Step by step
HOW THE WATER CYCLE WORKS. The water cycle is also known as the hydrological cycle. The water cycle is how the earth's water recycles itself. The cycle includes: [|precipitation], [|evaporation], [|condensation], and [|transpiration]. Earth's water keeps changing from liquid water to vapour and then back again. This cycle happens because of the sun's heat and gravity. There are many different stages of the cycle which depend on each other to do their part in the process. First of all, water [|molecules] from lakes, rivers, streams, reservoirs, and the sea get heated up by the sun and then turn into vapour (transpiration) that rises into the air. This is called evaporation. Next, these water molecules form into clouds, this is because a process called condensation occurs. When the air and the water cool, they form drops of water which then fall to the earth as rain. If they are frozen, they become snow or sleet. This part of the process is known as precipitation. Once the water reaches the ground, it can flow across the land until it reaches rivers, lakes, streams, or the sea. It can also sink into the ground and flow because of gravity through gaps in rock, gravel and sand. Because of this, it reaches these bodies of water too.

Now the cycle begins again, when water is evaporated once more. There is the same amount of water on the Earth now as there was when the Earth began.
