Mineral and metals are 

  1. Biodegradable resources

  2. Renewable

  3. Non- renewable

  4. Renewable and non - renewable resources
Reveal answer Fill a bubble to check yourself
C Correct answer
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.

  1. True

  2. False

  3. Nither

  4. Either
Reveal answer Fill a bubble to check yourself
A Correct answer
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'.

The resources that are derived from bio-mass of living organisms are called  ____________ resources.

  1. renewable

  2. non-renewable

  3. environmental

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

Resources derived from biomass, such as plants and animals, are considered renewable because biological processes can regenerate them within a human-relevant timeframe.

Recycling and use of renewable energy, helps in preventing

  1. Acid deposition

  2. Global warming

  3. Resource depletion

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

Recycling materials and utilizing renewable energy sources reduces the demand for raw extraction, thereby preventing the depletion of finite natural resources.

Petroleum resource is

  1. Renewable

  2. Non renewable

  3. Synthetic and biodegradable

  4. Infinite and unconventional
Reveal answer Fill a bubble to check yourself
B Correct answer
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

  1. Alcohol fuel

  2. Petroleum

  3. Biogas

  4. Fuel wood
Reveal answer Fill a bubble to check yourself
B Correct answer
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 one of the following is a renewable source of energy?

  1. Petroleum

  2. Coal

  3. Nuclear fuel

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

Renewable energy is defined as energy, that comes from resources, which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat. Trees are very important for us as a renewable energy resource. Trees are a natural resource, that can be renewed - by the planting of trees - replacing the trees, that are harvested for use by people.

Which is not a renewable source?

  1. Forest

  2. Coal

  3. Water

  4. Wind
Reveal answer Fill a bubble to check yourself
B Correct answer
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?

  1. Wood

  2. Alcohol

  3. Biogas

  4. Coal
Reveal answer Fill a bubble to check yourself
D Correct answer
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.
