Of the greenhouse gases, carbon dioxide (co 2) is the most prominent sources of atmospheric co 2 include volcanoes, the combustion and decay of organic matter, respiration by aerobic (oxygen-using) organisms, and the burning of fossil fuels, clearing of land, and production of cement by humans. Greenhouse gases are more complex than other gas molecules in the atmosphere, with a structure that can absorb heat they radiate the heat back to the earth's surface, to another greenhouse gas molecule, or out to space. A greenhouse is a house made of glass it has glass walls and a glass roof people grow tomatoes and flowers and other plants in them a greenhouse stays warm inside, even during winter sunlight shines in and warms the plants and air inside but the heat is trapped by the glass and can't escape so. The greenhouse effect, combined with increasing levels of greenhouse gases and the resulting global warming, is expected to have profound implications, according to the near-universal consensus of.
The greenhouse effect is a natural function of earth's atmosphere, the happy result of which is a livable world gases in the atmosphere, especially water vapor, insulate the earth, preventing the sun's heat from escaping. The table below shows the relative concentrations of these major greenhouse gases and their sources some gases (like co 2) are made by both natural and manmade processes, while others (like the fluorinated gases) are only the result of human industrial activity. Greenhouse gas definition, any of the gases whose absorption of solar radiation is responsible for the greenhouse effect, including carbon dioxide, methane, ozone, and the fluorocarbons.
A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range increasing greenhouse gas emissions cause the greenhouse effect the primary greenhouse gases in earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide and ozone. Greenhouse effect, a warming of earth's surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapour, carbon dioxide, methane, and certain other gases in the air. Manmade gas chlorofluorocarbons (cfcs) are the only greenhouse gases not created by nature other greenhouse gases, such as carbon dioxide, are emitted by human activity, but the molecules also occur naturally in the earth's atmosphere. The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.
Any of the gases whose absorption of solar radiation is responsible for the greenhouse effect, including carbon dioxide, methane, ozone, and the fluorocarbons any of the atmospheric gases that contribute to the greenhouse effect greenhouse gases include carbon dioxide, water vapor, methane, and. Water vapor the most abundant greenhouse gas, but importantly, it acts as a feedback to the climate water vapor increases as the earth's atmosphere warms, but so does the possibility of clouds and precipitation, making these some of the most important feedback mechanisms to the greenhouse effect. Other greenhouse gases are not counted in us or international greenhouse gas inventories: water vapor is the most abundant greenhouse gas, but most scientists believe that water vapor produced directly by human activity contributes very little to the amount of water vapor in the atmosphere.
Thanks to kurz gesagt for illustrating this video and for composing the music: thanks. Greenhouse gas definition is - any of various gaseous compounds (such as carbon dioxide or methane) that absorb infrared radiation, trap heat in the atmosphere, and contribute to the greenhouse effect.
Greenhouse gases absorb reflected solar energy, making the earth's atmosphere warmer a lot of the sun's energy reaches the ground directly, and a portion is reflected by the ground back into space some gases, when present in the atmosphere, absorb that reflected energy and redirect it back to. Each gas's effect on climate change depends on three main factors: how much of these gases are in the atmosphere concentration, or abundance, is the amount of a particular gas in the air larger emissions of greenhouse gases lead to higher concentrations in the atmosphere greenhouse gas.
The greenhouse effect often gets a bad rap because of its association with global warming, but the truth is we couldn't live without it life on earth depends on energy from the sun about 30 percent of the sunlight that beams toward earth is deflected by the outer atmosphere and scattered back into. The amount of greenhouse gases in our atmosphere is the highest it has been in the last 3 million years5 6 this is enhancing the greenhouse effect and making the earth warmer than normal, which is affecting the planet's weather patterns, creating global warming and climate change. The atmospheric gases and a greenhouse work in quite different ways, but the resulting effect, higher temperature in both cases, has led to the nomenclature greenhouse gases for the atmospheric gases responsible for the atmospheric warming effect. Greenhouse gases absorb this energy, thereby allowing less heat to escape back to space, and 'trapping' it in the lower atmosphere many greenhouse gases occur naturally in the atmosphere, such as carbon dioxide, methane, water vapor, and nitrous oxide, while others are synthetic.
