hydrological cycle diagram atmosphere

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 ..

The atmospheric temperature governs the type of biodiversity, fertility of soil, the hydrological cycle and many other abiotic and biotic parameters of our planet. It acts as a resource - in the sense that optimum temperature promotes the production and productivity o..

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 bas..

Oxygen Cycle - Oxygen is another essential element for living organisms. It is present in large quantities (20.95% v/v) in the atmosphere and is also seen in bound state in water and as oxides and carbonates in rocks. Dissolved oxygen in water is the source of oxygen for aquatic..

Nitrogen is an important structural component of many necessary compounds, particularly proteins. Atmosphere is the reservoir of free gaseous nitrogen and nitrogen compounds are found in bodies of organisms and in the soi..

Carbon is found as graphite and diamond in nature. It also occurs as carbon dioxide in the atmosphere. Because of the position of its electrons, an atom of carbon can form covalent bonds with hydrogen, oxygen, nitrogen, phosphorus and other carbon atoms. Because of this versatility, the c..

Oxygen is another essential element for living organisms. It is present in large quantities (20.95% v/v) in the atmosphere and is also seen in bound state in water and as oxides and carbonates in rock..

Nitrogen Cycle - Nitrogen is an essential constituent of animal and plant matter as it forms proteins, which are the building blocks of life. The ultimate source of nitrogen is atmospheric nitrogen but neither plants nor animals are capable of assimilating free nitrogen. Thus th..

The atmosphere contains a pool of CO 2 . CO 2 is removed from the pool by the photosynthetic activities of plants. It is released back into the environment by respiration which is carried out by all organisms including those micro-organisms (decomposing bacteria) responsible for the decay..
