 The cycle starts when water on the surface of the

              Earth evaporates.


           Evaporation means the sun heats the water which

              turns into gas.


           Then, water gets collected  as water vapour in the


              sky ,which turns into clouds.


           Next, the water in the clouds gets cold and it

              becomes heavy which changes into liquid

              form  again. This process is called condensation.


           Then, the water falls from the sky in the form of

              rain, snow , and  hail. This is called precipitation.


           The water sinks into the surface and also collects


              into lakes, oceans, or aquifers. It evaporates again

              and continues the cycle.
