Question

Which of the following best describes a way in which human activities affect the level of greenhouse gases in the atmosphere?

Using aerosol sprays increases the amount of ozone (O3) in the atmosphere.

Burning fossil fuels decreases the amount of water vapor (H2O) in the atmosphere.

Deforestation increases the amount of carbon dioxide (CO2) in the atmosphere.

Using appliances that absorb radiation decreases the amount of chlorofluorocarbons (CFCs) in the atmosphere.

Answer 1

Ok... to start with... which of those are greenhouse gases? Are there any answers that you can cross out right away?

Answer 2

I Was Thinking Of Crossing Out C & A ?

Answer 3

Can you explain why?

Answer 4

Well... See I Am Not Good At Biology AT ALL ! & They Just Don't Really Make Since To Me .

Answer 5

This is more of an environment-related question, actually. And I don't think A sounds quite right either: as far as I know, aerosol sprays (at least those that contain CFCs) are more likely to deplete the ozone layer. CFCs can be greenhouse gases themselves, I believe, but I don't see any answer that alludes to their role.

I want you to look at number C again, though. Why don't you think it makes sense?

Answer 6

Er... not number C. Just C. I know C is not a number.

Answer 7

Well, It Is Just Idk .... I Told You I Am REALLY Bad ! Biology Is like ONE Of The Subjects I Dont Understand AT ALL !

Answer 8

Well... you know how we breathe in oxygen and breathe out carbon dioxide? Plants do the opposite. They taken in carbon dioxide and "breathe out" oxygen. ALL the oxygen that you're breathing right now was produced by plants! Carbon dioxide is a greenhouse gas. So... if there are fewer plants taking it in and turning it into oxygen, what will happen?

Answer 9

I Got The Answer. My Mom Actually Came Over Here & Helped. She Said C ...... :/

Answer 10

Just make sure you understand WHY it's C :) If you can understand why the correct answer is correct, you'll have a much easier time on your next homework assignment or on a test.

Answer 11

This Was A Test. I Have FVS & Its Hard. I Have to Go To hs & Then I Also Have To Do On Computer :/

Answer 12

i got FLVS too, and Im doin this assignment. C is correct, but my answer choices doesnt have that, so i choose burning fossil fuels (this is for other students with this answer suggestion).
