## How does atmospheric pressure change with the change in altitude?

Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.

## Why does atmospheric pressure depend on your location?

Atmospheric pressure depends on the altitude (or height) of your location. Many places on Earth are at sea level, which has an atmospheric pressure of 1 kilogram per square centimeter (14.7 pounds per square inch). The higher up we go, the less air pressure we will encounter.

## How does air pressure affect change in altitude class 7?

Atmospheric pressure decreases with increases in the altitude. Thus, the atmospheric pressure is high at lower altitudes, the density being higher. The atmospheric pressure is low at higher altitudes, the density being lower.

## Does atmospheric pressure increase or decrease as altitude increases neglect changes in temperature?

1 Answer. Atmospheric pressure decreases as altitude increases.

## How does temperature change as altitude increases?

As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases.

## How does temperature and pressure change with altitude in the atmosphere?

Thus the air temperature is highest near the surface and decreases as altitude increases. The speed of sound depends on the temperature and also decreases with increasing altitude. But there is always less air above us than was present at a lower altitude. Therefore, air pressure decreases as we increase altitude.

## Why the layers of atmosphere become thinner with altitude?

Long answer – The gravity causes the upper layers of atmosphere to exert force on the lower ones due to their weight. This causes the air to compress and hence the air become dense at the lower level(closer to surface) while in comparison the air at heights( far from surface) is rarer or thinner.
