What gases exist today but were absent from early earth's atmosphere?
is it carbon dioxide
How does the present atmosphere differ from earth original atmosphere?
The original atmosphere contained only nitrogen, carbon monoxide, carbon dioxide, methane, and water vapor. Today's atmosphere contains 78% nitrogen, 21% oxygen, 1% shared between argon, carbon dioxide, helium, methane, ammonia, and neon.
Why is Earth's atmosphere rich in nitrogen and carbon dioxide today?
Nitrogen has, since plants and animals have existed, been the majority of gases in our atmosphere. Carbon Dioxide; however, has been increasing in our atmosphere since the industrial revolution. The causes are automobiles, coal-burning power plants and other carbon-emitting activities.
What gases make up the earths atmosphere today?
Nitrogen (78%), Oxygen (21%) and other (Carbon Dioxide, Argon: >1%)
Where are you most likely to find some of these gases like methane ammonia carbon dioxide sulfur and water vapor today?
I think its the atmosphere
How does the amount of carbon in the atmosphere today compare today to the amount in 1750?
it has almost doubled!
Why should the amount of carbon in the atmosphere today be reduced?
The present levels of carbon dioxide dioxide in the atmosphere are causing global warming and climate change.
How much carbon exist in the world today?
carbon exist in earth crust as 0.02% and in atmosphere 0.03%
What gases exist today but were absent from early earth's atmosphere?
is it carbon dioxide
How did the primitive atmosphere differ from atmosphere today?
As opposed to today's atmosphere, the Earth's early atmosphere would have been quite impossible for human life to thrive in. Today the atmosphere consists primarily of Nitrogen, Oxygen, and Carbon Dioxide, but early Earth's first atmosphere was probably made of Hydrogen and Helium.
How the did primitive atmosphere differ from your atmosphere today?
As opposed to today's atmosphere, the Earth's early atmosphere would have been quite impossible for human life to thrive in. Today the atmosphere consists primarily of Nitrogen, Oxygen, and Carbon Dioxide, but early Earth's first atmosphere was probably made of Hydrogen and Helium.

Why does burning these fuels and releasing the carbon back into the atmosphere create a problem today?
well, that is because of the lack of greenbelt today.

How are we changing the balance of the gases in our atmosphere today?
We are adding more and more carbon dioxide to the atmosphere. This is causing global warming and climate change.
Ice samples from glaciers provide evidence that today's atmosphere contains more carbon dioxide than ancient atmosphere on earth did.why id this increase in carbon dioxide a concern to scientists?
It is of no concern to scientists - its just data. However, it is a concern to the human beings who are also scientists since their environment is getting fouled up.
