Mostly water vapor, although there are trace gases such as carbon dioxide, methane and ozone that produce small additional amounts of warming.
A:The greenhouse effect has kept the planet warm for millions of years. When most people talk about the greenhouse effect now, they are referring to the enhanced greenhouse effect, which is being caused by additional carbon dioxide since man started burning fossil fuels about 200 years ago.Water Vapor is the gas that is largely responsible for the natural greenhouse effect that has warmed the earth for millions of years.Carbon dioxide is the gas that is largely responsible for the present accelerated greenhouse effect that is causing global warming.
Nitrogen is not considered a greenhouse gas because it does not absorb or emit infrared radiation, which is necessary for a gas to contribute to the greenhouse effect.
Gas
The gas that absorbs infrared radiation and contributes to the greenhouse effect is carbon dioxide (CO2).
It doesn't. Ozone is a greenhouse gas.
In terms of greenhouse effect, natural gas is more benign than coal or oil, because it provides a greater heating effect per unit of carbon dioxide produced. It is therefore not the major cause of the greenhouse effect.
Yes, ozone is considered a greenhouse gas because it traps heat in the Earth's atmosphere, contributing to the greenhouse effect.
Yes, ozone is considered a greenhouse gas because it traps heat in the Earth's atmosphere, contributing to the greenhouse effect.
Water (vapor).
The normal greenhouse effect which keeps the earth warm enough for life is caused largely by water vapour, with a small effect from carbon dioxide and methane.However, the greenhouse gas responsible for the present enhanced greenhouse effect is carbon dioxide, yes.
Gas and/or Atmosphere
Yes, gas is a noun. Greenhouse here is an adjective describing 'gas'. Together they make a noun phrase, 'Greenhouse gas'.
