Lesson 7: Fossil Fuels

It is the remains of long-extinct organisms.

A type of energy source

It is a nonrenewable source of energy created by ancient ecosystems. It provides the majority of the world’s energy.

The first commonly utilized fossil fuel, originates in swampy places. Higher carbon and more flammable; valuable.

One of the 4 stages of Coal: Partially decayed plants, smoky and wet. Very low heat & pressure

One of the 4 stages of Coal: “brown coal”; low energy, crumbly and soft. Low heat & pressure.

One of the 4 stages of Coal: “soft coal”; most common, used for electricity. High heat & pressure.

One of the 4 stages of Coal: “hard coal”; highest energy and burns the cleanest. Very high heat & pressure.

As peat turns lignite, what occurs?

Anthracite is the highest metamorphic grade of coal. But with more heat and pressure driving out all the volatiles and leaving pure carbon, what does it turn to?

Petroleum is made out of?

Petroleum’s liquid component is called:

The gas component of petroleum is called and is made up of:

What is carried to the seafloor so rapidly in regions with strong marine productivity that part of it escapes oxidation?

What then does the organic matter within the sediments eventually turn into?

The first stage of biological synthesis of methane. The majority of this returns to the surface, but some become trapped in______ at the sea floor.

What is it called when chemical reactions transform organic materials to oil (2km) and temperature ranging from 60° to 120°C is known as?

An organic matter-bearing rock from which gas and oil are formed, what is it called?

This is often permeable, allowing fluids to migrate from the source rocks and facilitates oil/gas recovery/extraction.

There are 5 Major traps that consists of:

Over 30% of the global oil supply is located in the ______.

What method is extracted as oil turns into an oil reservoir?

These are areas that are underlain by one or more oil reserves.

The “________” is the cost-saving phenomenon for oil companies, determines the success of drilling operations and prevents the need of abandoning them. What is it called?
