You are right about what causes the meteorite to heat up, but the idea that it’s because of air friction is actually a very common misconception. I just wrote a post on my blog debunking what I consider to be the two most common misconceptions about air friction. Hopefully it is both correct and easy for anyone to understand.

Ah, so THAT’S the solution to global warming!

Antarctica is full of meteorites, and the tremendous chilling effect those meteorites have had on that continent is apparent.

This is the same concept that causes air compressor heads to get so hot, and the reverse of the effect that causes compressed air to chill when it is released.
CNN are idiots.

That left me scratching my head.
