Why are gases like nitrogen (N2) and oxygen (O2) not greenhouse gases, despite being gases that exist in the atmosphere?(1 point)
Responses
They exist in such large quantities that Earth is already used to them and is not affected by their activity.

They are made of only one element, so they do not have the components necessary to be a greenhouse gas.

When fossil fuels are burned, they emit carbon dioxide into the atmosphere. After centuries of large amounts of carbon dioxide accumulating in the atmosphere, the earth's temperature increases by 1°C.
What is the connection between increasing carbon dioxide and increasing temperature?
(1 point)
Responses
Carbon dioxide molecules that vibrate symmetrically cause heat to be emitted into the earth's atmosphere. This causes the temperature on earth to increase.
Carbon dioxide molecules that vibrate symmetrically cause heat to be emitted into the earth's atmosphere. This causes the temperature on earth to increase.
Carbon dioxide absorbs heat from the sun and traps it in earth's atmosphere. Since the heat cannot escape, it causes the earth's temperature to increase.
Carbon dioxide absorbs heat from the sun and traps it in earth's atmosphere. Since the heat cannot escape, it causes the earth's temperature to increase.
Carbon dioxide molecules do not affect the increase in earth's temperature because they vibrate asymmetrically. This means they cannot absorb heat.
Carbon dioxide molecules do not affect the increase in earth's temperature because they vibrate asymmetrically. This means they cannot absorb heat.
Carbon dioxide does not affect the increase in earth's temperature because it reflects radiation from the sun back into space.

Use the claim to answer the question.
“Heat from the sun is absorbed by greenhouse gases, which then vibrate and let off infrared energy. If we can block the heat from the sun, then the greenhouse effect will lessen because less heat will be absorbed, fewer molecules will vibrate, and less infrared energy will be released. In order to block the sun, we need to increase water vapor in the atmosphere, which will form clouds, blocking the sun’s rays.”
Is this line of thinking correct? Why or why not?

Responses
No, this is incorrect because water vapor is a greenhouse gas and will increase the greenhouse effect.
No, this is incorrect because water vapor is a greenhouse gas and will increase the greenhouse effect.
Yes, this is correct because the clouds will prevent lower layers of greenhouse gases from absorbing heat.
Yes, this is correct because the clouds will prevent lower layers of greenhouse gases from absorbing heat.
Yes, this is correct because the clouds will absorb the heat and not disperse it.
Yes, this is correct because the clouds will absorb the heat and not disperse it.
No, this is incorrect because the clouds will eventually move or break up.
