Correct Option
The correct option is (c) 1 and 3 only.
Explanation
Natural resources are materials found in nature that are useful to humans. A fundamental classification of these resources is based on their renewability or exhaustibility-specifically, the rate at which they are replenished relative to their consumption.
Statement-wise Analysis
- Statement 1 is Correct: Natural resources are scientifically classified based on their renewability. They are categorized into renewable resources (which replenish quickly) and non-renewable resources (which have limited stock and take geological timeframes to form).
- Statement 2 is Incorrect: Solar energy is a renewable resource. It is derived from the sun and is considered inexhaustible because it is continuously available and does not deplete with use.
- Statement 3 is Correct: Coal is a non-renewable resource. It is a fossil fuel formed from the remains of ancient vegetation over millions of years. Since its formation takes place over geological time scales, it cannot be replenished within a human lifespan once consumed.
Key Takeaway
Renewable resources (e.g., solar, wind, water) are unlimited or replenish quickly, whereas non-renewable resources (e.g., coal, petroleum, natural gas) are finite and exhaustible due to the extensive time required for their formation.
