Because as you climb higher there is less air above you pressing down on you with its weight.
1,700-foot decrease.
As altitude increases, barometric pressure decreases. This is because the air pressure decreases with increasing altitude, as there are fewer air molecules in the atmosphere exerting pressure on a given area.
The boiling point of water decrease when the altitude increase and the atmospheric pressure decrease.
Five ways:Temperature (increase in temperature means increase in pressure.)Velocity (increase the speed means decrease in pressure.)Amount of air particles (more particles means more pressure.)Changing the container (More space means less pressure.)Altitude (increase in altitude means decrease in pressure.)
As you decrease in altitude, the reading of a barometer will increase. This is because atmospheric pressure is higher at lower elevations due to the greater weight of the air above. Consequently, a barometer measures this increased pressure, resulting in a higher reading as you descend.

Air pressure.
As altitude increases, barometric pressure decreases. This is because the air pressure decreases with increasing altitude, as there are fewer air molecules in the atmosphere exerting pressure on a given area.
The boiling point of water decrease when the altitude increase and the atmospheric pressure decrease.
Altitude decreases, pressure increase, temperature decreases (some, but less effect than pressure), density goes up.
Temperature decreases with altitude in the mesosphere due to the decrease in atmospheric pressure with height. This is because the mesosphere is above the stratosphere where the ozone layer absorbs incoming solar radiation, leading to a decrease in temperature as altitude increases.

Decrease
In the troposphere, temperatures decrease with altitude (air pressure), in the effect known as the adiabatic lapse rate (9.8 °C per thousand feet).
Temperature decreases as altitude increases in the troposphere
No, atmospheric pressure decreases with altitude.
That's an effect of the increase and decrease in pressure which goes along with the altitude change.
