The rough surface causes a lot of friction when the matchstick rubs against it. Friction causes heat (try this for yourself by rubbing the palms of your hands together- they feel hot. Then consider how smooth our skin is in comparison to the rough surface, so you appreciate how much heat it generated.) The heat causes the wood of the matchstick to set alight.
Actually, the head of the matchstick is coated in a more flammable substance (phosphorus), which makes lighting even easier.

What do you call it when a rough surface scatters lights in a lot of different directions?
Diffuse reflection.
How lights behave when it strikes in smooth and rough surface?
When light strikes a smooth surface (like a mirror), it is reflected. When it hits a rough surface (like a sheet of paper) it is diffused, meaning the rays of light are scattered.
The most friction is caused by the rubbing between objects that are?
rough
What word means smooths out a rough surface?
abrasive means to smooth out a rough surface
What material produces the most friction in a rough and dry surface?
While there is no definite answer, the substance that produces the most friction when rubbing up against another substance is almost certainly rubber. This is why it is used in tires.

What role does rubbing the match head on a rough surface have in reaction involved in the burning of a match?
Rubbing the match head mixes together the two chemicals that make up the surface of the match head. Then they react with the air and cause an exothermic reaction.
Why does a matchstick burn on rubbing it on the side of a matchbox?
The heads of strike-anywhere matches are composed of two parts, the tip and the base. The tip contains a mixture of phosphorus sesquisulfide and potassium chlorate. Phosphorus sesquisulfide is a highly reactive, non-toxic chemical used in place of white phosphorus. It is easily ignited by the heat of friction against a rough surface.
