What causes more restrictions or thunderstorm or a cyclone
Answer for class 7 Science
Answers
Answer:
The wind blows due to uneven heating of Earth. This is useful as it is used as a form of energy. Rain is also caused due to moisture-laden monsoon winds. Rainfall is much awaited by farmers as they mainly depend on it for their crops. But do rain and winds always bring happy situations? No. Thunderstorms and cyclones can be caused due to excessive rain and heavy winds, which bring a lot of destruction of property and life. Let us know more!

Answer:
Thunderstorm
A thunderstorm is a storm accompanied by lightning and Thunder. Formation of thunderstorm needs:
Moisture: Moisture required to form clouds and eventually rain.
Front: Front like sea breeze or mountains that help in lifting the warm air upwards.
Rapidly rising warm air: Due to Sun’s heat, the temperature of place rises. The rise in temperature warms the air and create strong winds which arise in the upward direction.
Cause of Thunderstorms
Thunderstorms develop in hot and humid areas like India. The rising temperature produces strong upward rising winds. These winds carry water droplets upwards where they freeze and fall again. The swift movement of the falling water droplets along with the rising air create lightning and sound. This is a thunderstorm. Thunderstorms are dangerous. Lightning kills many people and causes damage to forest and tall structures.
Precautions to be Taken During a Thunderstorm
If you’re outside:
Avoid taking shelter under tall trees or tall Towers.
Try to get into a car or a bus or take shelter inside a building.
Stay away from water bodies.
If you are inside:
Close the windows and doors tightly.
Do not touch electrical equipment or telephone.

Cyclones
Cyclones are violent Storms with an intense spiral and accompanied by strong winds and heavy rains. They are caused due to strong winds blowing around the central area having low atmospheric pressure.
Causes of cyclones
As we know that when water vaporizes, it absorbs heat from the surroundings. Water vapor rises in the atmosphere where it cools down. When water vapor changes back into liquid the heat is released into the atmosphere. This warms the air around it.
The warm air tends to rise and causes a drop in the pressure. The air moves from surrounding high-pressure areas to the central low-pressure area. This cycle is repeated. The chain of events leads to the formation of very low-pressure system surrounded by with very high-speed winds. This weather condition is a cyclone.
