Water cycle can be explained through the following diagram,

 
Water from the sea goes into the atmosphere through evaporation. There it gets converted into cloud through condensation. From the clouds, it reaches the ground through precipitation. It goes into groundwater through infiltration (seeping through the pores of soil) and from there it goes into the sea through groundwater runoff.  So, water needs to follow these steps to complete the cycle.
