What is air ?
A mixture of different gases consisting of small molecules with large spaces between them
2 of 12
Percentage of main gases in the air ?
78% Nitrogen, 21% Oxygen, 1% Argon
3 of 12
What can affect air quality?
Other gases or particulates being released into the atmosphere by human activity or by natural processes e.g. volcanoes
4 of 12
How was the earth atmosphere formed and what did it contain ?
by volcanic activity and it consisted of mainly carbon dioxide and water vapour
5 of 12
What happened to to water vapour in the early atmosphere?
Water vapour condensed as the earth cooled to form oceans
6 of 12
What did the evolution of of photosynthesising organisms do?
It added oxygen to the atmosphere and removed carbon dioxide
7 of 12
How was carbon dioxide removed from the atmosphere ?
Carbon dioxide dissolved in the oceans
8 of 12
what happened after carbon dioxide was dissolved in the oceans ?
it formed into sedimentary rocks then later into fossil fuels
9 of 12
What elements have human activity added to the air ?
small amounts of carbon monoxide, nitrogen oxides, sulphur dioxides, extra carbon dioxide, small particulates of solid (e.g. carbon)
10 of 12
Who are pollutants harmful too?
they are directly harmful to humans and the environment (acid rain- sulphur dioxide)
