Answer:
Within the hydrological cycle, each water molecule remains a different interval of time in one place, depending on where it is stored. Thus, the water accumulated in the deep underground layers can remain there for up to 10,000 years, that of the glaciers for a maximum of 100 years and that of a river for up to six months.
Step-by-step explanation:
Water from the oceans, rivers, clouds, rain, etc. Follow a cyclic movement. The surface water evaporates, while that of the clouds precipitates and drains down the rivers to the seas and oceans or infiltrates the Earth. Be that as it may, the total amount of water on the planet does not change. This cycle begins with the evaporation of water from the earth's surface thanks to solar energy. Water vapor moistens the air as it rises, cools on solid particles and condenses into microdroplets, which join together and form clouds. Then, the drops of water rush to the ground in the form of rain, hail or snow, depending on the temperature of the atmosphere. Finally, water ends up returning to the oceans through different channels. In total, the planet contains some 1,385 million km3 of water in its different states, of which almost 97% is salt water found in the oceans, while the rest corresponds to fresh water that is distributed among the polar caps , rivers, lakes, underground aquifers and the atmosphere.
