Energy Resources and Storage Questions

Multiple choice physics sources of energy wave energy tidal energy wave power and tidal power

Waves are used to rotate ____________ to generate electricity. Fill in the gap.

  1. Rotor of Dynamo

  2. Turbine of dam

  3. Wheel of wind mill

  4. Armature of motor
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Waves are made to fall from a height on to the rotor of a turbine or dynamo to make them rotate. This mechanical energy is then converted to electrical energy.

Multiple choice physics sources of energy wave energy tidal energy wave power and tidal power

The two different ways of harnessing energy from ocean are :

  1. Tidal Wave, OTEC

  2. Geothermal, wave energy device

  3. Solar energy, point wave absorber

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The two different ways of harnessing energy from ocean is Tidal wave and Ocean Thermal Energy Conversion (OTEC).
Answer (A) Tidal Wave, OTEC

Multiple choice physics sources of energy wave energy tidal energy wave power and tidal power

Tidal energy is a major source of energy due to the presence of large water bodies on the earth.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

While tidal energy is a source of energy, it is not considered a 'major' source compared to other renewables due to limited suitable sites and high infrastructure costs.

Multiple choice physics sources of energy wave energy tidal energy wave power and tidal power

_________ are used to produce energy in OTEC.

  1. Tidal energy

  2. Temperature difference between the different layers of water in ocean

  3. Ocean waves

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

OTEC stands for Ocean Thermal Energy Conversion, which specifically uses the temperature gradient between surface and deep ocean layers to generate electricity.

Multiple choice physics sources of energy wave energy tidal energy wave power and tidal power

Which of the following is not a form of oceanic energy?

  1. Energy from biomass

  2. Tidal energy

  3. Ocean thermal energy

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

Solar energy is a primary source of energy that drives other processes, but it is not classified as a form of oceanic energy itself, unlike tidal, wave, or thermal energy.

Multiple choice zoology adaptation terrestrial adaptation in animals terrestrial adaptations animal adaptations terrestrial adaptations in plants adaptation in terrestrial plants

What are examples of unsubsidized natural solar powered ecosystem?

  1. Machines

  2. Forests, Oceans and Grasslands

  3. Houses

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

Natural ecosystems like forests, oceans, and grasslands operate using solar energy without human-made subsidies like fertilizers or fuel. Machines, houses, and industries are human-made and require external energy inputs.

Multiple choice commercial applications receding water table water and ocean conservation water resources and conservation water conservation and irrigation

An exhaustible renewable resource is

  1. Coal

  2. Solar energy

  3. Water

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

Natural resources are of two types, exhaustible and non-exhaustible. Exhaustible resources are those natural resources that are available in limited quantity. Examples include coal, natural gas, petroleum. Non-exhaustible resources are those natural resources that are available in abundance. Renewable resources are those which can be recycled or replenished. The solar energy is renewable and non-exhaustible source. Water is a renewable but exhaustible resource. It may exhaust one day if used without any concern. 

Thus, the correct answer is 'Water.'

Multiple choice biology human influences on the environment human intervention in ecosystems humans in the environment involvement of humans in the conservation of environment

What is auxiliary energy in man subsidized solar powered ecosystem?

  1. Man and Machine

  2. wind and Rain

  3. Organic matter

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

In a man-subsidized solar-powered ecosystem, human labor and machinery provide the auxiliary energy needed to increase productivity beyond what natural solar energy alone could support.

Multiple choice biology physical resources air as a natural resource types of chemical reactions chemical reactions

Which of the following are the uses of air?

  1. Generating electricity

  2. Disposal of seeds

  3. Flying of birds

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Air is a mixture of different types of gases, dust particles, water vapours, etc.
The important components of air are nitrogen, oxygen, argon, carbon dioxide, etc,

Air is a very important component of the earth because of the following reasons:

  1. The windmill is designed to harness electricity from the wind, so it can be used for the generated electricity.
  2. Air helps in the process of pollination or seeds disposal.
  3. It helps the birds to fly.

Hence, the correct option is $\text{D}$

Multiple choice geography amazing energy energy and uses energy and its different forms energy

 Sum of potential energy and kinetic energy is called ______________.

  1. mechanical energy

  2. muscular energy

  3. solar energy

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

Sum of potential energy and kinetic energy is called Mechanical energy.
The mechanical energy of an object can be the result of its motion (i.e., kinetic energy) and/or the result of its stored energy of position (i.e., potential energy). The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy.

________________  is obtained from the organic waste.

  1. Nuclear energy

  2. Solar energy

  3. Bio-gas

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

Bio-gas is obtained from the organic waste.
Organic wastes are often disposed of with other wastes in landfills or incinerators, but since they are biodegradable , some organic wastes are suitable for composting and land application. Organic materials found in municipal solid waste include food, paper, wood, sewage sludge , and yard waste .

Which of the following is not the non-conventional sources of energy in India?

  1. Solar Energy

  2. Geo-Thermal Energy

  3. Thermal Energy

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

Thermal energy is not the non-conventional source of energy in India.
Thermal energy comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature. Heat energy is another name for thermal energy. Kinetic energy is the energy of a moving object. As thermal energy comes from moving particles, it is a form of kinetic energy.
