Q. |
When the barometer reading dips suddenly, it is an indication of – |
A. | Hot weather |
B. | Calm weather |
C. | Storm |
D. | Dry weather |
Answer» C. Storm | |
Explanation: Sudden and great fluctuations of the barometer at any time of the year indicate unsettled weather for several days, perhaps a fortnight. If the barometer falls two or threetenths of an inch in four hours, one can expect a gale of wind. If the surface of the mercury in the cistern of the barometer vibrates upon the approach of a storm, the gale can be expected to be severe. |
