Fossil fuels are energy sources formed over millions of years from the remains of plants, animals, and other living organisms. They are the most abundant form of energy sources on Earth and are still the world’s primary energy source today, accounting for more than 80 percent of the world’s energy consumption. Examples of fossil fuels include coal, oil, and natural gas.
Fossil Fuels Definition
The definition of fossil fuels is any combustible material, such as coal, petroleum, or natural gas, that is derived from the remains of ancient plants and animals. Fossil fuels are created when buried organic materials, such as dead plants and animals, are transformed by heat and pressure over millions of years. This process, known as fossilization, creates a variety of energy sources that are used to power homes and industries worldwide.
Fossil fuels are formed in a variety of ways. Coal, for example, forms over thousands of years when dead plants are buried in layers of sediment. The heat and pressure of being buried deep beneath the Earth’s surface cause the plants to break down and form a new, combustible material. Oil and natural gas, on the other hand, are created when plant and animal matter are exposed to extreme heat and pressure deep in the Earth’s crust. Over millions of years, these materials break down and form oil and natural gas.
Fossil Fuel Examples
The most common examples of fossil fuels are coal, oil, and natural gas. Coal is a combustible black or brownish-black sedimentary rock that is composed of carbon, hydrogen, oxygen, and other elements. It is used to generate electricity and is the most abundant fossil fuel on Earth. Oil is a liquid fossil fuel composed of hydrocarbons and other organic materials. It is used to create a variety of products, such as gasoline, plastics, and solvents.
Natural gas is a fossil fuel composed primarily of methane. It is used to generate electricity, heat homes, and power vehicles. It is also used to produce a variety of chemicals, such as propane and butane. Other examples of fossil fuels include tar sands and oil shale, which are sedimentary rocks containing large amounts of hydrocarbons.
Fossil Fuels in AP Human Geography
The use of fossil fuels has been an integral part of human history. Fossil fuels are used to power homes and industries around the world, providing energy that is essential for economic growth and development. In AP Human Geography, students learn how fossil fuels have shaped the world’s economy, politics, and culture.
In AP Human Geography, students explore how the distribution of fossil fuels has impacted the global economy. They learn how different countries have harnessed the power of fossil fuels to fuel their economies, and how the unequal distribution of resources has led to geopolitical tensions. Students also examine how the use of fossil fuels has contributed to global warming and climate change.
Fossil Fuels and the Environment
The use of fossil fuels has had a profound impact on the environment. Burning fossil fuels releases greenhouse gases, such as carbon dioxide and methane, into the atmosphere. These gases trap heat and raise global temperatures, leading to climate change and other environmental issues. Additionally, the extraction of fossil fuels can have a devastating effect on the environment, including deforestation and the destruction of habitats.
In AP Human Geography, students learn about the environmental impacts of fossil fuel use and explore ways to reduce their dependence on these energy sources. They also investigate renewable energy sources, such as solar, wind, and geothermal power, as alternatives to fossil fuels.

In AP Human Geography, students learn how fossil fuels have shaped the world’s economy, politics, and culture, as well as their environmental impacts. While fossil fuels are still the world’s primary energy source today, renewable energy sources such as solar, wind, and geothermal power are growing in popularity as alternatives to fossil fuels.
