ASSERTION (A) : Flowing as a sheet across a land surface , running water picks up particles and moves them downslope into a stream channel.

REASON (R) : Stream flow always transport all kinds of sediment load downstream.

• Both (A) and (R) are true.

• Both (A) and (R) are true , but (R) is not the correct explanation.
