hydrological cycle diagram

It is the movement of water between aquatic systems, air and land water vapour condenses to form clouds, and eventually rainfall. Plants play an important role in this cycle by the process of transpiration. The upper limit (maximum) of water availability of a soil is called field capac..

Water is an indispensable commodity of life. Water determines the distribution, structure and function of organisms in the ecosystem. Water occurs in three phases - solid, liquid (ice/snow) and gaseous (water vapour). In liquid phase it is vital for the existence of life on this planet. In gaseous ..

Heart - Cardiac Cycle - The heart has an increasing rhythmic activity. It pumps blood by its contraction and relaxation. The contraction of the heart is called systole and the relaxation is called diastole . The contraction and relaxation together constitute the heart beat. The heart beat..

The basis of life on earth is atmospheric cover on earth and natural cycles like carbon, oxygen, nitrogen and hydrological cycles..

Oceans occupy large part of earth. It is almost 2/3 part of earth's surface. It is often presumed that vast hydro source of oceans is a wasteful collection. But, without the presence of oceans, the hydrological cycle is incomplete. In absence of oceans, land wouldnt have receiv..

Atmospheric Resources - The atmosphere around earth is a blessing of nature on earth to have permitted the existence of life on it. Earth is endowed with an excellent resource of atmosphere - both to shield it from sun's harsh rays and other ill effects of celestial bodies as well as to provide the..

Natural Green House Effect - Before interference by any human activities green house effect by a coverage of gaseous blanket was in close equilibrium with earth's surface in the form of equilibria of carbon, oxygen and hydrogen cycles. Contribution of CO 2 by natural decay of plants and a..

Pollution of water is a broad subject dealing with different types of pollutants entering the hydrological cycle. Surface flowing river water, underground water and vast sea water are included in a broad subject of water pollution. Out of them, drinking water pollution is most i..

The basis of life on earth is atmospheric cover on earth and natural cycles like carbon, oxygen, nitrogen and hydrological cycles. Atmosphere is evolved in its present form due to sunlight and rotation of earth on its axis. Many environmental changes like chang..

>Major changes in water resources of world due to disturbances in hydrological cycles. Heavy rainfall tracts are gradually converted into low rainfall tracts, many humid areas being transformed into arid areas, ground water depletion is high and recharging is very low etc. Shift..
