Consider rubbing your hand over waxed paper and over sandpaper and you will understand the reason that increased friction causes increased wear. Friction is esentially due to the un-smoothness of surfaces, even though this roughness, in many cases, may be microscopic. Two nearly perfectly smooth surfaces - Teflon on teflon, for instance - will exhibit almost no friction, whereas two very rough surfaces - sandpaper on sandpaper - will exhibit enormous friction.
The rougness, or raised bits of each surface cut into the other surface with the softer surface wearing away more quickly than the harder surface. Sandpaper on wood, for example, will wear away the wood surface first, but eventually the sandpaper itself will be worn to the point where it is no longer effective. This is an extreme example of friction, but it works the same on a microscopic level - say for instance the friction between an automobile's brake pad and the rotor, both of which, to the eye, appear quite smooth.

Can you show an activity to prove that friction causes wear and tear?
Friction has advantage and disadvantage, In that case friction causes wear and tear. there are two activity to prove friction causes wear and tear. 1)some years back in a flight the nose landing gear failed. it turned sidewards, so when landing due to friction it caused fire and also the metal parts in the wheel was disappeared and also the the rubber tube was gone. so, this activity proves us friction causes wear and tear 2)when the car is travelling 100kmph and when the driver put a sudden brake the car stops after a few seconds but if we see the tires it will not be as same as before the driver puts a brake it smooth and it will not have the threads in the tire. The threads in the car are damaged so, this activity also proves that friction causes wear and tear.
