Fossil Fuels Test! MCQ Quiz!

1. Coal supplies over half the United States electricity.

True

False

Coal supplies over half of the United States' electricity because it is a widely available and relatively inexpensive source of energy. Coal-fired power plants are able to generate large amounts of electricity, making it a significant contributor to the country's energy mix. However, it is important to note that the use of coal for electricity generation has been declining in recent years due to concerns about its environmental impact and the increasing adoption of renewable energy sources.

2. Oil wells bring up crude oil, which is then refined into more useful products. Which of these is not made by refining crude oil.

Petrol

Diesel

Kerosene

Natural gas

Natural gas is not made by refining crude oil. Natural gas is a fossil fuel that is primarily composed of methane and is formed through the decomposition of organic matter over millions of years. It is typically found in underground reservoirs and is extracted through drilling wells specifically for natural gas. While crude oil can be refined to produce petrol, diesel, and kerosene, natural gas is a separate resource that is not derived from crude oil refining.

3. Natural gas is made of _____ which is made of carbon and hydrogen atoms.

Natural gas is primarily composed of methane, which is a molecule made up of carbon and hydrogen atoms. Methane is the simplest hydrocarbon and is the main component of natural gas. It is formed through the decomposition of organic matter in the absence of oxygen, such as in swamps, landfills, and the digestive systems of animals. Methane is a potent greenhouse gas and is also used as a fuel source for heating, cooking, and electricity generation.

4. Burning fossil fuels releases _____ into the atmosphere.

Burning fossil fuels, such as coal, oil, and natural gas, releases carbon dioxide into the atmosphere. This is because fossil fuels are made up of carbon, and when they are burned, the carbon combines with oxygen in the air to form carbon dioxide. Carbon dioxide is a greenhouse gas that contributes to global warming and climate change. Its release into the atmosphere is a major factor in the increase of greenhouse gas concentrations and the resulting impact on the Earth's climate.

7. Most of the world's oil is found in sedimentary rock that is older than 200 million years old.

True

False

it is younger than 200 million years.

Explanation

it is younger than 200 million years.

8. Match the following:

The greatest amount of oil is found in which country.

Most natural gas is produced by

Most Coal is produced by

Submit

9. 70% of our energy comes from fossil fuels.

True

False

It is around 90%

Explanation

It is around 90%

10. Which of these are part of the stages of coal formation?

Oxygen

Lignite

Graphite

Peat

Peat and lignite are part of the stages of coal formation. Peat is the earliest stage, formed from partially decomposed plant matter in waterlogged conditions. Lignite is the next stage, formed from the compaction and heating of peat over time. Graphite, on the other hand, is not part of the stages of coal formation. It is a different mineral formed under different geological conditions. Oxygen is also not part of the stages of coal formation, as it is a chemical element and not a stage in the formation process.
