Pressure and Matter: Why Air Holds Us Down

Air Has Weight: Even though invisible, air is made of molecules with mass that press on us.
Atmospheric Blanket: The entire column of air above Earth pushes down, creating pressure.
14.7 Pounds: At sea level, every square inch of your body feels about 14.7 pounds of pressure.
Balanced Out: We don’t get crushed because the fluids inside our bodies push back equally.
Pressure Drop: Climb a mountain, and air pressure decreases as the air thins.
Weather Clues: High and low air pressure systems shape wind, storms, and sunshine.
Everyday Proof: Drinking through a straw works because air pressure pushes liquid upward.
Vacuum Contrast: In space, without air pressure, liquids boil and objects behave strangely.
Altitude Effect: Air pressure changes affect cooking times, breathing, and even sports.
Invisible Force: Atmospheric pressure is a constant, silent companion that makes life possible.
