Inexhaustible natural resource among the following is

Question

Accepted Answer

Option 4, Sunlight, is the correct answer because it is an inexhaustible natural resource. Sunlight is considered inexhaustible because it is continuously available and is not depleted by human use. The sun emits energy in the form of sunlight, which reaches the Earth every day. This energy is vast and will continue to be available for billions of years, making it a sustainable and renewable resource. Unlike other resources, sunlight does not diminish with use, and its availability is not affected by human consumption.

Now, let's explain why the other options are incorrect:

1. **Forest**: Forests are renewable resources, but they are not inexhaustible. They can be depleted if not managed sustainably. Deforestation and over-exploitation can lead to the loss of forest resources. While forests can regenerate over time, they require careful management to ensure their sustainability.

2. **Coal**: Coal is a fossil fuel and is considered a non-renewable resource. It forms over millions of years from the remains of ancient plants and animals. Once extracted and used, coal cannot be replenished on a human timescale. Therefore, it is exhaustible and will eventually run out if consumed continuously.

3. **Natural gas**: Like coal, natural gas is a fossil fuel and is non-renewable. It is formed from the remains of ancient marine organisms over millions of years. Natural gas reserves are finite and will be depleted with continuous extraction and use. It is not replenished naturally at a rate that can sustain its consumption, making it an exhaustible resource.

In summary, sunlight is the only option among the given choices that is truly inexhaustible, as it is continuously available and not depleted by human use.
