Question

Choose the correct statement.

• A. Sun can be taken as an inexhaustible source of energy.
• B. There is infinite storage of fossil fuel inside the earth.
• C. Hydro and wind energy are a non-polluting sources of energy.
• D. Waste from a nuclear power plant can be easily disposed off.

Answer 1

The correct option is A

Sun can be taken as an inexhaustible source of energy.

The correct option is A.
Explanation of the correct option:

1. Natural resources that are inexhaustible - energy sources that are inexhaustible now will still be around tomorrow.
2. These are endless.
3. Examples include sunlight, water, and air.
4. The amount of solar energy in the natural world is limitless.
5. Because they are made from solar energy.
6. Technically speaking, because every star eventually burns out, the sun isn't an endless source of energy.
7. However, the sun's internal fuel supply will keep it going for a long enough time that it can theoretically be thought of as unstoppable.

Explanation of the incorrect options:
Option B:

1. It takes millions of years for fossil fuels to form, which is an extremely sluggish process.
2. As a result, there are only so many resources that can be used, and they are being depleted by human activities like industrialization, rapid expansion, etc.
3. Fossil fuels are therefore finite natural resources.

Option C:

1. The most common source, which now meets 6.6% of the world's energy needs, is hydroelectric power.
2. Solar energy, tidal energy, wave energy, and wind energy are other non-polluting sources.
3. The majority of non-polluting energy sources have high initial prices but minimal ongoing expenses.

Option D:

1. Nuclear waste disposal still presents several difficulties.
2. Due to its extreme danger, nuclear waste is one of the most challenging types of waste to manage.
3. Eventually, radioactive isotopes decay or dissolve into innocuous substances.
4. Some isotopes decay relatively slowly whereas others do so in hours or even minutes.

Final answer: The correct statement is sun can be taken as an inexhaustible source of energy.
