Air Pressure and Atmospheric Layers Explained

The video explores the concept of air and its properties, starting with an experiment to demonstrate air pressure using a bottle and cardboard. It explains that air is present everywhere and exerts pressure in all directions due to its fluid nature. The video then introduces the atmosphere, its layers, and how air pressure varies across these layers, being highest at the bottom. Finally, it touches on the concept of wind and poses questions about its impact on air pressure, to be explored in the next lesson.
