Water boils at a lower temperature at a higher altitude.
You get closer to space.oh please be realthe higher you get the smaller the angle of the sun ray.the greater the angle the greater the heat
Your breathing can become laboured due to your smaller lung capacity in high altitudes.
because the higher u go, the less air is provided, no air pressure means things can't warm up in a wierd way,thus making things alot colder. For example, like up in the mountains.
The higher you go into the atmosphere the less particles are present, because of gravity, so you have less particles pressing against you (pressure).
