Continued accumulation of the molecules of water saturates the air and hence rain clouds are formed though condensation process. Precipitation in the form of rainfall, snow then occurs.
Where precipitation occurs depends on whether or not the clouds were transported to land by advection process, or remained in the ocean. The cycle is at this point complete and the process starts all over again. In the case where the clouds containing the water molecules are transported to land from the ocean by air currents through a process called advection, condensation as well as precipitation occurs over land.
Some of the water on reaching the ground evaporates to the atmosphere while some penetrate to the ground to form underground water. But the largest portion of the water goes back to the ocean in the form of surface run off through streams and rivers. On diversion to farms, the water is mainly used for irrigation purposes. Yet in these farms chemical fertilizers and pesticides are widely applied. The overflow of water is then released back to the rivers, often without proper treatment, carrying with it elements of the chemical fertilizers as well as those of pesticides from the farms, thus polluting river water downstream as well as lakes, seas and oceans into which he rivers drain their water.
Which is harder to control? Point pollution is pollution that originates from a single source. Non-point pollution originates from many points. Non point pollution is harder to control because the sources are many thus not easily identifiable.
The movement of tectonic plates could be in the direction of each other or drifting apart. When the plate drifts apart, and it so happens that their boundary is in the ocean, the result is to open a gap in this boundary. This gap, depending on the extend of movement, could form an oceanic basin, a mid oceanic ridge, or even a volcano. Underground mining pollutes underground water. Moreover, its water becomes still more polluted as people throw into this river the dead bodies and corpses of animals.
Along with the inland water-bodies a huge amount of water is stored in the form of ice on the mighty peaks of the Himalayan ranges and under the ground.
Even one-third of this potential water resource has not yet been developed. India is an agricultural country. Water is essential for agriculture. Our country gets rainfall by the monsoons, but this rainfall is not equally distributed all over the country.
Even though the annual average rainfall is satisfactory, it is unequal and uncertain. About 80 per cent of the country's rainfall occurs in four months i. So, eight months of the year remains almost dry. The west coast, east coast, West Bengal, Bihar and north-eastern States have adequate rainfall whereas insufficient rainfall occurs in north-western region, south Indian plateau and mid-Gangetic plains.
So floods occur in the heavy rain-fall areas whereas drought breaks out in the rainless areas. Sometimes the summer monsoons break late and close earlier, and in some years break earlier and close earlier too. Again at times it doesn't rain in the growing period of crops in the months of July and August. Sometimes late monsoons also damage crops; therefore, this monsoon rainfall is very uncertain. As a result of such irregular, unequal and uncertain monsoon rainfall, natural calamities like flood and drought have their devastating effects in our country.
About 70 per cent of our people depend on agriculture. Agriculture depends on rain. When agricultural products are affected, it causes want of food and industries dependent on agriculture also hamper in production. Satisfactory agricultural products help in the growth and prosperity of the country. But flood and drought cause problems in country's prosperity.
Flood is an annual problem in some areas of our country. India is worst affected by floods amongst all the tropical countries. Houses are washed off, domestic animals and human beings meet their death and crops are severely damaged by floods. Besides, railway tracks and roads are washed away and agricultural lands are covered with sand. Moreover, people suffer from various diseases by drinking polluted water and owing to unhealthy and damp environment.
Watershed resources play a significant role in the development of a country depending on the location of a watershed; we can get water for domestic, agriculture and industrial uses. It is for this purpose, proper evolution and management of water resources acquires significant importance.
Water resources is also affected by Stalinization resulting from discharge of saline agricultural and mining drainage water to river systems and the increased rate of natural discharge of saline groundwater to surface water resources in irrigated and non irrigated areas.1/5(1).
Water is one of the most precious resources the earth provides to mankind. Its use in modern age is manifold. We drink water to satisfy our thirst. We use it for domestic needs, irrigation, industrial use, transportation, power production and waste disposal. Water is universal solvent. Thanks to our nature; it is very rich in water.

Water Resources Essay Water is an essential resource. It is also a nonrenewable or finite resource: While water supplies can be regenerated by creating new water molecules from their elemental beginnings (hydrogen and oxygen), the energy required to create large usable pools of water is currently too energy costly to be feasible. WATER RESOURCES Water is an essential element to our everyday existence. Its role is vital in the sustenance of all life forms, as well as in agricultural, industrial, households, recreational and environmental activities.
