Useful Fossil Fuels as Fuel Sources

There are several useful fossil fuels that are commonly used as fuel sources. Some of the correct options include:

1. Coal: Coal is a combustible black or brownish-black sedimentary rock that is primarily composed of carbon. It is one of the most widely used fossil fuels for electricity generation and industrial processes. Coal is formed from the remains of plants that lived and died millions of years ago. It is mined from underground or surface mines and can be classified into different types based on its carbon content, moisture, and energy content.

2. Natural Gas: Natural gas is a fossil fuel primarily composed of methane (CH4) along with small amounts of other hydrocarbons. It is often found in association with oil deposits and is extracted from underground reservoirs. Natural gas is used for heating, electricity generation, and as a fuel for vehicles. It is considered a cleaner-burning fossil fuel compared to coal and oil, as it produces fewer greenhouse gas emissions when burned.

Please note that the other options mentioned in your question, such as limestone and clay, iron ore and copper pyrite, peat and petroleum products, and aluminum ore and clay, are not commonly used as fuel sources. They have other industrial applications, but they are not primarily used for energy generation or as fuel.
