Two activities which require use of more than one bucket of water is washing more than 10 clothes and irrigating a crop field.
17.
These processes are evaporation and transpiration.
18.
Water from the ocean and surface of earth goes into air as vapour through evaporation and transpiration where it cools down and forms tiny water droplets through condensation. These then turn into clouds and returns as rain
19.
Water evaporates from sea, lakes and other water surfaces. Water also evaporates from wet lands, clothes, etc. Water also evaporates from plants through transpiration.
20.
Only surface water freezes as ice, but below the frozen surface, temperature does not fall below 4°C. This temperature is optimum for the survival of aquatic animals in arctic region.
21.
Wet clothes placed on a clothes line dry after sometime because water present in wet clothes is converted into water vapour and released in atmosphere due to evaporation which leaves them dry.
22.
Water kept under the shade of a tree also evaporates because moving air gets heated from sunlight. This warm air provides heat for evaporation of water kept in the shade.
23.
Water is getting polluted:
(i) By industrial waste
(ii) By human activities
Measures to stop water pollution:
(i) We should not throw waste materials and garbage into water.
(ii) We should sensitize people about harmful effects of water pollution.
Associated Value : We should discourage any activity in our life that may cause water pollution
24.
People living in different regions of a country do not get the same amount of water because availability of water depends on the following factors:
