Does a mercury barometer or aneroid barometer measure air pressure?
mercury has a sudden fall and then the barometter measure it and when i mean by fall i mean air pressure so yeah it's cool I knoe it doesn't make sense but Im just writing this anyway. Even though it's pure glorius silly you know what. I PUT THAT WORD BUT THEY WON'T LET ME POST THIS STUPID ANSWER
Why does a barometer fall before it rains?
Air pressure is the weight of the air around us. When there is a period of low pressure, a barometer detects this and displays it with the needle. This reading is showing the weight of the air. It normally rains during a period of low pressure, so if the needle on the barometer is pointing to low pressure or rain, you can predict what the weather will be like in the following days. Hope this answers your question.
If the barrometer rises does the temperature rise?
The precipitation does NOT cause the rise or fall in the barometer. However precipitation is more usually associated with an atmospheric depression (a cyclone) and thus a fall in the barometer will usually FORETELL precipitation.
How to Predict the Weather Using a Barometer?
Of all weather instruments essential to forecasting, the barometer tops the list. Why? Because every weather change is preceded by a rise or fall in air pressure, and air pressure is just what the barometer measures. If you compare two barometer readings taken an hour or two apart, you will know immediately if the air pressure is rising, falling, or staying the same. And as a result you will be able, with a fair amount of accuracy, to predict tomorrow’s weather. RISING BAROMETER: When the air pressure measures higher than it did in your previous reading, the air is becoming denser, and the barometer is said to be rising. This tells you that clearer, drier, cooler weather is on the way. If the barometer is rising very rapidly from a low position, the weather will clear up very soon, and it will probably become quite windy. But if the barometer rises from a low position gradually and steadily, a long period of good weather is just around the corner. If the barometer is already high and suddenly starts to rise rapidly, expect a sudden drop to follow shortly, and with it, bad weather to come. FALLING BAROMETER: A falling barometer usually indicates rain, wind, and warmer weather. Take note of the speed at which the barometer falls. A very large and rapid drop in air pressure is a sure sign of an approaching storm. If the barometer falls suddenly, but not too far, expect wind and brief showers. If the barometer falls slowly and steadily to a moderately-low position, it may rain nearby, but not necessarily in your immediate area. UNCHANGING BAROMETRIC PRESSURE is a pretty good indication that whatever weather you’re currently enjoying is not about to change any time soon. IMPRESS YOUR FRIENDS AND NEIGHBORS! With a little experience in charting barometric pressure in your area, you will soon become skilled at noting any changes which are out of the ordinary. At this point, your weather-predicting abilities may begin to rival those of your local TV weatherman. And that would be something to brag about!
What causes the earths crust to rise and fall?
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
What will hot air do to a barometer?
The air will become lighter causing the barometer to fall. the opposite will occur for cold air.

When a spring balance holding a mass is allowed to fall freely what reading will it show?
It will have a 'finger' pointer against a scale to indicate mass.

What is a fall from a horse called?
A fall. Sudden dismount?
How the barometer is used?
A barometer is advice used to atmospheric pressure. They are commonly contain water, air, or mercury. The medium used raises and falls in a tube with a reservoir at the base. The pressure from the outside air pushes on the medium in the exposed reservoir. This push is what causes the medium raise or fall. The measure of the barometer can indicate local weather patterns. High pressure indicates fair weather, while low pressure indicates a storm.
If the barrometer rises does the temperature rise?
The precipitation does NOT cause the rise or fall in the barometer. However precipitation is more usually associated with an atmospheric depression (a cyclone) and thus a fall in the barometer will usually FORETELL precipitation.
What does a decrease in the height of the mercury column usually indicate on a barometer?
low pressure system and stormy weather
What is a sign that the weather may changing for the worse?
A sudden drop in the temperature
What does downfall mean?
a sudden fall of rain or snow
If Torricelli had drilled a little hole at the top of a glass tube holding his mercury column what would have happened to his barometer?
He would not have had a barometer. He would have had a glass tube stuck into a bowl of Mercury, with nothing in it. Because once the hole was made the vacuum would be gone and the mercury would fall back down to the bowl.It takes the vacuum in the tube to create a barometer.
