Atmospheric pressure decreases with increasing altitude because the weight of the air above a given point decreases as you move higher in the atmosphere. At sea level, there is a greater column of air pressing down, resulting in higher pressure. As you ascend, there is less air above you, leading to lower pressure. Therefore, atmospheric pressure is greater at sea level compared to higher elevations.

What happens to atmospheric pressure as you move up away from sea level?
As altitude above seal level increases, atmospheric pressure decreases.
What planets air pressure is the same as it is 30 km above earths surface?
The planet with an atmospheric pressure similar to that 30 km above Earth's surface is Venus. At an altitude of about 50 km above Venus, the atmospheric pressure is comparable to Earth's surface pressure.
Why is the atmospheric pressure on moon is zero?
The atmospheric pressure on the moon is essentially zero because the moon does not have a significant atmosphere. Unlike Earth, which has a dense atmosphere that exerts pressure due to the weight of the air above us, the moon lacks this gaseous envelope and thus has almost no atmospheric pressure.
What is the relationship between atmospheric pressure and depth?
The deeper you go, the more air is above you ... thus higher air pressure.
Where would atmospheric pressure be greatest at sea level on a mountaintop at the altitude at which planes fly or at the outer edge of the atmosphere?
At sea level, atmospheric pressure would be greatest because of the weight of the entire column of air above that point. As you move higher up a mountain, atmospheric pressure decreases due to the lower column of air above. However, at the outer edge of the atmosphere, the pressure drops significantly as there is almost no air present in this region.
Why is atmospheric pressure greater at sea?
Atmospheric pressure is the weight of the air above the point... at sea level there is more air above the point then there would be at 10,000ft
How are density pressure and altitude related?
The higher you go, the lesser the air pressure becomes. This can be logically understood. Atmospheric air pressure is caused by the weight of the air above it. At greater heights, the amount of air above you is less, so there is less weight pressing on the air you are in. This is the reason why the atmospheric pressure is higher at the sea-levels and lower at mountains and places of high altitudes.
How does atmospheric pressure change with height above sea level?
Atmospheric pressure is the weight of the air above the surface of the earth. As elevation increases, there is less air above the location and the pressure is lower. At sea level the column of air above the area is greater.?æ
Is air density greater at the top or the bottom of a mountain?
Air density is greater at the bottom of a mountain due to the higher atmospheric pressure caused by the weight of the air above. As you move higher up the mountain, the air becomes less dense because the pressure decreases with altitude.
Why does atmospheric pressure increase with height?
Atmospheric pressure decreases with height due to the weight of the air above pushing down on the air below. As you move higher in the atmosphere, the air becomes less dense because there is less weight of air above it, leading to a decrease in pressure.
Does gauge pressure include atmospheric pressure?
Yes, gauge pressure includes atmospheric pressure. Gauge pressure is the pressure measured above atmospheric pressure, so it accounts for the atmospheric pressure as a reference point.
What does absolute pressure include that gauge pressure does not?
abosulute pressure includes the atmospheric pressure while gage pressure gives the pressure above atmospheric pressure
When intrapulmonary pressure is above atmospheric pressure what is able to occur?
When intrapulmonary pressure is above atmospheric pressure, air will move out of the lungs due to the pressure gradient, allowing for expiration. This is known as exhalation.
To measure a pressure above atmospheric pressure you would use?
A pressure gauge or manometer is typically used to measure pressure above atmospheric pressure. These devices can accurately measure the pressure difference between the system being measured and atmospheric pressure.
Why does atmospheric pressure decrease as you ascend in altitude on Earth?
As you go higher in altitude, the air becomes less dense, meaning there are fewer air molecules above you exerting pressure. This decrease in air density leads to a decrease in atmospheric pressure as you ascend in altitude on Earth.
What is the pressure above sea level in mmHg?
The atmospheric pressure at sea level is typically around 760 mmHg. As you increase in altitude above sea level, the atmospheric pressure decreases. For example, at 5,000 feet above sea level, the atmospheric pressure may be around 625 mmHg.
What happens the deeper you swim?
The deeper you swim, the greater pressure becomes because there is more water above you pressing down.
