Social: move like a duck to the water.

Water is collected on the Earth´s surface. But not all! What happens with the water not flowing into the rivers, seas or oceans?

 We will see everything about groundwater. This picture is not real, it is just an optical illusion. Don´t you think it is beautiful?

This water is filtered through the soil. It forms underground lakes. It is very important for human beings and animal life. And also, it is important in the deserts, where people must extract it from the ground with wells.
