Questions Related to water and air and their importance

Which one is a non-renewable resource ?

  1. Coal and minerals

  2. Plants and coal

  3. Water and natural gas

  4. Energy and water


Correct Option: A
Explanation:
  • A nonrenewable resource is a resource of economic value that cannot be readily replaced by natural means on a level equal to its consumption. For example, Most fossil fuels, such as oil, natural gas, and coal and earth metals, minerals.
  • These resources are considered non-renewable because their formation takes billions of years.
  • Hence coal and minerals are examples for the non-renewable resource.
  • So, the correct answer is 'Coal and minerals'.

Metallic minerals and fossil fuels are

  1. Non-renewable resources

  2. Inexhaustible resources

  3. Renewable

  4. None of the above


Correct Option: A
Explanation:

Resources are of two types, renewable and nonrenewable. Renewable resources are those resources that can be renewed and replenished. Nonrenewable resources are those resources that cannot be renewed or replenished. Examples of renewable resources include water, solar, wind. Examples of nonrenewable resources include metallic minerals and fossil fuels. 

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

Non-conventional source of energy is

  1. Wood

  2. Biogas/Solar Energy

  3. Coal

  4. Petroleum


Correct Option: B
Explanation:
  1. Non-conventional sources of Energy. Natural resources like wind, tides, solar, biomass, etc generate energy which is known as “Non-conventional resources.
  2. Solar energy is the most important non-conventional source of energy and it gives non-polluting environment-friendly output and is available in abundant.
  3. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas is a renewable energy source. so, option biogas / solar energy.

Fuel wood is

  1. Renewable source of energy

  2. Source of alcohol

  3. Source of biogas

  4. Source of petroleum gas


Correct Option: A

A non-renewable resource is

  1. Soil fertility

  2. Rainfall

  3. Biological species

  4. Wildlife


Correct Option: C
Explanation:

A non-renewable source of energy is atype of resource which cannot be replenished back or take a very long time to replenish back, so biological species once lost cannot come back.

So, the correct option is 'Biological species'.

Which of the following is a renewable?

  1. Wood

  2. Organic remains

  3. Biogas

  4. All of the above


Correct Option: D
Explanation:
A. Wood is basically secondary xylem formed from secondary growth in the stems of plants. 
B. Organic remains are the mineralized remains of plants and animals.
C. Biogas is produced from the breakdown of organic matter in the absence of oxygen, by the action of microorganisms.
Renewable sources are the ones that can be replenished naturally over a period of time. Wood, organic remains and biogas are replenished naturally. Hence, all these are renewable.
So, the correct answer is 'All of the above'.

Which of the following is a renewable resource?

  1. Fossil fuel

  2. Metals

  3. Sunlight

  4. Both A and B


Correct Option: C
Explanation:

Renewable source of energy can be replenished in a very short period of time, sunlight is the constant and inexhaustible source of energy.

So, the correct answer is 'Sunlight'

An inexhaustible resource is

  1. Wind power

  2. Soil fertility

  3. Wildlife

  4. All the above


Correct Option: A
Explanation:

Since wind energy is a renewable source of energy it is a never ending source thus it is an inexhaustible source.

So, the correct answer is 'Wind power'

A non-renewable and non-inexhaustible resource is

  1. Forest

  2. Coal/Petroleum

  3. Water

  4. Wildlife


Correct Option: B
Explanation:

Coal/petroleum come under the category of non-renewable resource, once finished it cannot be replenished in a short period of time.

So, the correct answer is 'Coal/Petroleum'

Which one of the following is renewable resource ?

  1. Water

  2. Metals

  3. Fossil fuel

  4. All the above


Correct Option: A
Explanation:

Metals & fossil fuels are non- renewable sources because they cannot be replenished in a shorter period of time, while water is a renewable resource.

So, the correct answer is 'Water'
