Fossil Fuels

Fossil fuels are natural resources that are formed from the remains of ancient plants and animals. Over millions of years, the remains are transformed by heat and pressure into coal, oil, and natural gas. These fuels are non-renewable, meaning they cannot be easily replaced once they are used up.

Types of Fossil Fuels:

• Coal: Formed from the remains of plants that lived in swamps millions of years ago. There are different types of coal, including lignite, bituminous, and anthracite.
• Oil (Petroleum): Formed from the remains of marine plants and animals. It is found in underground reservoirs and is extracted through drilling.
• Natural Gas: Formed from the same type of organic material as oil, but it is in the gaseous state at room temperature. It is often found in association with oil deposits.

Uses of Fossil Fuels:

Fossil fuels are used for a variety of purposes, including:

• Electricity generation
• Transportation (e.g., gasoline and diesel for cars, trucks, and airplanes)
• Heating and cooling buildings
• Manufacturing processes

Environmental Impact:

While fossil fuels have been essential for human development, their use has also led to environmental issues such as air and water pollution, greenhouse gas emissions, and habitat destruction.
