Because there is less traction for an object to grab onto on a smooth surface rather than when an object runs over a rough surface.
Yes, smooth surfaces can still produce friction. Friction is caused by the resistance between two surfaces when they are in contact with each other, not only by the texture of the surfaces. Smooth surfaces can still generate friction, although the amount of friction may be lower compared to rough surfaces.
A smooth surface will produce the least amount of friction compared to a rough surface. Friction is caused by the resistance when two surfaces slide against each other, and smoother surfaces have fewer microscopic irregularities that create friction. The coefficient of friction is lower for smooth surfaces.
Two rough surfaces in contact will produce more heat due to increased friction compared to two smooth surfaces or a smooth and rough surface. Adding oil between two surfaces will reduce friction and heat generation.
Rough surfaces typically produce more friction compared to smooth surfaces. This is due to the increased contact points between the surfaces, resulting in more resistance to motion.
Because friction is less on smooth surfaces. Smoother the surfaces, lesser the friction.

Yes, a smooth surface reduces friction because there are fewer microscopic irregularities that can create friction between surfaces. This results in less resistance when two objects slide or move against each other.
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...
Surface friction is defined as the resistance of an object experiences during motion. So, for the same object, a smooth surface has less friction than a rough surface. Think about skating on ice or a piece of plywood!
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.
Surface types can affect the force of friction because as the surface gets rough and rougher it has more friction and smooth surface has less friction. if we compare the affect of friction force on a ice and road. Road is much more rough than the ice chunk and if we slide a ice hockey puck on each of the surfaces, we get that smoother surfaces has less friction.
It is on smooth surfaces because the amount of friction is less.
