Answer
(i) Loss of water due to evaporation is highest in tanks due to large area coverage and its shallow depth.
(ii) Many cities in India have banned the construction of tubewells because excessive extraction of groundwater lowers the water table, leading to water scarcity. It can also cause the ground to sink which can damage buildings and infrastructure.
(iii) Rabi crops are grown in areas with irrigation facilities because they are sown in winter when rainfall is low. These crops, like wheat and barley, need a regular water supply, which is provided through irrigation.
