Study Notes
Natural Resources
- Natural resources are materials given to us by nature that can be transformed to become more valuable and useful.
- Examples of natural resources include wood, cotton, metals, water, minerals, forests, wildlife, and human beings.
Classification of Natural Resources
- Based on continuity, natural resources are classified into:
- Renewable Resources
- Non-renewable Resources
- Cyclic Resources
Renewable Resources
- Resources that can be renewed along with their exploitation and are always available for use.
- Examples of renewable resources include:
- Forests (can be maintained through reforestation)
- Solar energy
- Wind energy
- Biomass energy
- Tidal energy
- Hydropower
Non-renewable Resources
- Resources that cannot be regenerated and will eventually deplete.
- Examples of non-renewable resources include:
- Iron ore
- Coal
- Mineral oil
- These resources take thousands of years to form and cannot be easily replaced once used.
Cyclic Resources
- Resources that can be used continuously and cleaned for reuse.
- Example of cyclic resources include:
- Water used in industry and domestic ways can be cleaned and reused.
Importance of Conservation
- It is essential to protect and conserve natural resources and use them judiciously to ensure their availability for future generations.
Types of Energy
- There are three types of energy:
- Non-renewable
- Renewable
- Examples of renewable energy sources include:
- Wind Power
- Water Power
- Ocean energy
- Bio Fuel/Solid Bio Mass
- Geothermal Energy
Geothermal Energy
- Geothermal energy is thermal energy extracted from the Earth's crust.
- It has been used as a source of heat and/or electric power for millennia.
- As of 2019, 13,900 megawatts (MW) of geothermal power was available worldwide.
