Methane, a greenhouse gas twenty times more dangerous than carbon dioxide, enters the atmosphere by way of:
There are many natural sources of methane and some man made. The man made sources include the drilling for, recovery of, processing of and use of fossil fuels.
The natural sources include:
Methane is a powerful greenhouse gas, twenty-one times stronger than carbon dioxide. It is being released into the atmosphere from:
As the earth warms, methane is beginning to escape from melting tundra and frozen lakes. This is a positive feedback, for the escaping methane will speed up global warming causing quicker melting. More global warming!
its entered by the tundra in n. east green land
Methane Gas is released in the air by the removal of Natural Gas from the grown.
In some locations from the world methane can be released naturally from the soil.
Methane gas settles down because methane gas is heavier than and is carried by the upward displacement of air. ---------------------------------------------- The density of methane is 0,717 g/L and the density of air is 1,2 g/L at 0 0C; consequently methane gas raise in the air.
The balanced chemical equation for the combustion of methane is CH4 + 2O2 -> CO2 + 2H2O. This means that the mole ratio of air to methane gas is 2:1, as two moles of oxygen from the air are required to react with one mole of methane gas.
Methane, krypton, and hydrogen make up only trace amounts in the Earth's atmosphere. Methane is around 0.0002%, krypton is about 0.0001%, and hydrogen is approximately 0.00005% of the air we breathe.
Yes, but it is very dangerous to the human body, in that high enough concentrations in the air can result result in suffocation.
Methane. It causes half of global warming and most methane gases come from cow farts.

Yes methane is lighter than air because it is less dense than air.
The fact that it oxidizes in air is a chemical property of methane.
The main reason is that oxygen is abundant in the atmosphere but methane is not. Air is 21% oxygen but only 0.00018% methane, so there is not enough methane in air to be of any use.
Flatulence contains a portion of methane gas, and the methane portion is lighter than air.

Believe it or not cars or factories are not the most air pollution. It is really Methane gas. Methane gas goes into the air actually when cows burp and pass gas.
