Sign: ASK PROFESSOR SCIENCE
T-Rex: He didn't become a professor for complete strangers NOT to demand answers from him!

T-Rex: Our first question is from Marguerite!

T-Rex: Margie writes, "Dear Professor Science: if hot air rises, why is it cold at the top of mountains"?
T-Rex: Whoah. Margie is blowing this "science" thing wide open! Scientists LOVE to say that hot air rises, but you know how many people have frozen to death at the top of Mount Everest? NONE, obviously, because the mysterious "Everest Eliminator" pushes them off the top to their deaths, but it's still really cold there!

Utahraptor: I think it's because air is largely transparent!
T-Rex: Explain!

Utahraptor: Like light, the sun's heat mostly passes through the air, and instead warms up the PLANET! So the further up you go, the colder it gets, even though you are, TECHNICALLY, slightly closer to the sun.
T-Rex: Aha! FASCINATING.

T-Rex: Our next question comes from me, who writes "Dear Professor, I have not seen you in several years but still open your mail and answer it. Is our relationship healthy y/n".
T-Rex: And I believe the professor would say... YES, ABSOLUTELY??
