Fossil Fuels

Fossil fuels are natural resources that are formed from the remains of living organisms over millions of years. They are non-renewable sources of energy that play a crucial role in powering our modern world.

Types of Fossil Fuels

There are three main types of fossil fuels:

• Coal
• Oil (petroleum)
• Natural gas

Formation of Fossil Fuels

Fossil fuels are formed through the following process:

1. Organic matter, such as dead plants and animals, is buried under layers of sediment.
2. Over time, the organic matter is subjected to heat and pressure from the layers above.
3. This process, known as diagenesis, transforms the organic matter into fossil fuels.

Environmental Impact

While fossil fuels have been a major source of energy for human civilization, their use has also led to significant environmental impacts, including air and water pollution, greenhouse gas emissions, and habitat destruction.
