Based on ownership the resources are classified as

• Individual: Resources owned by an individual. Example-land owned by a farmer.
  
• Community: Resources owned by a community. Example-graveyard
  
• National resources: Resources owned by a nations government. Examples-roads, railways etc.
  
• International Resources: Resources regulate by International bodies like oceans and seas.
  

Among the given options all the sources are classified based on the ownership except renewable resources which is type of classification based on the availability.

• Resources are assets that are used by the living systems for the survival and development.
  
• Based on the availability, resources are classified as renewable and non-renewable.
  
• Non-renewable: these are the sources that cannot be renewed and available in limited quantities. Examples include coal, nuclear, oil, and natural gas.
  

Based on the availability, resources are classified as renewable and non-renewable.

Non-renewable: these are the sources that cannot be renewed and available in limited quantities. Examples include coal, nuclear, oil, and natural gas

Example of a non-renewable energy source from the following is minerals

• Balancing the need to use resources and also conserve them for the future is called Sustainable development.
  
• Sustainable development is the process of utilizing natural resources for human development without completely depleting them but by sustaining the ability of nature to continue to provide this resources.
  

Indiscriminate exploitation of resources has led to global ecological crises such as ozone layer depletion, global warming, and environmental pollution.

• Ozone layer depletion: Ozone a blanket of gases which protects earth from reaching of harmful UV rays from the sun. This layer is depleted due to environmental pollution caused by substances like Chlorofluorocarbons etc.
  
• Global warming: It is the heating up of earth’s surface due to some pollutants obstructing heat from escaping the earth’s surface.
  
• Environmental pollution: Any change in the normal environment which has a destructive effect on life is called environmental pollution.
  

• Resource planning is a complex process which identifies present and future resources and their needs.
  
• It involves surveying, mapping and qualitative and quantitative estimation of resources.
  
• The first step of resource planning is identifying the resources present in a region.
  

Tidal energy is converting the energy of tides into more useful form of energy/power for eg Electricity. It functions under water. Since it could be renewed or used again and again it is of the replenish-able type.

Based on the availability, resources are classified as renewable and non-renewable.

Non-renewable: these are the sources that cannot be renewed and available in limited quantities. Examples include coal, nuclear, oil, and natural gas

Iron is a non-renewable source of energy

Chipko movement was a forest conservation movement in India. It began in 1973. Alalknandha floods alarmed people of how deforestation has resulted in disturbance. Thus they took up this movement and carried on a number of rallies to create awareness among people. They protested against commercial logging operations. And finally deforestation was prevented.
