What causes air movement?

Air moves because warm air rises and cool air sinks, just like when you blow on a hot soup, the steam goes up, and the cooler part stays down.

Imagine your bedroom has a heater. When it's cold outside, the heater warms up the air near the floor. That warm air becomes lighter than the cool air around it. Because it’s lighter, it floats up, like hot air balloons, and when it goes up, it pushes the cooler air down.

Cool air is heavier, just like how ice cubes sink to the bottom of a glass of water. When cool air moves in to take the place of warm air that went up, it creates wind, and sometimes even storms!

So when you feel a breeze on your face or hear leaves rustling, it’s all because of these little air movements caused by temperature changes, like a tiny invisible dance between warm and cool air!
