Natural gas is a valuable energy source that is formed from the remains of tiny sea plants and animals that died millions of years ago. Over time, the remains were buried under layers of sand and mud, and the heat and pressure from the Earth transformed them into natural gas.

Composition of Natural Gas

Natural gas is primarily composed of methane, which is a simple chemical compound made up of one carbon atom and four hydrogen atoms. In addition to methane, natural gas may also contain small amounts of other hydrocarbons, such as ethane, propane, and butane, as well as non-hydrocarbon gases like carbon dioxide, nitrogen, and hydrogen sulfide.

Extraction and Processing

Natural gas is extracted from the Earth by drilling wells into underground rock formations where the gas is trapped. Once it is brought to the surface, the gas is processed to remove impurities and separate the different hydrocarbons. This processed natural gas is then transported through pipelines to homes, businesses, and other facilities for use as a clean and efficient energy source.

Uses of Natural Gas

Natural gas has a wide range of uses, including:

• Heating homes and businesses
• Generating electricity
• Fueling vehicles
• Providing feedstock for the production of chemicals and plastics

Environmental Impact

When burned, natural gas produces less carbon dioxide and air pollutants compared to other fossil fuels, making it a relatively cleaner option. However, the extraction and transport of natural gas can result in methane emissions, which is a potent greenhouse gas. Efforts are being made to reduce these emissions to minimize the environmental impact of natural gas usage.

Study Guide

Here are some key points to remember about natural gas:

1. Natural gas is primarily composed of methane.
2. It is extracted from underground rock formations through drilling wells.
3. Natural gas is processed to remove impurities and separate different hydrocarbons.
4. It is used for heating, electricity generation, and as a fuel for vehicles.
5. Efforts are being made to reduce methane emissions associated with natural gas production and usage.
