Water Conservation and Management

A waterspout is essentially a tornado that occurs over water, featuring a rotating column of air connecting a cumuliform cloud to a water surface. Like tornadoes, waterspouts consist of a spinning vortex of wind and water droplets. They can form over oceans, lakes, or bays, and while generally weaker than land tornadoes, they pose significant hazards to marine vessels and coastal areas.

Yes, it is correct. Only c is incorrect.

Yes, it is correct. As all the three reasons either disturb the ground water level or contaminate it.

Yes, it is correct as irrigation systems were built as early as during the Mauryan Empire.

Yes, it is correct. Regulating and damming of rivers affects their natural flow causing poor sediment flow and excessive sedimentation at the bottom of the reservoir, resulting in rockier stream beds and poorer habitats for the rivers.

Wells and tube wells are the most widely used irrigation source in India, covering approximately 60% of irrigated land. They are accessible to individual farmers and can be installed across diverse geographic regions. Canals require large infrastructure; tanks are region-specific to South India; none of these are as widespread as wells.

Water is an essential molecule required by living beings for all processes. Clothes need to be washed properly to remove dust and dirt which is done by using water and detergent. Huge amount of water is required to wash clothes properly. A very little amount of water is required for bushing, cooking and drinking as compared to washing clothes.

Furniture is the object used in various human activities especially in the households like beds, chairs etc. These objects are mostly made up of woods or glasses. Water is not used in making the furniture.

Dam is a man-made construction which is built to retain water, to manage or prevent water inflow into specific land regions and also to produce hydroelectricity. It is not a natural source of water.

Water required for domestic purposes in various households is supplied from water treatment plants where water is purified, after which this treated water is transferred to domestic areas using water pipes or a network of pipes.

Water present in sea largely consists of salt thus known as saline water which is not fit for human consumption.

Spring is a type of season which comes at the end of winter season and before the starting of summer season. It cannot be a source of surface water.

Water present in natural water bodies on the earth's surface gets evaporated to vapour form and this evaporation takes place by the heating effect of sun rays.

Water is very essential for all life processes on earth. Water is continuously being recycled by the processes of evaporation, condensation to form clouds, precipitation to form rain. Thus water once evaporated again gets recycled on the earth's surface in the form of rain; therefore the ultimate source of water in earth is rain.
