MCQ Class 10 Science Sources of Energy with Answers - Set - 3
Question 1:Â
Thermal power plant is considered as a bad source of energy. Why?
(a) as it uses very less amount of fossil fuels
(b) as burning of fossil fuel releases harmful gases
(c) as electricity is harmful and pollutes the environment
(d) as thermal power plants produce less amount of electricity
Correct Answer – (B)
Question 2 :Â
Ramesh studies that due to gravitational pull, the level of water in the sea rises and falls.
With the advancement of technology, generation of electricity has been made possible. This type of energy is known as tidal energy. Should tidal energy be considered a conventional or nonconventional source of energy?
(a) conventional, as it uses water as source of energy
(b) non-conventional, as gravitational energy is converted to electrical energy
(c) conventional, as the resulted product is electricity which can be used as fuel
(d) non-conventional, as extraction of this energy is possible with advance in technology
Correct Answer – (D)
Question 3 :Â
Which of these processes explains the extraction of energy from wind to generate energy for a water-lifting pump?
(a) conversion of mechanical energy of wind into kinetic energy
(b) conversion of kinetic energy of wind into mechanical energy
(c) conversion of mechanical energy of wind into potential energy
(d) conversion of potential energy of wind into mechanical energy
Correct Answer – (B)
Question 4 :Â
A student studies that biogas contains a large amount of methane which can be used as
a fuel for various uses. It burns without releasing smoke and leaving no residue like ash in other
fossil fuel. Should biomass be considered a ‘good’ or ‘bad’ source of energy?
(a) bad, as it does not release smoke
(b) good, as it produces methane gas
(c) bad, as it burns without releasing smoke
(d) good, as it does not cause any harm to the environment
Correct Answer – (D)
Question 5 :Â
Which process explains the energy extraction from a sea wave?
(a) using kinetic energy of the waves to produce electricity
(b) using thermal energy of the waves to produce electricity
(c) using chemical energy of the waves to generate electricity
(d) using electrical energy of the waves to generate electricity
Correct Answer – (A)

Question 6 :Â
A student studies that the efficiency of a fuel can be increased using new technologies. How does increased efficiency benefit humans and the environment?
(a) production of fuel will increase
(b) cost of fuel production will decrease
(c) amount of fuel in reservoirs will increase
(d) pollution and consumption will decrease
Correct Answer – (D)
Question 7 :Â
Why is biogas considered as a ‘good’ source of energy?
(a) as it produces ashes
(b) as it produces methane
(c) as it burns without releasing smoke
(d) as it decomposes in the absence of oxygen
Correct Answer – (C)
Question 8 :Â
A student wants to extract energy from fossil fuel. Which process would help him to extract the energy from fossil fuel?
(a) burning
(b) crystallization
(c) condensation
(d) distillation
Correct Answer – (A)
Question 9 :Â
Why is wind energy considered as a conventional source of energy?
(a) as it can rotate a windmill
(b) as it can help in lifting water
(c) as it is readily available and used for a long time
(d) as it produced due to uneven heating of the Earth
Correct Answer – (C)
