Fossil Fuels

Fossil fuels are natural resources such as coal, oil, and natural gas that are formed from the remains of ancient plants and animals. These fuels are non-renewable and are being used at a rapid rate, leading to environmental concerns.

Formation of Fossil Fuels

Fossil fuels are formed from the decomposition of organic matter over millions of years. The process begins with the burial of dead plants and animals under layers of sediment. Over time, heat and pressure from the Earth's crust transform the organic matter into fossil fuels.

Types of Fossil Fuels

1. 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, which vary in their energy content and carbon concentration.

2. Oil: Also known as petroleum, oil is formed from the remains of marine plants and animals. It is found in underground reservoirs and is used to produce gasoline, diesel, and various other products.

3. Natural Gas: Primarily composed of methane, natural gas is formed in a similar manner to oil. It is often found alongside oil deposits and is used for heating, electricity generation, and as a fuel for vehicles.

Extraction and Use of Fossil Fuels

Fossil fuels are extracted through mining (coal), drilling (oil), and fracking (natural gas). Once extracted, they are used to generate electricity, power vehicles, and provide heat for various applications.

Environmental Impact

The burning of fossil fuels releases carbon dioxide and other pollutants into the atmosphere, contributing to climate change and air pollution. Additionally, the extraction and combustion of fossil fuels can lead to habitat destruction, water pollution, and other environmental concerns.
