Answer:
A smooth surface has smaller hills and valleys. There are also electrostatic attractions between surfaces, but these are weaker than the physical barriers to sliding. SO AIR HAS FRICTION BUT IT WON'T HURT AS DUE TO ITS WEAK APPEARANCE
Explanation:
Even though air is a fluid, the air molecules still rub across the surface of the Earth.
Air is also channeled and diverted by buildings, trees, and hills. All these effects cause friction, a rubbing of the air molecules across the surface.
