Question

Difficulty: MediumRenewable and Non-Renewable Natural Resources

Peat and lignite are classified as non-renewable natural resources because their natural rate of formation spans millions of years of geological processes, despite their organic plant origin.

Answer: Answer

Answer

The statement is True. Although derived from biological vegetation, peat and lignite require geological timescales to form, making them non-renewable natural resources.
The statement correctly identifies that resource renewability is determined by the rate of natural replenishment relative to human consumption. Because peat and lignite formation takes millions of years, they are functionally finite non-renewable resources.

Step-by-Step Solution

1
Analyze the formation process and origin of peat and lignite.
Peat and lignite originate from decomposed organic plant matter subjected to gradual pressure and heat over geological epochs.
Resource classification depends on comparing the rate of natural replenishment against the rate of human consumption.
2
Evaluate whether biological origin guarantees renewability.
Organic origin alone does not make a resource renewable if geological transformation time far exceeds human scales.
Renewable resources must naturally restore themselves rapidly enough to match ongoing utilization.
3
Conclude the correct resource category.
Peat and lignite are non-renewable fossil fuel precursors.
Their finite total reserves and multi-million-year formation period place them strictly in the non-renewable category.
