When stones are stricken against one another, then there are chances of transfer of electrons from one to the other. So positive in one and negative charges in the other are produced. Now comes a chance to have an electrical discharge between them which leads to produce sparks in air.
by grating stones against each other, sparks will be produced due to friction, nd u can start a fire..

When the stones collide, they generate friction which in turn generates heat. The greater the friction, the more heat that is generated.
Strike a flint against steel.
Rivers have a granulating effect on stone - the pressure of the water and the constant motion of stones against one another gradually reduces stone to sand.
