World water cycle
This picture shows us the world water cycle. First the water is evaporated, then it rises and condenses and it forms clouds. When it is cooled it fall down, this is the precipitacion. It can be snow or rain. The water flows on the surface and it forms rivers, lakes...., or the ground sucks it. This is the infiltration. The water that the ground sucks form aquifers. The water of the rivers flows into the sea or oceans and the water cycle repeats.
