Relative clauses are subclauses. The conjunction, that links it with the main clause, is an asking pronoun and it is called relative pronoun. Therefore relative clauses look like interrogative clauses, except for one thing: the interrogative clause has the verb right behind the asking pronoun, whereas the relative clause doesn't begins with the subject, which is preceded by the verb.
