Which of the following is a renewable resource?

evs - i rules are for everyone natural resources and their types promotion of renewable resources protecting our environment sustainability of natural resources adaptations - mangrove swamps, fast flowing rivers and treetops halophiles

  1. Fossil fire

  2. Metal

  3. Water

  4. All of the above

Show answer
Correct Option: C
Explanation:

Inexhaustible resource is a natural resource, which is found in such abundance, that it is unlikely to diminish or get exhausted. E.g., air, solar energy, wind power, rainfall etc.
Exhaustible resource is a natural resource, which is likely to diminish and get exhausted due to continuous use or exploitation. E.g., minerals, fossil fuels, forests etc. Exhaustible resources are of two types renewable and non-renewable.
Renewable exhaustible resource is a natural resource, which gets replenished, recycled or reproduced. E.g., forests, water, agriculture etc.
Non-Renewable exhaustible resource is a natural resource, which is likely to get exhausted with use. E.g., fossil fuels like petroleum, minerals and metals, Coal.

Which of the following is a non - renewable energy source?

evs - i rules are for everyone natural resources and their types promotion of renewable resources protecting our environment sustainability of natural resources adaptations - mangrove swamps, fast flowing rivers and treetops halophiles

  1. Hydropower

  2. Tidal power

  3. Geothermal energy

  4. Nuclear energy

Show answer
Correct Option: D
Explanation:

Energy sources are of two categories, renewable and non renewable. 

Non renewable resources include fossil fuels (petroleum, natural gas, coal) and nuclear fuel (mostly uranium, which is in limited supply). Use of both of them causes pollution. Fossil fuel cause oil spills, acid rain, air pollution, water pollution etc. Nuclear energy may give rise to radiation pollution. 
Renewable resources of energy include biomass energy and some forms of inexhaustible energy like solar energy, hydro power, wind power etc. They are less polluting but far more expensive due to technological incipiency.

A renewable exhaustible natural resource is

  1. Forest

  2. Coal

  3. Petroleum

  4. Minerals

Show answer
Correct Option: A
Explanation:

Forests are the renewable natural resources which can be recycled but should not be used beyond a limit. Coal, petroleum and minerals are exhaustible resources and cannot be recycled. 

Thus, the correct answer is option A. 

Petroleum is a

  1. Non-renewable source

  2. Renewable source

  3. A synthetic product

  4. An inconvenient source

Which one is a non-renewable resource ?

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

  1. Coal and minerals

  2. Plants and coal

  3. Water and natural gas

  4. Energy and water

Show answer
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

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

  1. Non-renewable resources

  2. Inexhaustible resources

  3. Renewable

  4. None of the above

Show answer
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

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

  1. Wood

  2. Biogas/Solar Energy

  3. Coal

  4. Petroleum

Show answer
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

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

  1. Renewable source of energy

  2. Source of alcohol

  3. Source of biogas

  4. Source of petroleum gas

Show answer
Correct Option: A

A non-renewable resource is

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

  1. Soil fertility

  2. Rainfall

  3. Biological species

  4. Wildlife

Show answer
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'.
