Atmospheric pressure is the weight of the air above you. this weight is 14.7 lbs per square inch at sea level. Air is made up of 78% Nitrogen - 21% oxygen and 1% trace gasses at sea level, This changes as you ascend as oxygen thins out and other gasses take its place which are lighter than air this changes the partial pressures of the gasses and of cores the weight.

∙ 11y agoThe atmospheric pressure depends on various factors including the altitude from the sea level. In sea level, the atmospheric pressure is around 760 Hg mm. More informally, this value is also known as 1 atm.

∙ 10y agoat sea level it is about 14.7, i have looked around a bit and not been able to find anything more specific than that so hopefully that's enough for whatever youre trying to do

Does rain usually occur in high atmospheric pressure or low atmospheric pressure?
rain occurs in low atmospheric pressure.
Can mean effective pressure less than atmospheric pressure?
no Because any body subject is affected by the atmospheric pressure in the case of its occurrence under the pressure of what it means that the pressure for increased atmospheric pressure.
The force exerted by the weight of a column of air on a surface is called?
Air Pressure The force exerted by the air above is called?
Is barometric pressure the same as atmosheric pressure?
Yes, Barometric Pressure and Atmospheric Pressure are the same thing. Except one describes what Atmospheric Pressure would be measured in.
How are atmospheric pressure and water pressure different?
lalalal
What is a sentence with the word atmospheric pressure?
Atmospheric pressure
Does rain usually occur in high atmospheric pressure or low atmospheric pressure?
rain occurs in low atmospheric pressure.
How does the human body resist the atmospheric pressure?
because our body pressure is equal to the atmospheric pressure.
Can mean effective pressure less than atmospheric pressure?
no Because any body subject is affected by the atmospheric pressure in the case of its occurrence under the pressure of what it means that the pressure for increased atmospheric pressure.
What is the relation between pressure in atmosphere and pressure?
Atmospheric pressure is the surrounding pressure around us. We live in the atmosphere and treat the atmospheric pressure as the base pressure. A pressure gauge would read 0 at atmospheric pressure. When we define the pressure in scientific way of absolute pressure, we need to add up an atmospheric pressure to the measured pressure.
What is Neptune's atmospheric pressure compared to earth's atmospheric pressure?
42% higher
How does the atmospheric pressure at altitudes sea level compare with atmospheric pressure at sea level?
the atmospheric pressure below sea level is highter (novanet)
Is gauge pressure is the sum of true pressure and atmospheric pressure?
No, it is the DIFFERENCE between the true and atmospheric pressures.
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
Does Mars have extreme pressure?
The atmospheric pressure of Mars is 6 millibars as opposed to the 1,013 millibars of atmospheric pressure on Earth. Thus, its atmospheric pressure in relationship to Earth is extremely low.
What is the Significance of atmospheric pressure?
The atmospheric pressure plays a huge role when determining the weather. If the pressure is high, winds will be more active.
What atmospheric pressure causes hurricanes?
Hurricanes form from areas of low atmospheric pressure.
