Answer:

Because of lower atmospheric pressure.

Explanation:

  • As the elevation increases the atmospheric pressure decreases.

  • At sea level the pressure is at 1 #atm# and as you go up that number goes down.

  • This is why a humans blood would boil in the vacuum of space, because there is no pressure. The vapor pressure of the blood would be equal to the atmospheric pressure and boiling would ensue.
