The primary greenhouse gases are water vapour, carbon dioxide and methane. They are mixed throughout the atmosphere.
The greenhouse gases are carbon dioxide, nitrous oxide, methane, and water vapor.

∙ 6y agoThere are many gases which contribute to the greenhouse effect. Some are have a more potent effect than others. The following are considered to be greenhouse gases, the number after the name indicates the equivalent greenhouse gas effect compared to carbon dioxide (the principal man-made greenhouse gas):
- Water vapour (H2O) = ?
- Carbon dioxide (CO2) = 1
- Methane (CH4) = 21
- Nitrous oxide (N2O) = 298
- Sulfur Hexafluoride (SF6) = 22,200
- Chlorinated fluorocarbons (CFC's) = 1000 to 9000
Notes:
1. Water vapor is an odd one in the list as it is naturally occurring. It is responsible for more than 70% of the greenhouse effect
2. CFCs include many different compounds (all man created)
3. Carbon dioxide is the most common man made gas taking over more than 9% of the greenhouse effect. Man produces less then 7% of all CO2.
The forcing numbers for all significant green houses gases are as follows:
- water vapor 36-72%
- carbon dioxide 9-26%
- methane 4-9%
- ozone 3-7%
- Water vapour
- Carbon dioxide
- Chlorofluorocarbons
- Ozone

How has the earths atmosphere changed?
The earths atmosphere has significantly altered over the years. The process of the earth's atmosphere was recognized and evolved 2.7 billion years ago, forming the nitrogen-oxygen atmosphere that exists today. This change enabled the formation and beginning of the ozone layer (which along with magnetic fields) block solar radiation.
Why did the earth's atmosphere change after it was first formed?

Who is the inventor of the modern refrigerator?
carl von linde John Gorrie. His basic principle is often used in refrigeration today such as cooling caused by the rapid expansion of gases.
Assume that bacteria appeared on the meat in all three jars How would most scientists today explain this observation?
a.) Bacteria was present on the meat at the start of the experiment.
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.
What gases were present in earths today atmosphere?
Nitrogen
What is the importance of gases present in atmosphere?
Well the gasses help the atmosphere by protecting it also they are in your natural air today
Major gases of the atmosphere today are?
The major gases of the atmosphere are mainly nitrogen and oxygen. Nitrogen takes up 78.09% of the air and oxygen takes up 20.95% of the air. The rest is made up of 0.93% argon and 0.039% carbon dioxide.
What elements make up today's atmosphere?
gases, primarily nitrogen and oxygen
What gases exist today but were absent from early earth's atmosphere?
is it carbon dioxide
What are the main gases in the atmosphere of earth?
This is the approximate composition of the atmosphere today:78% Nitrogen21% Oxygen0.004% CO2The rest consists of Noble Gases, as well as traces of other various gases, like Ammonia and Carbon Monoxide.
What are the two gases that existed in earths earlier atmosphere?
The original atmosphere of earth contained primarily ammonia and methane, very similar to the atmosphere on Venus and Jupiter 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.
What is the major gas that is present today and long ago?
co2
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.
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
