Answers
Answer:
high speed wind reduces air pressure:
take two balloons of approximately same size and put little water into them, to make them heavy. inflate each of the balloons and suspend them from some fixed support such as rod.so the balloons are 10 cm apart from each other. now take a cardboard sheet and roll it like a tube, holding the tube close to the gap between two balloons blow hard. we observe the freely suspended balloons move together.
Reason: when high speed air moves through the gap in between the balloons the pressure of air falls in the gap. thus the air at the higher pressure on the side of balloon forces them inward
1)Cooler air from the surrounding areass of the equator comes towards the equator to fill the place of warm air which rises up due to sun's heating. Hence, wind currents are generated due to uneven heating.
2)When warm, moist air moves upward in an updraft, puffy cumulus clouds may form in the atmosphere. The moisture in the air condenses into water droplets as it rises. The cloud will continue to grow as long as warm air from below
3)To form a cyclone, warm, moist air over the ocean rises upward from near the surface. As this air moves up and away from the ocean surface, it leaves is less air near the surface. So basically as the warm air rises, it causes an area of lower air pressure below
three damaging effects:
1)loss of life and property.
2)Damage of building and shelters.
3)Damage of cops and goods.
safety measures :
1)Avoid the high building area.
2)Be educated about cyclones.
3) Watch whether reports.
