PLANET EARTH – THE BLUE PLANET
Earth is the only planet in our solar system where humans can live. It has got oceans, seas, rivers, lakes, many different forms of life, and oxygen to breathe. The Earth is called the Blue Planet because it has got a lot of water. If we look at the Earth from space, the oceans and the atmosphere make the planet look blue.
About seventy-one per cent of the Earth is covered with water. About twenty-nine per cent of the Earth is formed by land called continents.

OCEANS - THE BLUE FACTOR
Why are the oceans so blue? The light of the Sun has got all the colours of the rainbow. When the light hits water, part of the light is absorbed. Blue light is absorbed by water very easily.
OCEANS - THE SALT FACTOR
Why has the ocean got salt? When water goes in rivers, it gets mineral salts from the rocks. This salty water then goes into the seas and oceans. Ocean water evaporates in the process of the water cycle, but the salt doesn't evaporate and stays in the ocean. LEARNING ABOUT WATER IN SPAIN
