What is meant by the term greenhouse effect listing the three most significant greenhouse gases?
The term "greenhouse effect" is made up of two different effects: "Natural and Man-made". There is a "natural" greenhouse effect that keeps the Earth's climate warm and habitable. There is also the "man-made" greenhouse effect, which is the enhancement of Earth's natural greenhouse effect by the addition of greenhouse gases from the burning of fossil fuels (mainly petroleum, coal, and natural gas). The three most significant green houses gases and the amount they contribute are water vapor (80%), carbon dioxide (6%) and methane (1%). Nature produces 99.7% of all green house gas emissions.
How many greenhouse gases are there?
There 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 principle man made greenhouse gas:Water vapour (H2O) = ?Carbon dioxide (CO2) = 1Methane (CH4) = 21Nitrous oxide (N2O) = 298Sulfur Hexafluoride (SF6) = 22,200Chlorinated fluorocarbons (CFC's) = 1000 to 9000Notes:1. Water vapor is an odd one in the list as it is naturally occurring. It may be responsible for more than 30% of the greenhouse effect2. CFC's include many different compounds.
What is a greenhouse gas that exclusively anthropogenic?
CFCs (chlorofluorocarbons) are greenhouse gases that are entirely made by human endeavors. All other greenhouse gases (carbon dioxide (CO2), methane CH4, etc occur in nature as well as being produced by man.
The greenhouse effect is due largely to what?
It is caused by humans emitting harmful gases and chemicals into our Earth's atmosphere.Further information:Earth has both a "natural" greenhouse effect and a "man-made" greenhouse effect.The natural greenhouse effect is caused mostly by water vapour, and to a much smaller degree, to carbon dioxide, methane, and a few other minor gases. These factors help keep the Earth warm and habitable.The "unnatural" greenhouse effect is what results from the burning of fossil fuels and rainforest trees, which release extra carbon when they are felled and burnt.
What is the artificial greenhouse effect?
If you mean the man-made one, it is the accelerated, or enhanced greenhouse effect, caused by man's burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide. Carbon dioxide is a greenhouse gas which is causing global warming and climate change.
Is the fallowing sentence true or false the greenhouse effect is a natural process?
The greenhouse gases present in the earths atmosphere are both naturally produced and man made. The natural greenhouse gases (methane, water vapour, carbon dioxide) make the Earth warmer than it would be without the Greenhouse effect (this allows it to be habitable). The addition of man made greenhouse gases (methane, carbon dioxide and a few others) increases the temperature past the natural levels. SO the greenhouse effect is both natural and a result of human activities. If you consider the opposite of a "natural effect" to be a "supernatural effect" resulting from gods, devils or ghosts -the greenhouse effect is natural with no supernatural contribution.
The greenhouse effect is caused by the warming of?
The planet(s) through solar radiation and the retention of a small portion of this heat through atmospheric gases. The greenhouse effect is caused by the warming of the greenhouse gases in the atmosphere, mostly water vapor and carbon dioxide. This is a natural effect that has gone on for millions of years. The enhanced greenhouse effect, what we are experiencing now, is caused by the warming of the extra greenhouse gases that man is adding to the atmosphere, largely by burning fossil fuels, and by deforestation.

Is global climate change man-made?
Yes it is. It's a by-product of burning fossil fuels, which release greenhouse gases, including Carbon Dioxide. It is also a side effect of deforestation and intensive livestock farming, which releases methane. In effect, our presence has resulted in a change in balance between the removal of greenhouse gases from the atmospehere and the production of greenhouse gases.

What are the artificial green house gases?
CFCs (chlorofluorocarbons) are man-made gases that are also greenhouse gases.
Is the greenhouse effect really responsible for global warming?
Yes, the greenhouse effect is a natural phenomenon which has existed here for trillions of years and protected the earth from global freezing like the ice age. But increases in greenhouse gases mostly carbon dioxide caused by man's burning of fossil fuels is causing an enhanced, or accelerated greenhouse effect which is responsible for global warming.
Are greenhouse gases affecting the earth?
At present man-made greenhouse gases, carbon dioxide (CO2) and methane, are adding to the greenhouse effect. The natural carbon cycle is unable to cope with the extra CO2 which remains in the atmosphere gathering heat, and causing global warming. Less than 1% of the gases in Earth's atmosphere are called greenhouse gases. Even though they are not very abundant, these greenhouse gases have a major effect. Carbon dioxide (CO2), water vapor (H2O), methane (CH4), nitrous oxide (N2O), and a few other gases are greenhouse gases. They all are molecules composed of three or more atoms, bound loosely enough together to be able to vibrate when they absorb heat. Eventually, the vibrating molecule will emit the radiation again, and it will likely be absorbed by yet another greenhouse gas molecule. This process is called the greenhouse effect and keeps heat near the Earth's surface. All of the green house gases that are mentioned in the above answer are not necessarily man made. They are all natural gases in our environment. The jury is still out on whether we make enough to cause severe climate change as is claimed.
What greenhouse gases are man-made?
Carbon dioxide exists naturally in the atmosphere as a result of the earth's carbon cycle. It is also there as a result of man's activities in burning fossil fuels (coal, oil and natural gas), which releases long-stored carbon dioxide to add to the greenhouse gases already there.Methane occurs naturally in the atmosphere, but is also produced by man's cattle ranching.Nitrous Oxide (310 times more powerful than CO2) is emitted from industry, rocket and vehicle engines and even aerosols.CFCs (chlorofluorocarbons) are completely made by man. They were released for a while from aerosols and are now being phased out as a refrigerant.
Where greenhouse occurs what it is the origin?
There have always been greenhouse gases keeping the planet comfortable for life. They are part of the water cycle and the carbon cycle. Greenhouse gases hold back some of the sun's heat to keep the planet from freezing.The greenhouse effect that scientists are worried about now is the enhanced, or accelerated greenhouse effect, which has been warming the planet steadily for the last 200 years, since man started burning fossil fuels (coal, oil and natural gas). Burning these releases extra carbon dioxide that has been stored away for millions of years in the coal and oil. This extra carbon dioxide is causing the present greenhouse effect.
