Questions Related to commercial applications

Mineral and metals are 

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

  1. Biodegradable resources

  2. Renewable

  3. Non- renewable

  4. Renewable and non - renewable resources

Show answer
Correct Option: C
Explanation:

Minerals and metals are non renewable sources of energy as depletion in it is not possible to renew again.

Thus, the correct answer is 'Non - renewable.'

The fossil fuels, coal and petroleum, will ultimately be exhauste.

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

  1. True

  2. False

  3. Nither

  4. Either

Show answer
Correct Option: A
Explanation:
The fossil fuels, coal and petroleum will ultimately exhaust because these are non-renewable natural resources. They are not replenished by nature and once used, they are lost forever. It takes a very long time for their formation. Petroleum is produced from crude oil which takes million of years to form in the earth from the dead remains of plants and animals. Similarly, coal and fossil fuels also form in this way in million of years. Hence, they will ultimately get exhausted as the demand for these resources is increasing.
Hence, the statement given in the question is correct.
So, the correct answer is 'True'.

Petroleum resource is

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

  1. Renewable

  2. Non renewable

  3. Synthetic and biodegradable

  4. Infinite and unconventional

Show answer
Correct Option: B
Explanation:

A non-renewable resource is a resource that does not renew itself at a sufficient rate for sustainable economic extraction. They are found in fixed amounts and are being used faster than they can be replenished. An example is carbon-based, organically-derived fuel. The original organic material, with the aid of heat and pressure, becomes a fuel such as oil or gas. 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

So, the correct answer is 'Non renewable'

The example of non-renewable source of energy is

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

  1. Alcohol fuel

  2. Petroleum

  3. Biogas

  4. Fuel wood

Show answer
Correct Option: B
Explanation:

Non-renewable resources are resources for which there is a limited supply. The supply comes from the Earth itself and it typically takes millions of years to develop. Non-renewable resources can generally be separated into two main categories; fossil fuels and nuclear fuels. Fossil fuels are derived from organic matter which has been trapped between layers of sediments within the Earth for millions of years. Crude oil/petroleum is a non-renewable resource that builds up in liquid form between the layers of the Earth's crust. The other form of non-renewable resource used to produce energy, nuclear fuels, is primarily obtained through the mining and refining of uranium ore. Renewable energy includes biomass, wind, hydro-power, geothermal and solar sources. 

Thus, the correct answer is option B.

Which is not a renewable source?

  1. Forest

  2. Coal

  3. Water

  4. Wind

Show answer
Correct Option: B
Explanation:

Renewable resources are resources that are replenished by the environment over relatively short periods of time. Some examples of renewable energy sources are solar energy, wind energy, hydropower, geothermal energy, and biomass energy. Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. This is usually due to the long time it takes for them to be replenished. 

Which one of the following, is not the renewable source of bioenergy?

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

  1. Wood

  2. Alcohol

  3. Biogas

  4. Coal

Show answer
Correct Option: D
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. Most non-renewable energy sources are fossil fuels: coal, petroleum, and natural gas. Carbon is the main element in fossil fuels. 

Thus, the correct answer is option D.

Which of the following is the non conventional source of energy?

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

  1. Coal

  2. Petroleum

  3. Electricity from nuclear power plants

  4. Solar radiations

Show answer
Correct Option: D
Explanation:

Energy generated by using wind, tides, solar, geothermal heat, and biomass including farm and animal waste as well as human excreta is known as non-conventional energy. 

All these sources are renewable or inexhaustible and do not cause environmental pollution. The non-conventional sources of energy are abundant in nature. According to energy experts the non-conventional energy potential of India is estimated at about 95,000 MW.
