Text: Water

Everybody knows that is one of the most important natural things, and without it life would be impossible. The seas and oceans cover about seven tenth of the Earth but water is also contained in the soil, in the atmosphere and in all living bodies. More than half of the human body consists of water, which also forms a large part of the food we eat, such as vegetables and fruit.

Man can live as long as ninety days or more without food, but we cannot live many days without water. Water is known in three states: ice, liquid water and steam. When water boils steam is formed, and in the cold weather water turns into ice. Pure water which chemists call H₂O is not almost found in nature. This is because water is able to dissolve from so many things from the air, the soil, and so on.

We know that there is much difference between sea water or ocean water, on one hand and water in ariks that flows down just from mountains, on the other hand. Such arik water was always drunk by people as it was clean. River water flowing into seas is cleaner than that which is in the sea. In mountains people drink river water.
