It is wrong to say that friction doesn't occur in smooth surface.. As ideally, no such surface exists, which has 0 value of friction. We can say that the magnitude of friction force is less in smooth surfaces as compared to that in rough surfaces.
Friction opposes the motion of a body. When we go to the molecular level, we can see that the surface of a plane is not smooth but rough.. We cannot see that roughness through naked eyes. But the amount of roughness differs from object to object. The so called smooth surfaces have less roughness as compared to un-smooth surfaces. Hence, the magnitude of friction is LESS in smooth surfaces...

Why does some friction occur with seemingly smoth surfaces?
Some friction will occur with seemingly smooth surfaces because at a molecular level, nothing is smooth.
Why does some friction occur on smooth surfaces?
Some friction will occur on smooth surfaces because even the smoothest of surfaces isn't completely smooth. There are bumps and cracks on the face of the surface when "zooming in" to a microscopic level.
Why is there less resistance on a smooth surface?
Because friction is less on smooth surfaces. Smoother the surfaces, lesser the friction.
What type of surfaces have little friction?
smooth surfaces
Is friction greater with rough or smooth surfaces?
Smooth
Does a smooth surface reduce friction?
There is more friction between the surfaces of 2 smooth surfaces than one smooth surface because there is more surface area.
Why does some friction occur with seemingly smooth surfacers?
Because on the molecular level, they are not smooth No surface is perfectly smooth and even if it were, many molecules of the two surfaces would get close enough together to interact.
What surface has the least amount of friction?
The surfaces used as the measure of lowest friction are generally wet ice on wet ice. Some materials, such as superfluid Helium III have no measurable friction.
Why does rough surfaces have more friction compared to smooth surfaces?
klklkklkl
Are rough surfaces have more friction than smooth surfaces?
True.
Is the amount of friction greater between rough surfaces or smooth and Why?
Rough surfaces, the rougher the surface, the greater the friction.
What causes friction between two seemingly smooth surfaces?
Tiny collisions on the surfaces, called microwelds, cause friction.
