Ignoring the variations in moving air masses, atmospheric pressure decreases steadily with altitude. A higher altitude will always have a lower air pressure, becoming virtually zero (less than 1 kPa) at around 33 kilometers of altitude, or 108,000 feet above MSL. There are still enough molecules in the thermosphere to cause atmospheric drag on satellites in Low Earth Orbit, up to about 500 km (310 miles).

What happens to density at higher altitudes?
The density of air decreases at higher altitudes.
Why one of the windows in the Flying At High Altitudes Breaks?
as their is high pressure inside and low pressure outside and air moves
How does atmospheric pressure vary with elevation?
Atmospheric pressure decreases with increasing elevation due to the thinning of the air as altitude rises. At higher elevations, there is less air above to exert pressure, resulting in lower atmospheric pressure. This decrease in pressure is not linear; it drops more quickly at lower altitudes and gradually levels off at higher altitudes. As a result, climbers and those at high altitudes often experience reduced oxygen availability due to the lower pressure.
Is air molecules closer together at higher altitudes?
No, air molecules are not closer together at higher altitudes; they are actually farther apart. As altitude increases, the atmospheric pressure decreases, leading to a lower density of air molecules. This means that there are fewer air molecules in a given volume compared to lower altitudes. Thus, air becomes thinner with increasing elevation.
Why do a fountain pen starts leaking at higher altitudes?
A fountain pen might leak at higher altitudes due to changes in air pressure. As the altitude increases, the air pressure decreases, causing the ink inside the pen to flow more easily or even leak out. This can result in messy ink spills.
Which altitudes would have the lowest air pressure and why?
The highest altitudes have the lowest air pressure. Air pressure increases as altitude decreases. Above sea level is lower pressure; below sea level is higher pressure.
Is air pressure higher at higher altitudes?
Yes, air pressure is lower at higher altitudes.
What does air pressure do as altitudes?
Air pressure increases as altitude decreases.
Why is it colder at higher altitudes?
At higher altitudes, the air pressure decreases, causing the air molecules to spread out and the temperature to drop. This is why it is colder at higher altitudes.
Is air pressure greater at high altitudes or low altitudes?
It is greater at a lower altitude.
What time of day is air pressure the lowest?
The density of air is lowest in the summer, because warmer air is less dense. (the molecules are in greater motion, and are forced farther apart)
Why the pressure of oxygen becomes low at high altitudes?
At higher altitudes, the air pressure decreases because the air molecules are more spread out. This reduction in pressure means there are fewer oxygen molecules available in the air to be breathed in, leading to lower oxygen levels at high altitudes.
What happens to density at higher altitudes?
The density of air decreases at higher altitudes.
Is air pressure the same at high altitudes?
No, it is not. The pressure decreases as the altitude increases.
At which altitude is air pressure lowest?
The air pressure is lowest at the highest altitudes, such as at the top of Mount Everest or in the upper layers of the atmosphere. This is because as altitude increases, there are fewer air molecules above exerting pressure downward.
Where in a diagram would the air pressure be the greatest?
In a diagram depicting air pressure, the air pressure is typically greatest at the bottom of the diagram. This is because air pressure increases with depth in the atmosphere due to the weight of the air above compressing the air below. Consequently, areas at lower altitudes or depths will exhibit higher air pressure compared to those at higher altitudes.
What cities have the lowest air pressure?
Cities located at high altitudes tend to have lower air pressure, such as La Paz in Bolivia, Lhasa in Tibet, and El Alto also in Bolivia. These cities are situated well above sea level, which results in lower air pressure compared to cities at sea level.
