environmental isotopes in the hydrological cycle

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 ..

Summary - 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 change..

Environment of earth includes the whole of atmosphere, hydrosphere as related to biosphere. Therefore, environment includes nature, composition of air, characters of hydrological parameters, sunshine, air pressure, temperature, water resources - their storage and flow and all other physic..

.g., - Atomic plant explosion and miseries caused by it are wrapped up in power generation programme by atomic plants. Miseries of urbanisation are disguised in facilities offered due to urban developments. There are number of such dangerous human welfare programmes - where dangers are realised aft..

Many diseases and pests of plants / animals follow a particular rhythm because of specific response of causal organism to a set of environmental conditions. Hence, disease / pest is more likely to attack a plant/animal if the environmental situations are favourable. These are c..

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..
