Exploring Coal and Petroleum

What is the primary process through which coal is formed?

• Carbonization

• Sedimentation

• Fossilization

• Metamorphism

Name the three main types of coal.

• Peat, Charcoal, Coke

• Graphite, Ash, Silt

• Sandstone, Limestone, Shale

• Anthracite, Bituminous, Lignite

What is anthracite coal known for?

• High moisture content and poor heating value.

• High carbon content and clean burning properties.

• Low carbon content and high emissions.

• Low sulfur content and high ash production.

How is lignite different from bituminous coal?

• Lignite is younger and has lower carbon content than bituminous coal.

• Lignite is a type of bituminous coal with similar properties.

• Lignite is primarily used for making steel, unlike bituminous coal.

• Lignite is older and has higher carbon content than bituminous coal.

List one major use of coal in industry.

• Electricity generation

• Cement production

• Cooking fuel

• Steel production

What is one way coal is used to generate electricity?

• Burning coal to produce steam that drives turbines.

• Using coal to create solar energy.

• Converting coal into natural gas for heating.

• Coal is used to power wind turbines.

How does coal mining impact the environment?

• Coal mining creates new habitats for wildlife.

• Coal mining has no effect on air quality.

• Coal mining helps reduce greenhouse gas emissions.

• Coal mining negatively affects the environment by causing habitat destruction, pollution, and contributing to climate change.

What are some pollutants released when coal is burned?

• Hydrogen sulfide

• Sulfur dioxide, nitrogen oxides, carbon monoxide, particulate matter, heavy metals (e.g., mercury, arsenic)

• Ozone

• Carbon dioxide

What is petroleum primarily composed of?

• Hydrocarbons

• Water

• Nitrogen

• Carbon Dioxide

Describe the refining process of petroleum.

• The refining process includes only the combustion of crude oil.

• Petroleum refining is solely about producing electricity.

• The refining process of petroleum only involves extraction and storage.

• The refining process of petroleum involves distillation, cracking, reforming, and treating to produce various fuel and chemical products.
