Question

question 9 of 10
what would be the most likely result if humans stopped burning fossil fuels?
a. the greenhouse effect would become stronger.
b. global warming would be decreased.
c. there would be more carbon dioxide in the atmosphere.
d. there would be less oxygen in the atmosphere.

Explanation:

Burning fossil fuels releases carbon dioxide (a greenhouse gas). Greenhouse gases trap heat, contributing to global warming. Stopping burning fossil fuels would reduce carbon dioxide emissions. Less carbon dioxide means less heat is trapped, so global warming would decrease.

• Option A: Less carbon dioxide (from stopping fossil - fuel burning) would weaken the greenhouse effect, not strengthen it.
• Option C: Stopping fossil - fuel burning reduces carbon dioxide emissions, so there would be less carbon dioxide in the atmosphere, not more.
• Option D: Burning fossil fuels does not consume oxygen in a way that would significantly reduce atmospheric oxygen levels compared to other natural processes (like photosynthesis which produces oxygen).

Answer:

B. Global warming would be decreased.
