Fossil Fuels

Front

What are fossil fuels?

Back

Fossil fuels are natural resources formed from the remains of ancient plants and animals that have been buried and transformed over millions of years. They include coal, oil, and natural gas.

How do fossil fuels form?

Back

Fossil fuels form when organic materials, like decaying plants and animals, are buried under layers of sediment and subjected to heat and pressure over millions of years.

Front

What is coal?

Back

Coal is a type of fossil fuel that is formed from the remains of ancient plants. It is a solid black or brownish-black substance used primarily for electricity generation and steel production.

Front

What is natural gas?

Back

Natural gas is a fossil fuel that is primarily composed of methane. It is found deep beneath the earth's surface and is used for heating, cooking, and electricity generation.

Front

What is petroleum?

Back

Petroleum, also known as crude oil, is a liquid fossil fuel formed from the remains of ancient marine organisms. It is refined into various products, including gasoline and diesel.

Front

What are sedimentary rocks?

Back

Sedimentary rocks are types of rocks formed by the accumulation and compression of mineral and organic particles over time. They often contain fossils.

Front

What is the process of sedimentation?

Back

Sedimentation is the process by which particles settle out of a fluid (like water) and accumulate at the bottom, forming layers of sediment.

Front

What is the significance of marine mud in fossil fuel formation?

Back

Marine mud is significant because it contains the decaying remains of organisms, which, when buried and subjected to heat and pressure, can transform into fossil fuels.

Front

What is the oldest layer in a sedimentary rock formation?

Back

In a sedimentary rock formation, the oldest layer is typically at the bottom, as new layers are deposited on top of older ones.

What is reusing a resource?

Back

Reusing a resource means using the same item multiple times instead of discarding it. For example, using the same drinking glass for water.
