How does earths rotation help to maintain its temperature? Please help!!!

Earth returns an equal amount of energy back to space by reflecting some incoming light and by radiating heat (thermal infrared energy). Earth's average surface temperature is maintained by two large, opposing energy fluxes between the atmosphere and the ground (right)—the greenhouse effect.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

i might be wrong but i think its a. let me know if i’m right and have a good rest of your day!
