Questions Related to solar energy

The term Black gold is used for:

evs solar energy fuels and fossil fuels solar energy and its applications electric energy generation and environment

  1. coal

  2. petroleum

  3. graphite

  4. charcoal

Show answer
Correct Option: B
Explanation:

Oil and petroleum are referred to as black gold. When extracted, it is black in colour, however, its market value is very high like gold.

  4. Solar

Show answer
Correct Option: A,B
Explanation:

Conventional sources : wood, coal, fossil fuels.

Non-conventional sources: wind, thermal, solar, tidal.

Which of the following is NOT a fossil fuel?

evs solar energy fuels and fossil fuels solar energy and its applications electric energy generation and environment

  1. Wood

  2. Coal

  3. Petroleum

  4. Natural gas

Show answer
Correct Option: A
Explanation:

Fuels formed due to the decomposition of dead animals and organic matter mainly in an anaerobic condition millions of years ago are fossil fuels. Coal, natural gas and petroleum are fossil fuels.

From below conventional sources of energy which is NOT a non renewable source of energy?

evs solar energy fuels and fossil fuels solar energy and its applications electric energy generation and environment

  1. Wind

  2. Coal

  3. Petroleum

  4. Natural gas

Show answer
Correct Option: A
Explanation:

Some examples of conventional sources of energy are wood, coal, fossil fuels, petroleum and natural gas.

Some examples of non-conventional sources of energy are wind, hydel, solar, tidal.

Conventional sources of energy are also known as :

evs solar energy fuels and fossil fuels solar energy and its applications electric energy generation and environment

  1. Non Renewable sources

  2. Renewable sources

  3. Both a and b

  4. None

Show answer
Correct Option: A
Explanation:

Sources of energy that have been used for a very long time and cannot be used or renewed again are the conventional sources of energy. Example: coal, oil and pertroleum.

Which of the following energy source is most costly?

evs solar energy fuels and fossil fuels solar energy and its applications electric energy generation and environment

  1. Thermal Energy

  2. Hydel Energy

  3. Solar Energy

  4. Fossil Energy

Show answer
Correct Option: B
Explanation:

Harnessing hydel power / energy is very costly procedure due to construction of large dams across the streams, clearance of vegetation for the development of the project, rehabilitation of the people living nearby the water bodies.

Of the following, the fuel different from others is

  1. Diesel

  2. Gasoline

  3. Alcohol

  4. Lignite

Show answer
Correct Option: D

Coal is formed from the remains of :

evs solar energy fuels and fossil fuels solar energy and its applications electric energy generation and environment

  1. vegetation only

  2. both vegetation and animals

  3. animals only

  4. none of these

Show answer
Correct Option: A

Coal and petroleum are called fossil fuels.      

evs solar energy renewable and non-renewable resources renewable and non-renewable sources of energy substances, objects and energy solar power plant production of electricity from solar energy solar energy and its applications

  1. True

  2. False

  3. Ambiguous

  4. Data insufficient

Show answer
Correct Option: A
Explanation:

Answer is A.

It is because they are actually fossils. They are made of dead and decay matter buried under the earth for many years. The dead and decaying matter under great amount of pressure and temperatures turn into fossils and they both are used as fuels so it is called fossil fuels.
The fossil fuels we use today are actually formed from plants and animals that existed hundreds of millions of years ago. The reason there is a lot of concern surrounding the expenditure of these resources is because most of what we use today from fossil fuels, such as oil and coal are being depleted much faster than they can be formed, so there is a limited amount available.
Hence, the statement is true.

The fossil fuels include:

evs solar energy renewable and non-renewable resources renewable and non-renewable sources of energy substances, objects and energy solar power plant production of electricity from solar energy solar energy and its applications

  1. Uranium

  2. Soil

  3. Natural gas

  4. Plants

Show answer
Correct Option: C
Explanation:

Fossil fuels are formed when plants and marine species are buried below ground and are subjected to immense pressure and temperature for thousands of years. Examples include coal, petroleum and natural gas.
