Question

When the atmospheric pressure of the earth falls suddenly then____________.
(A) There is a clear weather
(B) There may be a slow wind
(C) There may be storms and strong winds
(D) None of these

Answer 1

Hint
Atmospheric pressure, atmospheric pressure, force per unit space exerted by the atmospheric region column (that is, the complete body of air higher than the required area). Air pressure may be measured with a barometer (hence the unremarkably used equivalent word measuring device pressure), that indicates the peak of a column of mercury that precisely balances the load of the column of the atmosphere over the measuring instrument.

Complete step by step answer
First of all, you'd have to be compelled to try to come back up with a state of affairs that might cause the earth to shed all of its atmospheres in as very little as one hundred years. That is not probably to be 1st discovered by scientists looking at their barometers.
If air pressure is on the decline, then there's one thing seriously wrong with the earth, and also the call in atmospheric pressure would be neither the primary indicator that we tend to be in bother, nor would it not be our primary concern.
Other than that, wanting the area balls to intake all the breathable air off of our planet, so as for our planets gas pressure to travel all the way down to zero, just about all flowers on earth would 1st have to be compelled to die–as all plant and animal life generate atmosphere–and the seas would have to be compelled to dry up.
We'd be living on a barren desert planet, only then, once there is nothing left of the earth to get atmosphere, would the gasses encompassing our planet begin to mineralize at a rate that might steadily scale back the density of our atmosphere, which might increase temperature extremes between day and night, and leave us unprotected from the extreme ultraviolet radiation from the sun.
Atmospheric pressure acts as an associate indicator of weather conditions. The Explosive decrease in gas pressure of the world shows that there could also be storms and robust winds. Typically it will cause rain additionally.
So, from the above, it is clear that when the atmospheric pressure of the earth falls suddenly then the reason behind it would be storms and strong winds.
Option (C) is the correct answer.

Note
-In the application level, the air pressure is expressed in kilo-pascals.
-It is measured by the barometer or mercury barometer.
-In the lower atmosphere, the pressure declines quickly with height.
-The vertical pressure gradient force is far larger than that of the horizontal pressure gradient and is usually balanced by a nearly equal opposite gravitational attraction.
-The low-pressure system is encircled by one or additional isobars with rock bottom pressure at the center.
-The high-pressure system is additionally encircled by one or additional isobars with the very best pressure within the center.
-Isobars are lines connecting places having equal pressure.
