Dear Student,
The 3 main differences between Lok Sabha and Rajya Sabha are
(i)Lok Sabha has the tenure of 5 years and is temporary body as it dissolves when the the central government is fallen down or completion of 5 years tenure whereas Rajya sabha is permanent body with the tenure of 6 years.
(ii)The power to convert any government service to All India Services is only vested to Rajya Sabha but not by the Lok Sabha.
(iii) The MPs of Lok Sabha are elected by direct elections but the members of rajya sabha are elected by Indirect elections.
Regards,
