Parachutes work best in a dense medium. Since air density decreases with altitude, the closer you are to the surface the better a parachute will work. You still have to give it time to deploy to work, though.
Because - the further you are away from the Earth's surface - the lower the temperature is.
Above 100,000 feet altitude (20 miles).
Air pressure falls of as one gains altitude. At high altitude the air pressure is very low but it does not "falls drastically", which implies a sudden change.

At high altitude the temeperature is lower.
At high altitude the pressure is lower.
At a high altitude, water reaches its boiling point at a lower temperature because of a lower air pressure holding it in its liquid form.
high altitude
Lack of oxygen to the brain makes you dizzy. High altitude generally has lower density air, which gives you less oxygen in a given volume of breath than you would get with the same volume at a lower altitude.
At high altitude the pressure is lower and these factors favors evaporation.
Because of the lower pressure.
The atmospheric saturation of oxygen decreases as altitude increases. Almost all humans can't live above 18,000 feet due to low oxygen concentrations
A high altitude coffee maker is a special type of coffee maker that is used for areas that are at higher altitudes. What makes it different than standard coffee makers is that it boils water at a lower temperature due to the altitude.

High Altitude-Low Opening .My VersionOne of many is High Altitude Low Opening and refers to a special Parachute technique use to insert soldiers and spies covertly. The person jumps out of the Aircraft at 30,000 or 40,000 feet and then waits until the very last possible instant to open his parachute reducing the likely hood of being detected.
The boiling point temperature is lower at low pressure (altitude).
