V. Read the text about the problem of water pollution and express your understanding of this problem. Does it exist? Can you describe the situation in your city?
WATER POLLUTION
Everybodys talking about pollution. Pollution is what happens when things we eat, the place we live in and the water we drink are made dirty and unhealthy by machines and factories. Factories pay for the water they raise, but in our homes we only pay to have water. After that we can use as much as we want. Apparently we lose every day enough water for the whole town. Finally what we have left in our rivers we make so dirty that we cant use it.
It should be pointed out that the outcry about the threat of water pollution faced by many rivers, lakes and oceans come from different environmental organizations. Baikal first faced such problems almost 200 years ago when it stores were settled and crop farming and cattle breeding developed, and timber was felled. The floating of loose timber, particularly, polluted its waters. The pollution problem grew, especially after the war because of the accelerated development of industry and the rise of cities in Siberia.
The problem of Baikal protection was discussed by the scientists. Nevertheless it is difficult to solve this problem once and forever. Baikals beauty and purity could be maintained at the same time that its rich resources were tapped.
VI. Read the first paragraph of the text on p. 39-41 Stops in the water cycle: water on land and give other cycles in nature (e.g. the birth and death of an animal, the production of some goods, etc.).
VII. What are the processes of the water cycle? Read the description of each process and match it with its name.
1. It is an important process where rain water soaks into the ground, through the soil and underlying rock layers. Some of this water ultimately returns to the surface at springs or in low spots downhill. Some of the water remains underground and is called groundwater. As the water infiltrates through the soil and rock layers, many of the impurities in the water are filtered out. This filtering process helps clean the water.

2. It is the opposite of evaporation. It occurs when a gas is changed into a liquid. It occurs when the temperature of the vapor decreases. When the water droplets formed from condensation are very small, they remain suspended in the atmosphere. These millions of droplets of suspended water form clouds in the sky or fog at ground level. Water condenses into droplets only when there are small dust particles present around which the droplet can form.
3. It is the process where a liquid, in this case water, changes from its liquid state to a gaseous state. Liquid water becomes water vapor. Although lower air pressure helps promote evaporation, temperature is the primary factor. For example, all of the water in a pot left on a table will eventually evaporate. It may take several weeks. But, if that same pot of water is put on a stove and brought to a boiling temperature, the water will evaporate more quickly. During the water cycle some of the water in the oceans and freshwater bodies, such as lakes and rivers, is warmed by the sun and evaporates. During this process, impurities in the water are left behind. As a result, the water that goes into the atmosphere is cleaner than it was on Earth.
4. When the temperature and atmospheric pressure are right, the small droplets of water in clouds form larger droplets and this process occurs. The raindrops fall to Earth. As a result of evaporation, condensation and precipitation, water travels from the surface of the Earth goes into the atmosphere, and returns to Earth again.
5. Much of the water that returns to Earth as precipitation runs off the surface of the land, and flows down hill into streams, rivers, ponds and lakes. Small streams flow into larger streams, then into rivers, and eventually the water flows into the ocean. This process is an important part of the water cycle because, through surface runoff, much of the water returns again to the oceans, where a great deal of evaporation occurs.
6. One final process is important in the water cycle. As plants absorb water from the soil, the water moves from the roots through the stems to the leaves. Once the water reaches the leaves, some of it evaporates from the leaves, adding to the amount of water vapor in the air. This process of evaporation through plant leaves is called transpiration. In large forests, an enormous amount of water will transpire through leaves.
