    Chipko Andolan is a well-known example of conservation of which form of nature?
    Solution
    Chipko Andolan originated in the Reni village of Garhwal in the early 1970s. The movement involved the village women hugging the trees and preventing them from being felled. This act was for preventing forests from being cut down is an example of conservation of the forests/jungles.

  • Question 3
    1 / -0
    Which of the following is the proper way to use water economically for farming?
    Solution
    Drip Irrigation is a method in which water flows through a filter into special drip pipes, with emitters located at different spacing.
    It is a method of using water economically as the water flows drop by drop so there are no chances of wastage of water.
    The other three options are water harvesting systems.
    Thus, the correct option is D.

  • Question 4
    1 / -0
    One boy goes to school on his vehicle. On the way, he reaches to a cross-road where red signal is shown. He turns off his vehicle until green signal appears. From this, he has used which R to save the environment.
    Solution
    The three R's for the conservation of energy reduce, reuse and recycle. Since the boy turns off his vehicle until the green signal, the boy is conserving fuel. This shows that he curtails the use of fuel when not necessary, thus using 'Reduce' of the three R's to save the environment.
    Thus, the correct answer is option A. 
  • Question 5
    1 / -0
    Forest is rich source of:
    Solution
    Forest is a natural resource. It helps in maintaining the ecosystem. It is a rich source of oxygen. Trees absorb carbon dioxide from the atmosphere during photosynthesis and release oxygen into the atmosphere in turn. Hence, forests act as a carbon dioxide sink. 
    Thus, the correct answer is option B. 
  • Question 6
    1 / -0
    Which of the following natural disaster can be prevented by forest?
    Solution
    Drought is a continuous period of dry weather due to abnormally low rainfall. Flood is an overflow of water that submerges land. Global warming is the increase of earth's temperature due to the effect of greenhouse gases which are produced by burning of fossil fuels or deforestation. All these calamities can be prevented by forestation. Forests play an important an important role in climate change. Forests absorbs excess rain water after heavy rains and also it acts as barrier for flood water. Roots of trees hold the water and thus help in drought condition. Tree absorbs carbon dioxide, major greenhouse gas from atmosphere and helps cool down the atmosphere.
    Thus, the correct answer is option D.
  • Question 7
    1 / -0
    The collection of rainwater in the storage tank for reuse can be termed as
    Solution
    Rainwater harvesting is the reuse of water. The term 'rainwater harvesting' refers to the collection of precipitation running off roof surfaces into cisterns or other storage vessels. It also includes the collection of runoff from catchment surfaces (e.g. roads, parking lots and landscaped areas).
    So, the correct answer is 'Water harvesting'.
  • Question 8
    1 / -0
    Which one of the following is not responsible for water shortage ?
    Solution
    • Water is one of the most valuable resources on Earth. Rainwater fills reservoirs that supply drinking water, provide a habitat for fish to live, and nourishes the soil with water necessary for vegetation.
    • Hence Heavy rainfall is not responsible for water shortage.
    • So, the correct answer is 'Heavy rainfall'.
  • Question 9
    1 / -0
    Which of the following is the benefit of water harvesting?
    Solution
    Water harvesting not only increases the production and income of the watershed community, but also mitigates droughts and floods and increases the life of the downstream dam and reservoirs. This water could be used for irrigation and domestic purposes, while the ground water level also increases.
    Thus, the correct option is 'All of the above'.
  • Question 10
    1 / -0
    Efficient water harvesting may lead to 
    Solution
    The collection, sorting and reusing of water is called water harvesting. It can lead to reduction in wastage of water and water scarcity while providing better irrigation facilities.
    The correct option is 'All of the above'.
