You need to know the proportions of the main gases in the atmosphere.
The Earth's atmosphere has remained much the same for the past 200 million years. The pie chart shows the proportions of the main gases in the atmosphere.
It is clear that the main gas is nitrogen. Oxygen - the gas that allows animals and plants to respire, and fuels to burn - is the next most abundant gas. These two gases are both elements and account for about 99% of the gases in the atmosphere.
The remaining gases, such as carbon dioxide, water vapour and noble gases such as argon, are found in much smaller proportions.

The Earth’s
atmosphere has changed over billions of years, but for the past 200
million years it has been much as it is today. We are, however, causing
our atmosphere to change by human activity. Burning fossil fuels and deforestation are two examples of human effect on the environment.
