Explanation: Non-renewable energy sources are those that cannot be replenished within a human timescale. These sources are primarily fossil fuels, which include coal, oil, and natural gas. Fossil fuels are formed from the remains of ancient plants and animals over millions of years. The process of their formation is extremely slow, and once these resources are extracted and used, they cannot be replenished within a human lifetime.
Natural gas and oil are both examples of non-renewable energy sources. Natural gas is a hydrocarbon gas mixture primarily composed of methane, and it is extracted from underground reservoirs. Oil, or petroleum, is a liquid fossil fuel that is also extracted from underground reservoirs. Both of these resources are finite and their extraction and use have significant environmental impacts, including greenhouse gas emissions and pollution.
Renewable energy sources, on the other hand, are those that can be replenished within a human timescale. Examples include solar, wind, hydroelectric, and biomass energy. These sources are sustainable and do not deplete over time. Solar energy is derived from the sun, wind energy from the movement of air, hydroelectric power from the flow of water, and biomass energy from organic matter.
It is important to understand the distinction between renewable and non-renewable energy sources because the use of non-renewable sources has significant environmental and economic implications. The depletion of non-renewable resources can lead to energy crises and environmental degradation, while the transition to renewable energy sources can help mitigate these issues and promote sustainable development.
In summary, the correct answer is (C) Natural Gas and Oil, as these are both non-renewable energy sources formed from ancient organic matter and cannot be replenished within a human timescale.
