Why does a barometer have a higher reading at sea level then at the top of the mountain?

Air pressure on earth results from the earth's gravitational pull on the earth's atmosphere. In some sense, pressure results from the weight of the air above the point at which one measures pressure. At higher altitudes, there is less air above, resulting in less weight, which translates into pressure.

How can you get the sea level of a mountain?
yes you can get the even higher
Is atmospheric pressure higher on a mountain or sea level?
The answer is sea level. Because atmospheric pressure decreases when altitude increases
Is the altitude greater at the top of a mountain?
A mountain top is higher (greater) in altitude. That is the definition of altitude : height above a surface, or above sea level.
What would you use to measure the elevation above sea level on air temperature and air pressure?
elevation above sea level . . . barometer or GPS air temperature . . . thermometer air pressure . . . barometer
What is an ivory point in fortins barometer?
The ivory point in a Fortin barometer is a short (typically about 1 cm) conically-shaped piece of ivory positioned with its apex pointing vertically downwards just above the surface of the mercury in the barometer's reservoir. It is positioned accurately during manufacture so that the tip of the ivory is in exactly the same horizontal plane as the zero mark of the scale which measures the height of the mercury column, and is known as the Fiducial Point. Before reading the height of the mercury column, a user of the baromerter adjusts the level of mercury in the reservoir until its surface just touches the ivory point, at which level the height scale will give an accurate reading.
Is it possible to have a higher barometer reading at 1000 ft above sea level then you do at sea level?
When you have the same weather (high or low pressure region) then 1000 ft higher on top of a hill you will have lower barameter reading. On the hill there is not so much air over you. That's why there must be less pressure on you and on the barometer.
When climbing a mountain with a barometer will the mercury level decrease or increase?
decrease
Does a barometer stop measuring below sea level?
No, a standard barometer does not stop working at sea level.
How can you get the sea level of a mountain?
yes you can get the even higher
What is air pressure at Denver Colorado?
Air pressure is measured in different ways. Two common ones are PSI (pounds per square inch) or a barometer which measures in column inches of mercury. As we know the barometer goes up and down with weather so the air pressure goes up and down. The highest barometer reading ever recorded is about 32 inches or just over 15.6 PSI. The lowest barometer reading ever recorded was 25.69 in the middle of a hurricane so this is not typical but equates to about 12.5 PSI. These are all sea level readings. So we need an average, or normal. The standard is a barometer of 29.92 which equates to about 14.7 PSI, again being a sea level reading. With that standard the pressure at Denver is 12.1 PSI or a barometer of about 24.63. At this pressure water boils at about 202F instead of 212F.
Predict whether water would boil on top of a mountain at a higher or lower temperature than at sea level?
Water would boil higher at the top of a mountain than at sea level. This is because there is less atmospheric pressure at higher elevations.
Is atmospheric pressure higher on a mountain or sea level?
The answer is sea level. Because atmospheric pressure decreases when altitude increases
Are you allowed to read books that are not on the summer reading list but are on a higher or the same level?
You will need to ask the person who administrates your reading program.
A mountain 100 feet below sea level is near a valley 700 feet below sea level How many feet higher is the mountain then the valley?
600 feet if the mountain is already below sea level and so is the valley then just subtract the difference
What is actual pressure?
(meteorology) The atmospheric pressure at the level of the barometer (elevation of ivory point), as obtained from the observed reading after applying the necessary corrections for temperature, gravity, and instrumental errors. Source: Answers.com
Where the mercury barometer is used?
at sea level to messure air.
What mountains have the higher elevation the Rockies or the Appalachians?
The Rockies have higher elevations than the Appalachians. The highest peak in the Rockies, Mount Elbert, reaches over 14,000 feet, while the highest peak in the Appalachians, Mount Mitchell, reaches around 6,600 feet.
