Seismograph : Earthquake:: Barometer:?​

Answer 1

Answer:

Barometer : Atmospheric Pressure

Answer 2

Atmospheric pressure

Explanation:

• Barometer, a device can be designed to measure gas pressure. Because air pressure changes with distance above or below water level, a barometer may also be accustomed measure altitude. There are two main sorts of barometers: mercury and aneroid.
• In the barometer, gas pressure balances a column of mercury, the peak of which may be precisely measured. to extend their accuracy, mercury barometers are often corrected for ambient temperature and also the local value of gravity.
• Common pressure units include pounds per square inch; dynes per square centimetre; newtons per square measure (the SI unit called the pascal); inches, centimetres, or millimetres of mercury; and millibars gas pressure perplexed level is about 14.7 pounds per sq in, similar to 30 inches (760 millimetres) of mercury, 1,013.2 millibars, or 101,320 pascals.
• Of the numerous different sorts of mercury barometers, most variations arise from different techniques for measuring the peak of the mercury column. Though other liquids is employed in a barometer, mercury is that the most typical.
• If water were used, for example, the column would need to be 34 feet high. barometer, device to measure gas pressure.
