why is it colder at higher elevations

652 views

This was asked by my 12 year old daughter while we were driving through the mountains the other day. It was 90° for several hours of our trip, then we reached the Blue Ridge mountains and the temperature dropped about 10 degrees. Seemed to happen once we reached about 2500 feet above sea level. I rather clumsily tried to give her an answer about air at higher altitudes being less dense, but quickly realized I didn’t have all the facts. Hoping someone can help me explain it better, so I can break it down better and explain it to my daughter.

Complicated question.

First it gets cooler down to 0′. Then it goes back up super hot in the ionosphere, before cooling back down again in space.
