Answer 1

$\huge \sf {\orange {\underline {\pink{\underline{Answer :-}}}}}$

(i) Water is a renewable resource as it is renewed by water cycle itself, where three processes take place as evaporation, condensation and precipitation. This process of water cycle is never ending and hence, water is a renewable resource.

(ii) Water scarcity or water stress occurs when water availability is not enough to match the demand for water. It is caused by an increase in population, growing demand for water, and unequal access to it.

(iii) Multipurpose river projects help in irrigation, electricity production, flood control, inland navigation and fish breeding. However, the reservoirs destroy local flora and fauna. Many native villages are submerged, and people lose their livelihood, with little or no hope of rehabilitation.
