Which of these natural resources is considered as non-renewable resource?

The Correct answer is Option 2 

Key Points

Fossil Fuels:

• Fossil Fuels (like coal, oil, and natural gas) are considered non-renewable resources because they take millions of years to form, and once used, they cannot be replenished within a human timescale. Their consumption leads to depletion, and they are finite in nature.

• Timber: While it can be renewable if managed sustainably (i.e., through replanting and sustainable forestry practices), it can be non-renewable if forests are overharvested without proper management.

• Solar Energy: This is a renewable resource as the energy from the sun is abundant and continuously replenished.
• Wind Energy: Also a renewable resource, as the wind is a natural, sustainable force that doesn't deplete when used to generate electricity.
• Thus, fossil fuels are the only non-renewable resource in the given options.
