Energy Resources and Storage Questions

Multiple choice commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

Renewable exhaustible natural resource of energy is

  1. Biomass/ forest

  2. Coal

  3. Petroleum

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

Renewable source of energy is a type of resource which can be replenished back easily. Coal, petroleum, kerosene will take millions of years to replenish back so, they are non-renewable source of energy.

So, the correct answer is 'Biomass/ forest'

Multiple choice commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

Minerals, metals and fossil fuels are which type of resources of energy? 

  1. Renewable

  2. Non-renewable

  3. Biodegradable

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

A non-renewable resource (also called as finite resource) is a resource, that does not renew itself at a sufficient rate for sustainable economic extraction. Non-renewable resources are resources, that are not easily replenished by the environment. Earth minerals and metal ores, fossil fuels (such as coal, petroleum, and natural gas), nuclear fuels, and groundwater in certain aquifers are all non-renewable resources.

Multiple choice zoology meaning of life energy flow and loss energy flow in a food chain energy flows

The best source of energy in the environment is

  1. Water

  2. Soil

  3. Trees

  4. Ponds
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Trees are autotrophs or producers in an ecosystem and trap solar energy. The solar energy is converted into chemical energy, which is stored in seeds, fruits and other storage organs. Thus, producers like trees are the source of chemical energy for all the heterotrophic organisms. All the heterotrophs either directly or indirectly depend on the food, synthesized by producers like trees. These organisms directly cannot use solar energy.

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

If we remove half of the forest cover of earth, what kind of crisis will occur?

  1. Many species would become extinct.

  2. Population, pollution and ecological imbalance will rise.

  3. Energy crisis will commence.

  4. The remaining forest will cause imbalance.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Forests occupy more than 30 percent of Earth's land surface and account for 50 percent of plant productivity. Therefore 45% of the carbon stored on land is tied up in forests. Further, these being the dominant terrestrial ecosystem, the forest account for 75% of the gross primary productivity of the Earth's biosphere and 80% of the plant biomass. Removing half the forest cover, will not only bring in an increase in the population of human beings and other living organisms but will also bring about increased pollution and a great ecological imbalance.

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

Which of the following is the most important conventional natural source of energy?

  1. Atomic energy

  2. Biogas

  3. Sunlight

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

Conventional source of energy is a type of source which is limited in nature like coal, gas, fuel, minerals etc. they take millions of years to replenish. 

So, the correct answer is 'Fossil fuels'

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

Fossil fuels are 

  1. Conventional resources

  2. Non-conventional resources

  3. Non-renewable resources

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

  • Conventional sources of energy are generally non-renewable sources of energy as the accumulation or creation of conventional sources of energy takes years, once they are exploited or consumed. 
  • Fossil fuels are an example of conventional resources. Petrol, diesel, coal, natural gas, etc are examples of fossil fuels that are obtained by the microbial action on the dead matter for a long time. 
  • They are used as a source of fuel and energy from ancient times and it takes years to form once they are exploited.

Thus, the correct answer is option D.

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

Oil, coal and naturalgas constitute

  1. Renewable source

  2. Fossil fuel

  3. Eontic fuel

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Fossil fuels are the hydrocarbon compounds formed due to the microbial activity on the dead plants and animals. There are different materials which can be referred as the fossil fuels. The coal, natural gas, oil, petrol, diesel are all the components which are obtained from the Earth. These are used as fossil fuels for the production of energy.

Thus, the correct answer is option B. 

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

The energy obtained from biological resources is called as

  1. Electrical energy

  2. Mechanical energy

  3. Bioenergy

  4. Life energy
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, straw, manure, sugarcane, and many other byproducts from a variety of agricultural processes.

Revised data for petroleum depletion time is

  1. 2010

  2. 2020

  3. 2030

  4. 2040
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
With the increased rate of population, the demand for natural energy resources has also increased over a period of time. 
Petroleum is a non-renewable source of energy because it takes thousands of years for the crude oil to be formed in the earth. 
The increasing demand for the use of petroleum is much faster than the rate at which petroleum is produced. 
So, the petroleum in the earth's reservoir is estimated to be finished in next few years by the end of 2030 as per the reports of IEA (International Energy Agency).
So, the correct answer is '2030'

The main source of biomass energy is 

  1. Coal

  2. Heat energy

  3. Thermal energy

  4. Cow-dung
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Organic matter that is obtained from living or dead organisms is called as biomass. Biomass energy is a renewable energy source. Coal, heat energy, and thermal energy are all fossil fuels while biomass is a source of energy available from organic matter like plant and animal wastes.

Thus, the correct answer is option D.

As the water stored in the reservoir of a dam flows out, its potential energy changes to :

  1. magnetic energy

  2. light energy

  3. kinetic energy

  4. heat energy
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation


The potential energy stored in a reservoir at a given height is converted to kinetic energy (movement energy) which is used to turn a turbine and produce electricity.
Hence, as the water stored in the dam flows out, its potential energy changes to kinetic energy.
