Generally, atmospheric pressure is greatest at ground level, because you are at the bottom of the 25 mile thick atmosphere of earth. Greatest water pressure in a swimming pool is at the bottom, too. As you go up into the atmosphere, the pressure tends to decrease.
What else can I help you with?
How do you get the percentage of atmosphere above a height given in km and then how do you get the pressure for the height in mb?
To find the percentage of atmosphere above a certain height in kilometers, you can use the barometric formula to calculate the pressure at that height. Then, you can simply divide the pressure at the given height by the pressure at sea level (1013.25 mb) and multiply by 100 to get the percentage of atmosphere above that height.
A decrease in the height of a column in a mercury barometer means that?
there is a decrease in atmospheric pressure. Atmospheric pressure is directly proportional to the height of the mercury column in a barometer. When the height decreases, it indicates that the pressure in the atmosphere is lower.
At approximately what height in the atmosphere would the atmospheric pressure be at 1.0 millibars?
The atmospheric pressure of 1.0 millibars is typically found at an altitude of about 50 kilometers above the Earth's surface. At this height, the pressure is very low, and it is considered to be part of the upper atmosphere or exosphere.
How do you get the percentage of atmosphere above a height given in km and then how do you get the pressure for the height in mb What is the formula?
Formulas for atmospheric pressure variation with altitude. Scroll down to related links and look at "Atmospheric pressure - Wikipedia".
When the height of the mercury in a barometer is 29.92 inches the barometric pressure is?
When the height of the mercury in a barometer is 29.92 inches, the barometric pressure is equivalent to standard atmospheric pressure at sea level, which is 1013.25 millibars or 14.7 pounds per square inch (psi).
Weather element that always decreases with increasing height?
Pressure always decreases with height. This is because atmospheric pressure is just a measure of how much air is weighing down. So the higher you go in the atmosphere, the less air is above you (more of it is below you) and the lower the pressure will be.
How much is 1 atmosphere?
the atmosphere around us is troposphere in which we live and it is present upto 20km above earth..
Why atmospheric pressure varies with height in a different way from the way liquid pressure varies with depth.?
For the same reason. The liquid above the location considered, or the atmosphere above the position considered, helps contribute to the pressure; if there is more liquid or atmosphere above, there is more pressure.
Why air pressure decrease as you go higher in the earth's atmosphere?
As you move higher in the Earth's atmosphere, there are fewer air molecules above you exerting pressure downward. This leads to a decrease in air pressure with increasing altitude. The force of gravity still acts on the air molecules, but the density of the atmosphere decreases with height, resulting in lower pressure.
What causes classifying clouds to vary?
the shape and height causes it to vary with temperature,pressure,and the amount of water vapor in the atmosphere
What height in the atmosphere would atomospheric pressure be 1.0 millibars?
320,000 ft above sea leavel
What happens to the density of the atmosphere as height increases?
As height increases, the density of the atmosphere decreases. This is because there is less air above pushing down, leading to lower pressure and fewer air molecules per unit volume at higher altitudes.
