmosphere Revision
Gasses
Nitrogen - 80%
Oxygen - 20%
Argon - 0.93%
Carbon Dioxide - 0.04%
Early Atmosphere
Volcano activity 1st Billion years
Intense volcano activity.
The relreased gas (mainly CO2) that formed to early atmosphere and water vapour that condensed to form the ocean.
Other gasses
Released from volcanic eruptons.
Nitrogen was also released, gradually building up in the atmosphere . Small proportions of ammonia and methane also produced.
Reducing carbon dioxide in the atmosphere
When the oceans formed, carbon dioxide disollved into it.
This formed carbonate precipitants, forming sediments. This reduced carbon dioxide in the atmosphere.
Atmospheric pollutants from fuels
Combustion of fuels
Sourceof atmospheric polutants. Most fuels may also contain some sulfur.
Solid particles and unburned hydrocarbons released when burning fuels.
Carbon dioxide, water vapour, carbon monoxide, sulfur dioxide and oxides of nitrogen
Greenhouse gases
Carbon dioxide,water vapour and methane
Examples of greenhouse gasses that maintain temparatureson earth in ordeerto sustain life.
The Greenhouse effect
he greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere. Radiatively active gases (i.e., greenhouse gases) in a planet's atmosphere radiate energy in all directions.
