Question
Is deforestation associated with global warming? Explain.

Answer

Plants use carbon dioxide gas from the atmosphere for the process of ‘photosynthesis’. When a lot of trees are cut down (i.e., deforestation), then lesser number of trees will be left. The lesser number of trees will use up less carbon dioxide due to which the amount of carbon dioxide in the atmosphere will increase. Thus, deforestation increases the level of carbon dioxide in the atmosphere.
Carbon dioxide gas traps the sun’s rays that are reflected by the earth (causing greenhouse effect). Trapping of rays by carbon dioxide increases the temperature of earth’s atmosphere. This will lead to global warming.
The gradual increase in the overall temperature of earth’s atmosphere due to the greenhouse effect effect by the increased level of carbon dioxide in the atmosphere is called global warming. This explains that deforestation is strongly associated with global warming.

Aanandi took two test tubes and marked them A and B. She put two spoonfuls of sugar solution in each of the test tubes. In test tube B, she added a spoonful of yeast. Then she attached two incompletely inflated balloons to the mouth of each test tube. She kept the setup in a warm place, away from sunlight.

(i) What do you predict will happen after 3-4 days? She observed that the balloon attached to test tube B was inflated. What can be a possible explanation for this?
(a) Water evaporated in test tube B and filled the balloon with the water vapour.
(b) The warm atmosphere expanded the air inside test tube B, which inflated the balloon.
(c) Yeast produced a gas inside test tube B, which inflated the balloon.
(d) Sugar reacted with warm air, which produced gas, eventually inflating the balloon.
(ii) She took another test tube, 1/4 filled with lime water. She removed the balloon from test tube B in such a manner that the gas inside the balloon did not escape. She attached the balloon to the test tube with lime water and shook it well. What do you think she wants to find out?
