The Water Cycle

the water cycle  

Introduction
The water cycle is very important. The water helps grow the food we eat. Without it we would be dead. Earth will be just a desert with no life or water.


Evaporation
The water cycle starts off as just water. The heat of the sun evaporates the water and it rises up into a cloud. This is called evaporation. eg: If I left a glass of water in the sun and go away four hours this happens. The water has evaporated And became a cloud.                                                                                                                                                  


Condensation
Inside the cloud the water drops push together creating bigger drops. The drops continue to travel up until they get too heavy and gravity pulls it down.


Precipitation
inside the cloud the drops get heavier and heavier until the drops start pouring down. this is called precipitation.
if the drops go further up the freeze and that creates hail and snow.


Run-off
when the water hits land the water travels out to sea or becomes groundwater. this is called run-off.


Conclusion

now you know all about the water cycle. it is important to earth in many different ways.
