Pressure is defined as the force exerted per unit area. It shows how much force acts on a surface.

Pressure = Force / Area. The SI unit of pressure is pascal (Pa), which equals newton per square meter (N/m²).

Liquids exert pressure due to the weight of the liquid column above a particular point, acting downwards.

Air pressure decreases with increasing altitude because there is less air above a given point to exert pressure.

Wind is caused by the movement of air from an area of high pressure to an area of low pressure.

The eye of a cyclone is the calm center where the wind is light and there is no rain, surrounded by the storm.

A thunderstorm involves strong winds, rain and often lightning, caused by rising warm air and atmospheric instability.

Cyclones form over warm ocean waters when warm, moist air rises, causing a drop in pressure and leading to low-pressure systems.

Water tanks are elevated to create water pressure, ensuring a good flow of water through taps.

A sea breeze blows from the sea to land during the day, while a land breeze blows from land to sea at night due to temperature differences.

A lightning conductor is a metal rod installed on buildings to provide a safe path for lightning strikes to reach the ground.

Roofs may be blown off if the pressure above the roof drops due to high-speed winds, creating a pressure difference.

Cyclones can damage buildings, contaminate water sources with salt, and affect crops due to flooding and high winds.

Stay indoors, avoid tall objects, and do not use metallic items like umbrellas.

Wider straps of bags distribute weight over a larger area, reducing pressure on shoulders and making it more comfortable to carry.

Warm air rises to create low pressure, while cool air moves in to replace it, forming winds and storm systems.

Water droplets can merge and grow larger, eventually falling as rain or hail due to condensation in clouds.

Earth’s rotation causes winds to spin, contributing to the formation of cyclones as air moves towards low-pressure areas.
