A storm is predicted if atmospheric pressure

Q.A storm is predicted if atmospheric pressure
A.Rises suddenly

B. Rises gradually

C. Falls suddenly

D. Falls gradually

Answer: Falls suddenly

The measurements on a barometer are in millibars. NASA shares that normal air pressure at sea level is about 1,013.25 millibars. When there's a hurricane, the pressure can drop down to 30 millibars. Drops in pressure also help indicate the strength of winds in a storm, as greater drops yield stronger winds.

Low air pressure is associated with bad weather, high winds and rain or snow.

Air is made up of gases and has mass. In the atmosphere, cold air is denser and drier than warm air. When cold air encounters warm air, the warm air rises over the cold air and makes surface air pressure drop. As a result, low-pressure system forms and winds begin to blow. Storms form in response to changes in air temperature. By knowing how different elements react to air pressure, you can predict a storm.
