Information report writing

W.A.L.T write an information report about christchuch's waterways.
Here is my writing on christchuch waterways.

The water cycle ( also known as the Hydraulic cycle)  is a process that water goes through between land, ocean and atmosphere.  The water cycle is a recycled process because no water is added.  During the water cycle the water changes state, it goes from being a liquid to a solid and then a gas.  The water cycle goes through a series of stages.  The stages are Evaporation, Condensation, Precipitation, runoff and groundwater.

Evaporation is when the sun heats the water and then the water turns into water vapor.  When the water changes into water vapor it becomes invisible so you can not see this stage happening.  The Evaporation stage happens quicker when the sun is on the water for long periods of time.  Also when the sun has been on the water for a long time the water can heat up to about 100 degrees.  Next the water vapor rises up as a gas and then forms clouds called Condensation. 

Condensation is when the water vapor forms clouds and Precipitation is when the clouds get too heavy and it rains, sleets, hails or snows.  When clouds form it is made of liquid water and ice.  The currents in the air make the clouds move from one place to another.  Since it is so cold in antarctica it always snows and never rains because the rain freezes into ice and snow.  The next stage is when the rain, sleet, hail or snow has fallen and it goes through the next stage called Runoff and Groundwater.

Runoff is when the water runs off the mountains and flows back to sea.  Groundwater is a underground water storage. Some water never makes it back to the ocean because it gets stuck in rocks.  Runoff is water that didn’t get infiltrated(Didn’t sink through dirt.)  Groundwater is a underground water supply which goes to people, wells cities and the ocean.

Overall the water cycle is a never-ending process; it has 5 main stages to make it work they are Evaporation, Condensation, Precipitation, Runoff and groundwater.
