Answer :
Answer:
Pressure reading in barometer will decrease
Explanation:
Barometer is used to measure atmospheric pressure which is nothing but the force exerted due to the weight of an air parcel above any land.
In case where this pressure is low, air rises easily into the atmosphere where it cools down and condenses. Condensation produces clouds made up of water, ice and dust particles. After a certain time period these condensed water droplets fall as rainfall.
However, if pressure would have been high then the air and water vapor have never reached to a higher altitude where they could condense and form clouds.
