Nature's Water Purification Cycle

Water, the source of all life of the kind we know on Earth, is always in movement naturally – it is perpetually moving to a different location and changing its form. The energy source for this continuous never-ending transformation is sunlight.

The Water Cycle

The figure on the right displays Nature's 4-process Water Cycle (also known as the Hydrological cycle).

The four processes are: 
  • Evaporation & Transpiration - this process removes salts and other ingredients from seawater and delivers pure fresh drinking water (as water vapor) into the atmosphere
  • Vapor Transport - this process ensures that the pure fresh drinking water is available everywhere
  • Precipitation (Condensation) - this process deposits the pure drinking water on the ground and facilitates a process called Chemical Weathering that scrubs carbon dioxide from the atmosphere and is part of Nature's Carbon Cycle
  • Surface and ground runoff - this process adds the results of the precipitation process into the Ocean

All of these processes are in various stages of progression at any one time time everywhere around the world.

Drinking Water

Water, fit for consumption by humans, animal, insect and plant life, is available in the atmosphere.

The appropriate name of the Water Cycle is Water Purification Cycle.
