With every stroke of the chalk piece it leaves some of the chalk on the board. This abrasion of the piece of chalk causes it to wear down. This is similar to why the rubber tyres of cars wear down when they are driven over a road surface.
a chalk piece can be broken easily but not an iron piece because iron has greater intermolecular force of attraction which keeps the particles together . the strength of this force of attraction varies from one kind of matter to another
