Hi Crush- I'm curious what the book will be about. Meanwhile:
The
Earth's atmosphere has no definite top. The air just keeps getting
thinner as you go up. For each mile up you go, the density falls to
about 80% of what it was before. (That's why curveballs don't curve as
much in Denver as they do in cities at lower altitudes.)
