Why are gases like nitrogen and oxygen not greenhouse gases, despite being gases that exist in the atmosphere?
A. They occur naturally, so they cannot contribute to global warming
B. They exist in such large quantities that Earth is already used to them and is not affected by their activity
C. They are tightly bound, so they cannot vibrate and release radiation.
D. They are made of only one element, so they do not have the components necessary to be a greenhouse gas.
1. They are tightly bound, so they cannot vibrate and release radiation.
2. The molecule vibrates and releases infrared energy
3. No, this is incorrect because water vapor is a greenhouse gas and will increase the greenhouse effect.
4. The burning of fossil fuels causes both air pollution and water pollution
5. Chlorofluorocarbons
6. Sulfur dioxide and nitrous oxides
7. Initiating efforts to remove trash from oceans
8. nitrogen and phosphorus
9. an area in a waterway where no plants or animals live
10. Fewer microorganisms will grow on the surface of the lake
11. Using water and chemicals at high pressure to open up fissures to access oil and gas recourses
12. Climate change
13. The mines are operated adjacent to important waterways and are polluting them.
Thank you so much Samado!
Samado is 100% correct! tysm!
I love u samado
im in love with you samado
drbob you suck, if you dont have the answers and don't want to contribute to the conversation just dont reply
someone needs to svck samados toes

The correct answer is D. They are made of only one element, so they do not have the components necessary to be a greenhouse gas.
Greenhouse gases are those which have the ability to absorb and emit infrared radiation, trapping heat in the Earth's atmosphere and contributing to the greenhouse effect. While nitrogen (N2) and oxygen (O2) are indeed gases that exist in the atmosphere, they do not possess the molecular properties that allow them to act as greenhouse gases.
Both nitrogen and oxygen consist of diatomic molecules, meaning they are made up of two atoms of the same element - nitrogen and oxygen, respectively. These diatomic molecules have a symmetrical structure, which inhibits the necessary asymmetry for absorbing and emitting infrared radiation effectively.
Greenhouse gases, such as carbon dioxide (CO2), methane (CH4), and water vapor (H2O), consist of two or more different elements. This molecular composition creates vibration and rotation modes within the molecule, allowing them to absorb and emit infrared radiation, thus contributing to the greenhouse effect.
It is important to note that despite nitrogen and oxygen not being greenhouse gases themselves, they still play crucial roles in the Earth's atmosphere and climate system. Nitrogen makes up approximately 78% of our atmosphere, providing a stable environment for other atmospheric processes. Oxygen, on the other hand, is essential for respiration and supporting life on Earth.
