Answer:
100% of the water is part of the hydrological cycle.
Explanation:
The hydrological cycle is a cyclic process that occurs mainly in the biosphere; this hydrological cycle is in constant movement in the repetition of its cycle; it has different stages, among them the evaporation, condensation, precipitation, infiltration among others.
In the hydrological cycle, 100% of water enters, which is obtained mostly from the oceans; another percentage is extracted from glacier ice and groundwater, also acquires a small percentage of water from the atmosphere and freshwater. And the time of permanence of the water in the hydrological cycle depends on its quantity, so will be the days that it will remain.
