The composition of the atmosphere is changing today as it has been changing since the earth began to cool and atmosphere formed, just as the climate has gone through periods of heating and cooling. There have been multiple "ice ages", and multiple thawings. Ocean levels have gone up and down. Carbon dioxide has been absorbed by plants and buried for centuries, and carbon dioxide levels have gone back up following volcanic eruptions.
Lately, (in the last hundred years) the levels of carbon dioxide has gone up. Scientists believe that pollution from human activity is changing the atmosphere.
- Burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide (CO2).
- Bad agricultural practices emit methane (CH4), a powerful greenhouse gas.
- Deforestation has removed the trees that used to take carbon dioxide from the atmosphere.
What else can I help you with?
Why is earths composition of earths atmosphere important?
The Chemical Composition of the Earth's atmosphere is important because it holds the Earth together.
Which group of organisms is most responsible for changing the compisition of earths early atmosphere?
Cyanobacteria are the group of organisms most responsible for changing the composition of Earth's early atmosphere. Through photosynthesis, they released oxygen into the atmosphere, fundamentally altering its composition and paving the way for aerobic organisms to evolve.
Is the earths composition changing?
Yes, oxidation is changing materials and radiactive materials are changing.
How does the composition of Earths atmosphere different from the composition of the atmosphere of the gas giants planets?
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere

How do you use the word composition in a sentence referencing science?
Composition of the atmosphere is changing.
Earths early atmosphere was changed dramatically by the evolution of?
photosynthetic organisms, like cyanobacteria, which produced oxygen as a byproduct of photosynthesis. This led to the increase in atmospheric oxygen levels, changing the composition of Earth's early atmosphere.
