Question 1
1 / -0

Find the false statement about the Geothermal power plant from the following statements given below :-

A
Geothermal power plants cannot operate round the clock.

B
The initial cost in setting up this plant will be high.

C
This type of source is renewable.

D
This plant can be set only at the specific locations

Solution

Geothermal plants can operate round the clock because the production of heat inside the earth is a continuous process.
Question 2
1 / -0

Solar energy provides _________.

A
Wind energy

B
Light energy

C
Heat energy

D
All the above

Solution

Solution:
Solar energy uses Sun's energy which is converted to heat energy, light energy or wind energy as per requirement. Solar energy is used for heating for domestic and industrial purpose. It is also used for providing electricity which gives light and wind energy.
Hence option D is correct.
Question 3
1 / -0

The fuel formed by the remnants of marine life is:

A
Petroleum

B
Electricity

C
Biogas

D
Coal
Question 4
1 / -0

Which statement about nuclear fusion is false?

A
Nuclear fusion happens in the sun

B
Nuclear fusion is the joining of the nuclei of atoms

C
Nuclear fusion is currently used to generate electrical energy

D
Nuclear fusion can use hydrogen as fuel.

Solution

Nuclear fusion reactions are not currently used to generate electricity because this process is not based on chain reactions as in nuclear fission. In fact, this process (fusion) requires very high temperature.
Thus option $$(C)$$ is the answer.
Question 5
1 / -0

The fossil fuel,among the following is

A
Petroleum

B
Cow-dung cakes

C
Firewood

D
Agricultural wastes

Solution

Petroleum is an example of fossil fuel. Petroleum was formed from organisms living in the sea. As these organisms died, their bodies settled at the bottom of the sea and got covered with layers of sand and clay. Over millions of years, absence of air, high temperature and high pressure transformed the dead organisms into petroleum and natural gas.
Question 6
1 / -0

The energy possessed by very hot rocks inside the earth is called the _______ energy and is used to generate electricity.

A
Geothermal

B
Nuclear

C
Hydrothermal

D
Thermal

Solution

The molten rocks formed in the deeper hot regions of the earth’s crust are pushed upward and trapped in certain regions called hot spots. When underground water comes in contact with the hot spot, steam is generated. Sometimes hot water from that region finds outlets at the surface. Such outlets are known as hot springs. The steam trapped in rocks is routed through a pipe to a turbine and used to generate electricity.
Question 7
1 / -0

The heat energy from hot rocks present inside the earth is known as

A
Solar energy

B
Wind energy

C
Tidal energy

D
Geothermal energy
Question 8
1 / -0

Which of the following converts sunlight into heat energy?

A
Solar cooker

B
Solar cells

C
Windmill

D
None of these

Solution
Question 9
1 / -0

Which bomb works on the principle of Nuclear fusion ?

A
Atom bomb

B
Hydrogen bomb

C
Neutron bomb

D
Nuclear reactor

Solution

Nuclear fusion is a nuclear reaction in which two or more atomic nuclei at a very high speed and join to form a new type of atomic nucleus. Fusion reactions are high energy reactions in which two lighter atomic nuclei fuse to form a heavier nucleus. This fusion reaction is taking place in hydrogen bomb.
Question 10
1 / -0

Which of the following is an incorrect statement ?

A
To overcome the energy crisis the use of solar cooker must be increased

B
To overcome the energy crisis more amount of non-renewable sources of energy must be used

C
The re-usage of waste material as a source of energy can be done to overcome the energy crisis

D
To overcome the energy crisis water has to be saved

Solution

Non-renewable sources of energy mean they cannot be produced or replaced by natural means at a pace to keep up with the consumption rate. We should not exploit non-renewable sources of energy like petrol, coal, natural gas as they will get depleted someday. So we should use them wisely and switch to renewable sources of energy like solar energy, bio-mass, etc.

So option B is incorrect.
