Hydrologic Cycle

Hydrologic Cycle. The Hydrologic Cycle. More than 97% of all Earth’s water is in the oceans. Only 1 % of Earth’s water is available to us as water vapor, groundwater, and freshwater. The Hydrologic Cycle. Earth’s waters are constantly circulating. The driving forces are: Heat from the Sun
