Over two thirds of the Earth is covered with water. Water doesn’t leave the Earth, it gets cleansed through the water cycle. The water cycle is the journey of water. It starts with the sea/ocean and then into the clouds. After that, it turns to rain, to rivers/streams and then back into the sea/ocean again. DID YOU KNOW? Did you know that the water cycle is also known as the hydrologic cycle? Did you know that the Earth has been recycling water for over four billion years? Did you know that when you drink water, you swallow the same water that King Tutankhamun and the Romans drank? 1.Evaporation Evaporation is when the water in the ocean warms up and bubbles. This turns it into a gas known as water vapour. This is evaporation. 2.Condensation After the first process, the water vapour then rises and collects in the clouds. When the water cools, it condenses and turns back to liquid. 3.Precipitation Once it condensates, it falls back to the Earth as rain, hail or even snow.
