@Michele_Laino
No that is wrong..
that is why i was asking him whether he knows about weathering

Weathering of rocks is a process by which rocks break down
there could be many reasons for this

Mechanical weathering is the one which happens due to physical forces.. NOT CHEMICAL REACTIONS. so the chemical property of the rock doesn't change.
