is the hydrological cycle changing

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 cyclic changes that carbon undergoes in nature is referred to as the Carbon cycle. Carbon in the form of carbon dioxide gets added to the air and gets removed from the air constantly. This addition and subtraction is so well balanced that the percentage of carbon dioxi..

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 the process ..

The cyclic changes in the ovary and uterus are under the control of estrogen and progesterone hormones whose secretion is under the control of gonadotropic hormones secreted by anterior pituitar..

Populations are not stable and always exhibit up and down variations in response to changes in environmental or intrinsic factors. The irregular variations in size of populations are called fluctuations or it is also called as population cycle..

In women, reproductive phase begins with the onset of menses at about the age of 13 years. It ends with its cessation (menopause) at about the age of 45 - 49 years. During this reproductive period, the ovaries and the female reproductive tract undergo a series of cyclic changes which are ..

Based on Hess's law Born and Haber in 1919 developed a simplified and cyclic method to correlate lattice energies of ionic crystals to other thermodynamic data. For example, the net energy changes during the formation of sodium chloride from metallic sodium and chlorine gas can be r..
