What is the Water Cycle?
Water - A basic element of nature covers 70% of the earth's surface. The water needs to be refilled, purified, and also circulated over and over again in order to perform its functions. Nature takes care of this job through a process called the water cycle. The water cycle is a phenomenon where water moves through 3 stages (gas, liquid & solid) over 4 spheres (lithosphere, atmosphere, biosphere, and hydrosphere) and completes a full cycle. The water cycle has multiple effects: it controls the surrounding temperature, changes weather and generates rain, helps in the conversion of rocks to the soil, and circulates important minerals through the spheres.
