Atmospheric Pressure
Atmospheric pressure explained in an easy to understand way:
Imagine trying to carry a heavy backpack all day while going about your daily tasks. Just as the backpack's weight presses down on your shoulders, creating a constant pressure, atmospheric pressure results from the weight of the air above us pressing down on the Earth's surface. In this analogy, your shoulders are like the Earth's surface, and the heavy backpack represents the layers of air, or atmosphere, exerting pressure due to their weight.
