as you move up from sea level, the atmospheric pressure decreases. At higher elevations, theres less air above you so therefor less air pressure. When the air pressure outside your body decreases, the air pressure inside also decreases (slowly).

How does atmospheric pressure change as you move away from the surface of earth?
Air pressure decreases as you move away from Earth's surface.
Where is atmospheric pressure maximum and why?
A saxophone is playing a steady note of frequency 210 Hz. The temperature in the room is 25 C. Suppose that, at some instant, the varying pressure at your eardrum is at a maximum. How far away (in meters) is the next pressure maximum? If anyone can help me with this, I would appreciate? The speed of sound at 25 C = 343m/s wavelength = speed of sound / frequency wavelength = 343m/s / 210/s = 1.6m Therefore, the distance of the next pressure maximum is 1.6m away from your ear drum.
How does the boiling point of a liquid vary with pressure?
Something boils when its vapor pressure equals the atmospheric (barometric) pressure above it. When the two are equal, that defines the boiling point.Therefore, you can either boil something by heating the liquid, and thus raising its vapor pressure (vapor pressure goes up with temperature), or you can boil something by reducing the atmospheric pressure above it until it matches the vapor pressure.See the Related Questions links to the left for more information about how the boiling point of water changes with elevation and atmospheric pressure.
Why does atmospheric pressure decrease as you rise above earths surface?
As you ascend higher in the Earth's atmosphere, the atmospheric pressure decreases due to several factors: Decreasing Density: The atmosphere is made up of gases held by the Earth's gravity. As you move higher, the density of the air decreases. Lower density means fewer gas molecules in a given volume, resulting in reduced pressure. Weight of the Air Column: Atmospheric pressure is the weight of the air above a given point. When you're closer to the Earth's surface, there's a thicker column of air above you, exerting greater pressure. As you ascend, the column of air above you decreases, leading to lower pressure. Gravitational Force: Gravity pulls gas molecules towards the Earth's surface. Near the surface, the weight of the air above compresses the air below, increasing pressure. As you move away from Earth's surface, the gravitational force weakens, allowing molecules to spread out more, leading to reduced pressure. Temperature Gradient: The temperature in the atmosphere varies with altitude. Generally, the troposphere (the lowest atmospheric layer) experiences a decrease in temperature with increasing altitude. Cooler air is denser, contributing to higher pressure at lower altitudes. These combined factors result in a decrease in atmospheric pressure with altitude. At sea level, the atmospheric pressure is higher due to the weight of the air column above. As you ascend, the fewer air molecules and reduced weight of the air column lead to lower atmospheric pressure. This decrease continues as you move higher into the atmosphere.
Do the winds move toward a high-pressure area or away from it?
Divergent
What happens to atmospheric pressure as you move up away from sea level?
As altitude above seal level increases, atmospheric pressure decreases.
How does atmospheric pressure change as you move away from the surface of earth?
Air pressure decreases as you move away from Earth's surface.
Does the atmospheric pressure increase or decrease as you move upward away from sea level?
The pressure will decrease, fall, as your altitude increases. No it would not it would increase above sea level
what are the dependent and independent variables of a ballon depending on atmospheric pressure?
The mass of the balloon is independent. Atmospheric pressure will not change this because atoms are not being added or taken away from the balloon itself or its contents. The volume of the balloon will change, however, as it will expand or compress in response to the atmospheric pressure around it. The volume, therefore, is a dependent variable in this situation.
The atmospheric pressure near the earths surface does what?
It decreases as you move away from the earth surface
Will the atmospheric pressure be more at the sea level or on a hill?
In general, on a hill. However, there are hills in places like Death Valley that are lower than sea level, so there are exceptions. This answer does not take other meteorological conditions into account. Barometric pressure at sea level in a hurricane can be much lower than on a hill miles away.
What happens to air pressure when you move upward away from sea level?
The farther up away you are from sea level the less air pressure there is.
Why do the boiling point of water decrease on climbing up the higher altitude?
Water usually boils at 212F or 100C at sea level. As you go higher up in the atmosphere (higher altitude), the amount of atmosphere pushing down on you decreases, hence the pressure decreases. Water boils when the vapor pressure of the water equals the atmospheric pressure. Vapor pressure increases with increasing temperature, so when there is less atmospheric pressure, a smaller vapor pressure is required to get the water boiling, hence a lower boiling temperature.

Is the pressure at the centre of a hurricane greater than or the same as or less than the pressure well away from the centre?
I just learned yesterday in lecture, that the center of a tornado is actually a deadly vacuum, relative to the atmosphere around it. Now, hurricane's are on a much larger scale, but the same mechanics should apply. The center of a hurricane will be lower than atmospheric pressure. (Atmospheric being 1 ATM, 101.3 kPa or 760 mmHg)
