The Water Cycle By: Niamh Reilly, Chloe Hanna, Chloe Silke
The water cycle The water cycle is very much to do with other weather. Its is also the reason we have rain, sunshine, fresh water and air. The water cycle is a cycle which is always in motion and never stops. DID YOU KNOW ? If water wasnt a renewable resource earth would run out of fresh water in a month.
The water cycle The earth has a limited amount of water. That water keeps going around and around and around and around and (well, you get the idea) in what we call the "Water Cycle". The water cycle is earths way of recycling water. It describes the journey water takes as it constantly passes between the atmosphere, the oceans and the land.
The water cycle There are four stages to the water cycle these four stages are all equally important to the cycle, the four stages include : Evaporation Condensation Percipitation Run off/ See-page
The water Cycle Evaporation Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapour or steam. The water vapour or steam leaves the river, lake or ocean and goes into the air. Evaporation - picture
The water cycle Condensation Condensation water vapour in the air gets cold and changes back into liquid(tiny droplets), forming clouds. This is called condensation. Condensation - Picture
The water cycle Precipitation Precipitation occurs when so much water has condensed that the air cannot hold it anymore. The clouds get heavy and water falls back to the earth in the form of rain, hail, sleet or snow. Precipitation - picture
The water cycle Run-off / Seepage Run-off : Water moves downhill and across the land (on the surface or by rivers and streams) to return to the sea. See-page : some water seeps into the ground, where it is stored in the rocks and in the soil. Picture
The water cycle When the water ends up on land, it will either soak into the earth and become part of the ground water that plants and animals use to drink or it may run over the soil and collect in the oceans, lakes or rivers where the cycle starts all over again.
The water cycle So lets take a re-cap over the water cycle : Evaporation Condensation Precipitation Run-off / seepage
The water cycle In this diagram you can see where the four stages are marked in: Evaporation, Condensation, Precipitation, run-off/ seepage

The water cycle Clouds are also linked with the water cycle mostly because they help to make the cycle work there are mainly three different types of clouds: Cirrus Cumulus Stratus Clouds are grouped according to their shape and height at which they occur. The darker the colour of the cloud, the more likely it is that precipitation is about to occur.
The water cycle Cirrus Cirrus clouds are wispy like a lock of hair. They occur at high altitude. The are made of ice crystals. They are associated with fair weather. Picture
The water cycle Cumulus Cumulus clouds are fluffy or woolly in appearance. They accrue at medium altitude. They are also know as fair weather clouds. They can bring rain if they darken in colour. Picture
The water cycle stratus Stratus clouds occur at low altitude. They form thin layers and can block out the sun. If they reach ground level they are called fog. The bring continual drizzle and light rain Picture
