Es una imatge que represental'aigua

Water is one of the most important elements of the Earth : in fact covers three quarters of our planet and , no water, no living being could live .
The total amount of water on Earth is , more or less , always the same , but not always in the same place .

Most of the water is in the oceans and seas , rivers and lakes , but also water below ground : we get there the men digging holes called wells.
 With the heat of the sun, the water evaporates and rises through the atmosphere : at a certain altitude, the cold , the steam condenses back to water droplets , forming clouds.
