Renewable and Non-Renewable Resources

The video explores natural resources, categorizing them into renewable and non-renewable types. It discusses the importance of managing renewable resources like water, fish, and rubber trees sustainably. Non-renewable resources such as fossil fuels are highlighted for their environmental impact and finite nature. The video also covers renewable energy technologies like solar, wind, and hydropower, emphasizing their sustainability compared to fossil fuels.

What are natural resources?

• Resources that are artificially created

• Only minerals and metals found in the earth

• Substances or materials that occur in nature and can be used by humans

• Man-made materials used by humans

Which of the following is a renewable resource?

• Coal

• Water

• Natural gas

• Iron ore

Why are non-renewable resources considered unsustainable?

• They do not cause any environmental harm

• They are always available in abundance

• They are formed through processes that take thousands to millions of years

• They can be replenished quickly

What is the main disadvantage of using fossil fuels?

• They are renewable

• They are easy to extract

• They do not produce energy

• They create pollution and increase greenhouse gases

How do solar panels generate electricity?

• By burning fossil fuels

• By converting kinetic energy into electrical energy

• By using water flow to generate power

• By transforming radiant energy from the Sun into electrical energy

What is a major limitation of wind energy?

• It is always available

• It can be generated anywhere

• It does not require any equipment

• Its availability is inconsistent

What is a key benefit of using renewable energy sources?

• They are finite and will run out soon

• They are only available in certain regions

• They are more sustainable and environmentally friendly

• They produce more pollution than fossil fuels

What is the primary source of geothermal energy?

• Steam and hot water from within the Earth

• Biomass

• Sunlight

• Wind

Which of the following is a common source of biomass energy?

• Solar panels

• Wind turbines

• Wood and waste

• Hydroelectric dams

Why is it important to use resources responsibly?

• To ensure they are available for future generations

• To deplete them quickly

• Because they are unlimited

• To increase pollution
