Q1: Why are winds stronger on some days than on others? Answer: Wind speed depends on the pressure difference between two regions. If the difference between the High Pressure and Low Pressure areas is very large, the air rushes faster to fill the gap, resulting in stronger winds.
Q2: Why are water tanks usually placed at a height? Answer: Liquid pressure depends on the height of the water column (depth). Placing the tank high on a roof increases the vertical distance (height) between the tank and the taps on the ground floor. This creates higher pressure, ensuring a strong flow of water.
Q3: Can air pressure really crush us? Answer: Theoretically, the weight of the atmosphere is massive (like carrying a car on your head!). However, it doesn’t crush us because our bodies contain fluids and air that exert an internal pressure equal to the atmospheric pressure, balancing the forces.
Q4: If the Earth stopped rotating, would cyclones still form? Answer: Likely not in the same way. The spinning motion of a cyclone is driven by the Coriolis effect, which is caused by the Earth’s rotation. Without rotation, air would rush directly into low-pressure areas without spiraling, preventing the formation of the characteristic cyclone vortex.
