Water cycle information

Water is a very changeable element, and it can be found in multiple ways. Water is constantly changing, going through three states: solid, liquid and gaseous. Water is limited, but thanks to the water cycle it can survive without ever disappearing completely. In this lesson from a TEACHER we are going to show you the water cycle information specially designed for children. In this way, we will try to make you understand why water never disappears. We started!

In order to give you information on the water cycle, we must first know all the forms it can take. Water is not the same in all stages of the cycle, being able to find in three different states that are the following:

• Liquid: The state that we all associate with water, its shape when it is at room temperature. Liquid water is what we drink, with which we bathe, with which we get wet when it rains and which makes up rivers and seas. In this state, water occupies 75% of the planet.
• Solid: The solid state of water is ice and snow. When it starts to get hot it turns into liquid, which is what we see when the ice melts. Water becomes solid when its temperature is below 0º.

• Gaseous: It is water vapor. We find them, for example, in the clouds in the sky or forming fog. It can form moisture in its vapor state.

In the cycle, the water changes its shape on numerous occasions, so to understand the water cycle, one must take into account the methods that make the water change from one form to another.

• Fusion: It is the passage from solid to liquid. When the ice or snow melts, this change of state occurs.
• Evaporation: The passage from liquid to gas. When water reaches high temperatures it evaporates, turning into water vapor.
• Condensation: Change from gaseous to liquid. It is what happens when the water vapor from the clouds turns into water, and falls in the form of rain.
• Solidification: It is the passage from liquid to solid. If the water gets very cold, reaching temperatures below 0º, it turns into ice, turning into a solid state.

Once understood, both the states of the water and the phenomena that cause it to change between forms, we can now talk about the water cycle. The water cycle consists of four phases, Which are the following:

• The Sun evaporates the water from the sea. The sun's rays reach the Earth, and as a result rivers, seas and swamps are heated.
• The water evaporates. The sun's heat causes the water in rivers, seas, and swamps to evaporate. This also affects ice, which first melts to a liquid and then evaporates to a gaseous one.
• Condensation from the clouds. We have already explained that condensation is the passage from gaseous to liquid, well, the evaporated water condenses forming clouds. Therefore, clouds are suspended drops of water that can transform into rain, hail or snow.
• Precipitation. Precipitation is the water that falls from the clouds, that is, the rains. The water that has been evaporated, and that has formed the clouds, is now returned in the form of rain to the earth. To the same site? No, since the wind causes these clouds to change their position, and therefore the water does not fall from where it rose to the sky. The water can fall into the seas, or into the rivers, which will return the water to the sea. And with this ends the water cycle, which repeats itself eternally.

Therefore the water, although it is limited, does not disappear, since the water that evaporates returns to the Earth in the form of rain, and when it is evaporated again it reappears in the form of rain and thus successively. That is why it is possible that the water you drink you can drink again in the future.

The set of actions that is repeated over and over again is the water cycle. We could say that water is recycled through this process, cleaning and renewing itself with each use that nature gives it.

In this other lesson from a TEACHER we discover you How is rain formed offering you an outline of all the steps the water goes through.
