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.
What did the first barometer look like?
The first barometer was a mercury barometer invented by Evangelista Torricelli in 1643. It consisted of a glass tube filled with mercury inverted in a dish of mercury. As atmospheric pressure changed, the mercury level in the tube would rise or fall, allowing for the measurement of air pressure.
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.

What is a fall from a horse called?
A fall. Sudden dismount?
What is a sign that the weather may changing for the worse?
A sudden drop in the temperature
What does a bronometer look like?
A barometer typically consists of a sealed glass tube filled with mercury or an aneroid mechanism. In a mercury barometer, the tube is inverted in a reservoir of mercury, allowing the mercury level to rise or fall based on atmospheric pressure changes. An aneroid barometer uses a flexible metal diaphragm that expands or contracts with pressure changes, moving a needle on a dial to indicate the pressure level. Both types are often encased in decorative housing, making them suitable for display.
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.
What does a decrease in the height of the mercury column usually indicate on a barometer?
low pressure system and stormy weather

What kind of liquid is found in a barometer?
Mercury is the liquid typically found in a barometer. It is used to measure atmospheric pressure due to its density and ability to rise and fall within the tube as pressure changes.
What is a sudden brief fall off rain called?
floods
