Question

what happened to the Rain water when it reaches the Earth surface

Answer 1

hey,

Once there, the gas cools and condenses -- that is, it changes back to liquid. After condensation, precipitation can occur. During precipitation, rain, snow or ice falls to Earth's surface. Once on Earth, the water may evaporate again and return to the atmosphere.

Answer 2

after reaching the earth's surface, the rain water may-
1) seep underground and add on to the water table as ground water
2) go into freshwater bodies like Lakes and rivers
3) add into the seas and oceans as saltwater.
