E.g., • The toy is on the table

• She is fond of music

As in first sentence on shows relation between noun (toy) and noun (table)

In second sentence preposition of joins a noun (music) and a adjective (fond)

• At, in , on

At is used to indicate specific point of time.

In is used to indicate a longer period of time.
