C Correct answer
Explanation

Natural Resources or Earth resources are those living and non living components of atmosphere, hydrosphere and lithosphere, which can be drawn for supporting life or have potential of being used by humans for their requirements of food, fodder, shelter, clothing, articles of use and recreation.

Inexhaustible resource is a natural resource, which is found in such abundance, that it is unlikely to diminish or get exhausted. E.g., air, solar energy, wind power, rainfall etc.
Exhaustible resource is a natural resource, which is likely to diminish and get exhausted due to continuous use or exploitation. E.g., minerals, fossil fuels, forests etc. Exhaustible resources are of two types renewable and non-renewable.

Which of the following is a non - renewable energy source?

  1. Hydropower

  2. Tidal power

  3. Geothermal energy

  4. Nuclear energy
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Energy sources are of two categories, renewable and non renewable. 

Non renewable resources include fossil fuels (petroleum, natural gas, coal) and nuclear fuel (mostly uranium, which is in limited supply). Use of both of them causes pollution. Fossil fuel cause oil spills, acid rain, air pollution, water pollution etc. Nuclear energy may give rise to radiation pollution. 
Renewable resources of energy include biomass energy and some forms of inexhaustible energy like solar energy, hydro power, wind power etc. They are less polluting but far more expensive due to technological incipiency.

A renewable exhaustible natural resource is

  1. Forest

  2. Coal

  3. Petroleum

  4. Minerals
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Forests are the renewable natural resources which can be recycled but should not be used beyond a limit. Coal, petroleum and minerals are exhaustible resources and cannot be recycled. 

Thus, the correct answer is option A.

Which one of the following is a renewable source of energy?

  1. Petroleum

  2. Coal

  3. Nuclear fuel

  4. Trees
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Renewable energy is defined as energy, that comes from resources, which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat. Trees are very important for us as a renewable energy resource. Trees are a natural resource, that can be renewed - by the planting of trees - replacing the trees, that are harvested for use by people.

Deforestation leads to

  1. Soil erosion

  2. Global warming

  3. Soil protection

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Deforestation is removal or deterioration of forest cover of an area. It results in shirking fuelwood, reduced timber, change in climate, soil erosion, flash floods, siltation, drought, loss of biodiversity, less rainfall, global warming etc.

Thus, the correct answer is option D.

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.

Deforestation may reduce the chances of

  1. Rainfall

  2. Frequent cyclones

  3. Erosion of surface soil

  4. Frequent land slides
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Deforestation is the process of cutting or removal of forest to fulfill the need of the population. It has many negative impacts on the environment such as loss of species, soil erosion and reduces rainfall. The tree absorbs water from soil for photosynthesis and produces water vapor that is released into the atmosphere which in turn causes rainfall. If there will be less number of the tree then rainfall will also decrease. Thus, the correct answer is option A.
