Explanations:Energy sources can be broadly classified into two categories: renewable and non-renewable. Renewable energy sources are those that can be replenished naturally within a human timescale, such as solar, wind, hydroelectric, and biomass. These sources are sustainable and do not deplete the Earth's natural resources. On the other hand, non-renewable energy sources are those that cannot be replenished within a human timescale and are finite in nature. These include fossil fuels like coal, oil, and natural gas, which are formed from the remains of ancient plants and animals over millions of years.
Non-renewable energy sources are characterized by their limited availability and the fact that they take an extremely long time to form. Once these resources are extracted and used, they cannot be replaced in a short period. This makes them finite and depletable. The extraction and use of non-renewable energy sources also have significant environmental impacts, including air pollution, greenhouse gas emissions, and the potential for environmental degradation.
Understanding the distinction between renewable and non-renewable energy sources is crucial for addressing issues related to energy sustainability and environmental conservation. Renewable energy sources are increasingly being promoted as alternatives to non-renewable sources to reduce dependence on finite resources and mitigate the environmental impacts associated with their use.
In the context of the given question, the correct answer is "Natural Gas and Oil" because both are non-renewable energy sources. Natural gas is a fossil fuel composed primarily of methane, and it is formed from the remains of ancient plants and animals over millions of years. Similarly, oil, also known as petroleum, is a liquid fossil fuel that is extracted from underground reservoirs and is formed from the remains of ancient marine organisms. Both of these sources are finite and cannot be replenished within a human timescale, making them non-renewable.
