It's absolutely self evident that no one ever taught you this. Similarly, no one ever taught you that the atmosphere has a top, i.e. that the atmosphere does not reach infinitely far out.
So yes, you are that ignorant.
... but it doesn't. The top of the atmosphere, where you will find earth's highest and lowest temperatures, has a much wider delta than at the bottom of the atmosphere, and you never learned this, because you never learned that the atmosphere has atmosphere. Did you ever go to school?
I'm still waiting for an answer. What component(s) of radiator fluid make(s) radiator fluid act as radiator fluid?
You need to follow instructions. Focus on the top of the atmosphere, which you now know exists because I just taught you, and explain how its wide temperature swings is a result of the atmosphere not having any atmosphere.
TOO FUNNY! I'm looking forward to your answer. Please don't forget to answer the "radiator fluid" question too.
