Matveeva O. Surgutskaj N. Gr. 5A74
2
Plan Introduction The structure of Hydrosphere
The chemical compounds of Hydrosphere The hydrologic cycle Problem of Hydrosphere Solutions conclusion
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
