The Hydrological Cycle
Freshwater on land can be differentiated into blue water and green water.
Water found in rivers, lakes, and aquifers is known as blue water. And under our feet, soils hold moisture essential for plants to grow. We call this green water. These plants release green water vapour back into the atmosphere.
Water released into the air forms large flows of moisture that travel overhead, before returning to the Earth's surface, sometimes thousands of kilometres away.
