Understanding Earth's Water Resources
Out of this vast water resource, only 3% is
freshwater that can be used by humans.
Freshwater sources primarily include
surface runoff and groundwater, which
are part of the Earth's hydrological cycle.
The hydrological cycle is a continuous
natural process involving the evaporation
of water from various water bodies, cloud
formation, precipitation, and water
returning to these bodies, ensuring its
renewability.
