What is residence time of CO2?
Residence time of CO2 refers to the average amount of time a molecule of CO2 remains in the Earth's atmosphere before being removed by natural processes. It is estimated to be around 4 to 5 years.
What greenhouse gas stays in the atmosphere the longest?
Carbon dioxide, the most significant man-made greenhouse gas, is the most difficult to determine. Most of it is absorbed into the oceans, but that can take up to 200 years.Methane is more powerful than carbon dioxide, but methane breaks down after 12 years.Nitrous oxide remains in the atmosphere for more than 100 years.CFCs (chlorofluorocarbons) and similar gases (Compounds containing chlorine and/or fluorine (CFCs, HCFCs, HFCs, PFCs)) can remain in the atmosphere for many years. The IPCC has a list at this link.Water vapour remains in the atmosphere a very short time, from hours to at most several days, before it falls as some kind of precipitation.
Is climate related to atmosphere?
Yes, climate is related to the atmosphere as the atmosphere plays a key role in regulating Earth's climate. The composition of gases in the atmosphere, such as carbon dioxide and methane, contribute to the greenhouse effect, which influences the Earth's temperature and climate patterns. Variations in the atmosphere, such as changes in greenhouse gas concentrations or aerosol levels, can impact climate change.
What effect does the greenhouse effect have on light entering and leaving the atmosphere?
Greenhouse gases (water, carbon dioxide and methane, mostly) allow light to enter the earth's atmosphere. It comes in as solar radiation and about half of it is absorbed by the earth's surface. This radiation is converted to heat energy, which in turn, radiates infrared (longwave) radiation back out into space. Much of this infrared radiation is captured by the greenhouse gases in the troposphere (the lowest layer of the atmosphere). The warmed greenhouse gases then heat the air around them, and re-radiate the heat back down to earth, contributing to the greenhouse effect.
How far are greenhouse gases from the surface of the earth?
Greenhouse gasses are all around us. In fact, you breathe out carbon dioxide every time you exhale, and when you drink water, you're conusming H2O, which in vapor form is also a greenhouse gas.
Which has the longest residence time on continents?
Methane has the longest residence time on continents among the greenhouse gases, due to its lower reactivity and slower rate of removal from the atmosphere.
What is the residence time of water in the atmosphere?
The residence time of water in the atmosphere is around 9 days on average. This means that water molecules remain in the atmosphere for about 9 days before returning to Earth as precipitation.
If the total mass of N2 in the atmosphere is 3.87e21 grams or 2.901 moles based on the denitrification rate of 310e12 grams year what is the residence time of N2 in the atmosphere?
Residence time = 3.87E21/310E12 = 1.25E7 years
What is residence time of CO2?
Residence time of CO2 refers to the average amount of time a molecule of CO2 remains in the Earth's atmosphere before being removed by natural processes. It is estimated to be around 4 to 5 years.
How are greenhouse gases measured in the atmosphere?
Greenhouse gases in the atmosphere are measured using instruments like spectrometers and satellites that can detect and quantify the concentration of these gases in the air. Scientists collect data from various locations around the world to monitor and track changes in greenhouse gas levels over time.

What destroys greenhouse gases in the atmosphere?
Greenhouse gases are removed from the atmosphere through natural processes like photosynthesis in plants that absorb carbon dioxide, as well as through chemical reactions in the atmosphere that break down gases over time. Additionally, certain human activities, such as carbon capture and storage or reforestation efforts, can help reduce greenhouse gas levels in the atmosphere.
How did earths atmosphere change?
The Earth's atmosphere has changed over time due to various factors such as volcanic activity, changes in greenhouse gas concentrations, and natural variations in solar radiation. Human activities, such as the burning of fossil fuels and deforestation, have also significantly impacted the composition of the atmosphere, leading to an increase in greenhouse gas emissions and global warming.
How does the atmosphere trap heat on earth?
The Earth's atmosphere traps heat through a process called the greenhouse effect. Greenhouse gases in the atmosphere, such as carbon dioxide and water vapor, allow sunlight to pass through and warm the Earth's surface. When this heat radiates back towards space, the greenhouse gases trap some of it, preventing it from escaping and leading to an overall warming of the planet.
Is climate related to atmosphere?
Yes, climate is related to the atmosphere as the atmosphere plays a key role in regulating Earth's climate. The composition of gases in the atmosphere, such as carbon dioxide and methane, contribute to the greenhouse effect, which influences the Earth's temperature and climate patterns. Variations in the atmosphere, such as changes in greenhouse gas concentrations or aerosol levels, can impact climate change.
Do chemicals have the shortest average residence time in the biosphere lithosphere hydrosphere or atmosphere?
Chemicals generally have the shortest average residence time in the atmosphere. This is because they can be quickly dispersed or degraded by various atmospheric processes such as photolysis and chemical reactions. In comparison, chemicals may reside longer in the biosphere, hydrosphere, or lithosphere depending on their properties and interactions with the environment.
