Water takes longer to boil at higher elevations because the atmospheric pressure is lower, which reduces the boiling point of the water. At higher elevations, there is less air pressing down on the water, so it needs to reach a higher temperature to boil.
At higher elevations, the atmospheric pressure is less. As you reduce the pressure, the temperature at which water boils is reduced. So, it will NOT take longer to boil, but will take shorter. It doesn't have to reach 212ºF at elevations, so it will boil at a lower temperature, which should take less time, unless, of course, you have a lot of wind or something else affecting the time to reach this lower temperature. In fact, the boiling point for water at 500 m above sea level is approximately 209ºF compared to 212ºF at home, depending on where home is.
At 1800 meters above sea level, the boiling point of water is around 93.5°C due to the lower atmospheric pressure.
Water boils at a lower temperature at higher elevations because the atmospheric pressure is lower. At higher elevations, the air is thinner, so there is less pressure pushing down on the water, causing it to boil at a lower temperature.
The temperature decreases the higher you go.
The pH level of salty water is between 7.36 and 8.21.
As you get higher above sea level, air pressure decreases. Water boils at a lower temperature when the air pressure is lower. When the water temperature is lower, pasta and anything else takes longer to cook.
The boiling point of any liquid is dependent upon the pressure of the atmosphere above the liquid therefore water boils at a lower temperature at higher altitudes. Because of this, the pasta takes longer to cook in the cooler boiling water.
Water evaporates faster at higher elevations compared to sea level because of the lower atmospheric pressure. This lower pressure allows water molecules to escape into the air more easily, increasing the rate of evaporation.
Water will boil at a lower temperature in a town located at 1000m above sea level, typically around 95°C instead of the standard 100°C at sea level. This is because atmospheric pressure decreases with higher elevations, causing water to boil at a lower temperature.
It takes longer to boil an egg above sea level because the atmospheric pressure decreases at higher altitudes, leading to lower boiling points. This means that the water will boil at a lower temperature, causing it to take longer to cook the egg.
At higher elevations, the atmospheric pressure is less. As you reduce the pressure, the temperature at which water boils is reduced. So, it will NOT take longer to boil, but will take shorter.

Water boils at a lower temperature at higher elevations because the atmospheric pressure is lower. At higher elevations, there is less air pressing down on the water, so it requires less energy to reach the boiling point.
You aren't at water level.
At higher elevations, air pressure is less. When air pressure is less, water boils at a lower temperature. That means food does not get as hot, so it takes longer to cook. Water at sea level boils at 212 degrees F. At my home in Colorado (7000 feet above sea level) water boils at 199 degrees F. At the top of Mt. Everest (29,029 ft) water would boil at 161 degrees F.
As of 02 JUL 2007 @ 0518 GMT, Lake Jim Chapman's water level was at 438.30 elevation above sea level. You can go to: http://www.swf-wc.usace.army.mil/reports/fish.htm and get all present lake elevations. It's difficult to get the level in feet of depth since the lake levels vary so, elevation above sea level is the method used by the corps of engineers. Don Zimmer

The temperature of boiling water at sea level is 100 degrees Celsius or 212 degrees Fahrenheit. At higher elevations, the boiling point of water is lower due to decreased atmospheric pressure.
