Plan Introduction The structure of Hydrosphere The chemical compounds of Hydrosphere The hydrologic cycle Problem of Hydrosphere Solutions conclusion

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

The Structure of hydrosphere

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)

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

Problem of Hydrosphere Pollution - Chemical - Biological - Physical

Methods of clearing Mechanical clearing Biological clearing Chemical methods of clearing

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

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