Water Conservation and Management

The water cycle, also known as the hydrologic cycle or the H₂O cycle, describes the continuous movement of water on, above and below the surface of Earth. The water moves from one reservoir to another, such as from river to ocean or from ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, runoff and subsurface flow.

It does not provide breeding ground for mosquitoes as this water is below ground and not available to mosquitoes for breeding.

Plants need water. If there is no water, all plants will die as water helps them to grow, to prepare food etc.

 Major source of groundwater replenishment is by rain.

In-stream water use refers to water utilized without being removed from its source. Hydroelectric power generation is a major in-stream use because water flows through turbines while remaining in the river. Irrigation, domestic use, and waste treatment consume or remove water from streams.

Same amount of rain water does not fall in different places at same time. The rainfall totally depends on the weather conditions and all places do not have same type of weather at same time.

Sleet is just rain drops that freeze into ice pellets before reaching the ground. Sleet usually bounces when hitting a surface and does not stick to objects. However, it can accumulate like snow and cause a hazard.

Water purification is the process of removing contaminants from surface water or groundwater to make it safe for human consumption. The water collected in reservoirs is sent to water treatment plants for purification.

This is a wrong statement. Another name of water cycle is hydrologic cycle.

If adequate reservoirs are available, then canal system is used, in which the main canal, which receives water from one or more reservoirs or from rivers, is divided into branch canals having further distributaries to irrigate fields. However, in areas where canal flow is insufficient or irregular due to inadequate reservoir; the lift system is used. Water is directly drawn from the rivers. Tanks and wells cannot be the answer as they store run-off water or water through seepage.

In this method, the water flowing on the houses, roads, ground or lawns etc, is collected in ponds and storage tanks. This water is allowed to penetrate (percolate) into the ground to recharge the ground water. This is also known as water harvesting.

The underground water is the main source of inland lakes.

Rain is the source of soft water.

This is the correct answer.  Rain water is the primary source of water. Ground water and surface water is the secondary source of water. Boiling is the process that can be use to kill the germs present in the water and saving and using water carefully is called water conservation.
