  1. Renewable and degradable resource

  2. Non-renewable resource

  3. Non-degradable non-maintainable

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The resources which can be replenished again after their consumption are referred as the renewable sources of energy. Water is considered as the renewable form of energy. The water reserves can be replenished by the rainfall. The water resource is degradable form of resource. The contaminants and pollutants from the industries can degrade the quality of the water in the water bodies. 

Thus, the correct answer is option A.

Multiple choice evs - i rules are for everyone damaging the forests deforestation and afforestation protecting our environment sustainability of natural resources adaptations - mangrove swamps, fast flowing rivers and treetops halophiles pollution of soil degradation of land

Which method is most effective in controlling floods?

  1. Digging deep canals

  2. Reforestation

  3. Deforestation

  4. Constructing dams
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Loss of vegetation (deforestation) results in an increased risk of flooding. With natural forest cover, the flood duration should decrease. Reducing the rate of deforestation should improve the incidents and severity of floods. Reforestation and afforestation are two strategies to increase the vegetation cover, that can improve infiltration and interception rates, and thus regulate flood peaks. Reforestation refers to planting trees in areas, where they have been cut down, while afforestation means planting trees, where they have never existed. Dams and reservoirs are effective in controlling floods by reducing peak flows. 

Multiple choice evs - i the environment and us damaging the forests deforestation and afforestation protecting our environment pollution of soil degradation of land

Which  one of the following is not a reason for shortage of usable water?

  1. Over exploitation

  2. Climate change

  3. Deforestation

  4. Decrease in sea level
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Overuse of the water resources will result in the exhaustion of the water supply. The climatic change has resulted in global warming and seasonal variations. There is a decrease in the annual rainfall which was received by a region due to shortening of the seasons. Deforestation has resulted in a decrease in the number of trees which thereby affect the amount of rainfall which was received. There is soil erosion which results in water run off.The decrease in the level of the sea is not a reason for the shortage of usable water. 

Thus, the correct answer is option D. 

Multiple choice commercial applications bioenergy biofuels making biofuels technological and industrial development

Ground water will not be depleted due to

  1. Afforestation

  2. Thermal power plants

  3. Loss of forests, decreased rainfall
