Writing: Information Report On Water Cycle

This term we have been learning about the Water Cycle. Here is my information report on the Water Cycle.

Water Cycle

The water cycle is a never ending cycle that has four main stages: Evaporation, condensation, precipitation and runoff/groundwater. During the water cycle there is no new water created, for it is all recycled so that no water is wasted. Throughout the water cycle the water changes state between gas, liquid and solid.


Evaporation is where water on the earth's surface like seas, lakes and rivers gets sunlight that cause it to turn into a vapour/gas. Water vapour in the air is known as humidity. The Evaporation stage works better on a hot day, as there is more sunlight on the water. Condensation is when water vapour gets cold and condenses back into a water droplet. When the water droplet collides with dust it forms a cloud. When water in the clouds gets heavy enough water starts to fall - this step is precipitation.

Precipitation is the stage where water falls from the clouds in two different states. These states are solid and liquid, solid being snow and hail and liquid being rain. In places like deserts sometimes it only rains one inch per year but, in the coldest mountains it can rain up to 600 inches of rain per year. Once the precipitation hits the ground it becomes runoff.


Runoff is the stage where water hits the ground and starts flowing into rivers, lakes and the sea. Runoff is what helps recycles the water as it takes the water back to places where it can evaporate. Some of the water from runoff goes into the ground to become our groundwater. Once water becomes groundwater it can go through the aquifers and become our tap water.
Overall the water cycle is the most important thing on the planet because without it we wouldn’t survive. Evaporation and condensation get the water stored in a cloud that, when cold enough becomes precipitation. Afterwards it becomes runoff or our groundwater that gives us our drinking water.
