MCQs on Environment and Sustainable Development – Objective Questions and Answers
Q41. Which of the following is not a function of the tree? (R.A.S./R.T.S. (Pre) 1993)
[A] Absorption of carbon dioxide
[B] Absorption of noise
[C] Air pollution
[D] Releasing oxygen
View Explanation
Correct Answer is C.
Trees contribute to the environment by providing oxygen, improving air quality, climate amelioration, conserving water, preserving soil and supporting wildlife.
Hence they clean the environment and are not the reason behind air pollution. In addition to this, trees on both sides of roads reduce the sound pollution by reducing the intensity of sound by 10 to 15 decibels.
Q42. Consider the following : (I.A.S (Pre) 2014, I.A.S. (Pre) 2011)
1. Photosynthesis 2. Respiration
3. Decay of organic matter 4. Volcanic action
Which of the above add carbon dioxide to the carbon cycle on Earth?
[A] 1 and 4
[B] 2 and 3
[C] 2, 3 and 4
[D] 1, 2, 3 and 4
View Explanation
Correct Answer is C.
The decay of organic matter, volcanic action, respiration and burning of fossil fuel etc contribute carbon dioxide to the carbon cycle, whereas plants use carbon dioxide in the process of photosynthesis.
Thus plants do not add carbon dioxide to the carbon cycle rather they release oxygen and consume carbon dioxide. Three natural allotropes of elemental carbon are – fullerene, graphite and diamond. Besides, as a compound, it is found as carbon dioxide, carbonate and Hydrogen carbonate.
Q43. Which of the following does not add the carbon dioxide to carbon cycle on the planet Earth? (U.P.P.C.S. (Mains 2012))
[A] Respiration
[B] Photosynthesis
[C] Decay of organic matter
[D] Volcanic action
View Explanation
Correct Answer is B.
By converting carbon dioxide from the atmosphere into organic matter, plants and trees use a process called photosynthesis. The carbon cycle is not enhanced by it.
In the carbon cycle, carbon dioxide is added by volcanic eruptions, burning fossil fuels, organic matter decomposition, and animal and plant respiration.
Q44. The concept of weathering relates to – (Uttarakhand P.C.S. (Pre) 2006)
[A] Deposition of decomposed material
[B] Change in weather conditions day to day
[C] Natural process leading to the decomposition of rocks
[D] None of the above
View Explanation
Correct Answer is C.
Weathering is defined as mechanical disintegration and chemical decomposition of rocks through the actions of various elements of weather and climate. Weathering processes are conditioned by many complex geological, climatic, topographic and vegetative factors.
