Sustainable

The video tutorial explains the concept of sustainable processes, highlighting that they do not harm the environment or deplete natural resources over time. It contrasts sustainable energy sources like wave and wind power with non-sustainable ones like coal, which is finite and will eventually be exhausted.

What is a key characteristic of a sustainable process?

• It requires constant human intervention.

• It relies on finite resources.

• It can be continued indefinitely without harming the environment.

• It is the most cost-effective method.

Which of the following is considered a sustainable energy source?

• Nuclear power

• Coal

• Wave power

• Natural gas

Why is wind power considered sustainable?

• It is available only in certain regions.

• It does not deplete natural resources.

• It is the cheapest form of energy.

• It requires no maintenance.

What is a major drawback of using coal for energy?

• It is a renewable resource.

• It is a finite resource and will eventually be exhausted.

• It is abundant and will never run out.

• It produces no emissions.

How does burning coal impact sustainability?

• It supports long-term environmental health.

• It contributes to resource depletion.

• It is a clean energy source.

• It enhances biodiversity.
