3. Introduction Role of the hydrosphere:
promotes exchanging processes of oxygen and carbon dioxide to the atmosphere
promotes maintaining a constant climate
promotes the flow of the main chemical reaction

4. The Structure of hydrosphere

5. The Chemical components of Hydrosphere
Basic Components
Organic substances
Gases (O2, CO2, N2, CH4)
Mezoelements (N2, P, Si, Al, Fe)
Microelements (all the elements of periodic table)

6. The hydrologic cycle
The role of the hydrologic cycle: it also connects all of the Earth.

7. Problem of Hydrosphere
Pollution
- Chemical
- Biological
- Physical

8. Methods of clearing Mechanical clearing Biological clearing
Chemical methods of clearing

9. Solutions
A restriction of industrial dumps in the rivers, lakes and other water objects.
Clarifications of riverbeds and floodplains from the accumulated dust.
Perfection of "know-how" and technologies of recycling .
Carrying out the rigid control over dump from fields of fertilizers and pesticides.
Carrying out of socially-instructive actions

10. Conclusion
Modern methods of clearing do not give high results as the quantity of the cleared water is equal to anew polluting
