What is green water?

Green water refers to the water that is stored in the soil and vegetation. This concept encompasses the moisture that is retained in the ground and utilized by plants for growth through processes like transpiration, where water is absorbed by roots and then evaporated from plant leaves into the atmosphere.

Green water plays a vital role in agriculture and natural ecosystems, as it contributes significantly to plant productivity and overall ecosystem health. Unlike blue water, which is found in rivers, lakes, and reservoirs, green water emphasizes the importance of soil moisture and its interaction with vegetation in the water cycle.

The other options do not accurately represent the concept of green water. Water stored in rivers and lakes is referred to as blue water, while artificially enhanced water does not relate to the natural storage in soil and vegetation. Oceanic bodies contain saline water, which also does not apply to the definition of green water.
