Question : Assertion: Non-renewable energy sources are finite and deplete over time.
Reason: Non-renewable energy sources are formed over millions of years through geological processes.
Option 1: Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
Option 2: Both assertion and reason are correct, but the reason is not the correct explanation of the assertion.
Option 3: Assertion is correct, but the reason is incorrect.
Option 4: Assertion is incorrect, but the reason is correct.
Correct Answer: Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
Solution : The correct answer is (a) Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
The assertion states that non-renewable energy sources are finite and deplete over time, which is correct. Non-renewable energy sources, such as fossil fuels (coal, oil, and natural gas), are formed over millions of years through geological processes. These sources exist in limited quantities and cannot be replenished within a human lifespan or a short geological timescale. As they are extracted and used, the available reserves of non-renewable energy sources diminish, leading to their depletion over time.
The reason provided states that non-renewable energy sources are formed over millions of years through geological processes, and this is the correct explanation of the assertion. Fossil fuels, for example, are created from the remains of plants and animals that lived millions of years ago. The process of fossilization and the transformation of organic matter into fossil fuels take place over long periods of time involving geological processes, including heat, pressure, and the burial of organic material. This explains why non-renewable energy sources are finite and cannot be replenished within a short timespan.
Therefore, both the assertion and reason are correct, and the reason serves as the correct explanation for why non-renewable energy sources are finite and deplete over time.
Question : Assertion: Non-renewable energy sources, such as fossil fuels, contribute to environmental pollution and greenhouse gas emissions.
Reason: Non-renewable energy sources are finite and take millions of years to form.
Question : Assertion: Non-renewable energy sources are associated with environmental pollution and resource depletion.
Reason: Non-renewable energy sources release pollutants and are limited in quantity.
Question : Assertion: Renewable energy sources, such as solar and wind power, play a crucial role in reducing carbon emissions and mitigating climate change.
Reason: Renewable energy sources are abundant, sustainable, and do not deplete natural resources.
Question : Assertion: Renewable energy sources are considered sustainable because they can be naturally replenished.
Reason: Renewable energy sources harness natural processes such as sunlight, wind, and water.
Question : Assertion: Commercial energy sources are widely used for industrial production and transportation.
Reason: Commercial energy sources are more cost-effective and have higher energy density compared to non-commercial sources.
