Because pressure decreases as you go up in altitude and increases when you go down in altitude.
Hope this helped!
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.
Barometric pressure is generally lower near the ocean due to the influence of weather systems, such as low-pressure systems, that often form over large bodies of water. Additionally, the higher humidity levels near the ocean can also contribute to lower barometric pressure.
Barometric pressure at ground level refers to the atmospheric pressure at the Earth's surface. It is commonly measured in units of millibars or inches of mercury and can vary due to weather conditions, altitude, and geographic location. Changes in barometric pressure can indicate approaching weather systems and have effects on human health and behavior.
The change in pressure is highly affected by altitude.
As altitude increases, the rate of change of air pressure decreases. This is because the air becomes less dense at higher altitudes, leading to a more gradual decrease in pressure with increasing altitude.

A barometric pressure sensor is a type of sensor located within an engine system. It helps retain proper fuel mixtures at different altitude using barometric pressure measurements.
Radar altimeter gets altitude information by bouncing a radio wave off the surface of the Earth and determines the aircrafts altitude by measuring the length of time it takes for the signal to return. Barometric altimeters get altitude information by measuring the barometric air pressure outside the aircraft. Barometric pressure decreases as altitude increases. Radar altimeters will give altitude above ground level while barometric altimeters give altitude above sea level.
Barometric pressure is caused by the weight of the air pushing down on the Earth's surface. It is influenced by factors such as temperature, altitude, and weather patterns. Changes in barometric pressure can indicate changes in weather conditions.
It would be the barometric pressure of the atmosphere which depends on the altitude of the person in question.
To calculate altitude from pressure, you can use the barometric formula, which relates pressure to altitude. This formula takes into account the atmospheric pressure at sea level, the pressure at the given altitude, and the temperature of the air. By plugging in these values, you can determine the altitude based on the pressure reading.
At the altitude of 8,000 ft (2,438 m) the pressure is 1,572 pounds per square foot or 75 kilopascals.
The altimeter works by measuring minute changes in barometric pressure. Barometric pressure decreases as altitude increases, and altimeters are able to detect this change and use it to determine altitude. Barometric pressure is also effected by weather conditions, and so pilots must frequently adjusting the altimeter setting in order to compensate. Some new cessna 172's are being equipped with Garmin GPS cockpits which also get altitude information from GPS receivers, but these aircraft are also equipped with a standard altimeter in the interest of redundancy.
It's an airspeed indicator that compensates for outside temperature and barometric pressure at altitude.
The barometric pressure is what pilots use to gauge their altitude, however, all pilots above flight level 180 use 29.92. Barometric pressure is related to temperature changes, especially in higher altitude and mountainous areas.
Barometric pressure is generally lower near the ocean due to the influence of weather systems, such as low-pressure systems, that often form over large bodies of water. Additionally, the higher humidity levels near the ocean can also contribute to lower barometric pressure.
Increased altitude means decreased air pressure.
