Question

Answer each of the following questions briefly.
(a) Why is it not good to wash clothes in hard water?
(b) In what ways could the natural water cycle be affected if large forests are cut down?
(c) List at least four steps by which you can help to conserve water in your home.

Answer 1

(a) It is not good to wash clothes in hard water because the soap does not form lather with hard water. In result, it forms a scum, which sometimes damages the fabric. Also, washing of clothes in hard water takes longer time to clean the cloth.

(b) Plants absorb carbon dioxide from the atmosphere to perform photosynthesis. If large forests are cut down, the level of carbon dioxide in the atmosphere will rise. As a result, carbon dioxide will trap more radiations, thereby adding to global warming. Global warming refers to an increase in earth’s temperature. An increase in earth’s temperature disturbs the natural water cycle. As a result, there will be a change in rainfall pattern, which in turn could lead to drought.

(c) Steps to conserve water at home:

• Turn off water while brushing teeth.
• Wash only full loads of dishes and clothes.
• Don’t over water lawns and landscapes.
• Take shorter showers.
• Mop the floor instead of washing it.
