My son, who is in Primary 4 (4th grade in the US?) asked me this question recently. For once, me, the acknowledged "know-it-all" in the family, was at a loss.
Tried searching for this on the internet, no luck.
I suspect it's got something to do with the air density (it gets less the higher you go). But *why* does it get colder the higher up you go?
