Answer:
100% is water that comes from the rain.
Explanation:
Some of the water obtained from the evaporation of rivers, lakes and other sources rises to the troposphere where it condenses as clouds, as part of the hydrological cycle. Later it rushes to the earth in the form of a meteorological phenomenon known as rain.
The rain falls in liquid form to the earth, where it is used by many organisms, plants, and living beings, which need water to live, this is a process that is repeated cyclically.
