Why earth pin of a three pin plug is thicker and longer

It is longer so that when we put the plug into the socket, earth connection is made first for the safety.
It is thicker so that it is not inserted to the holes of live and neutral.
It has split ends so that the plug is fitted firmly into the socket to avoid sparking.
