Coal, Oil & Gas Hyrdocarbons

Fossil fuels, formed from ancient organic matter, include coal, oil, and natural gas. Coal originates from plants, while oil and gas come from aquatic organisms. These fuels are crucial for energy and manufacturing but pose environmental risks like global warming and acid rain. As finite resources, they necessitate a shift to renewable energy.

What is the primary difference in the formation of coal compared to oil and natural gas?

• Coal is formed mainly from trees and other plants.

• Coal is formed from marine organisms.

• Coal is formed from mineral deposits.

• Coal is formed from volcanic activity.

Which of the following is a common use of natural gas in households?

• Cooking and heating water

• Manufacturing plastics

• Fueling cars

• Generating electricity

What process is used to separate oil into useful fuels and chemicals?

• Filtration

• Fractional distillation

• Electrolysis

• Crystallization

Which gas is primarily responsible for global warming when fossil fuels are burned?

• Carbon dioxide

• Nitrogen

• Helium

• Oxygen

Why is it important to develop renewable energy sources?

• Fossil fuels are a renewable resource.

• Fossil fuels are environmentally friendly.

• Fossil fuels are infinite.

• Fossil fuels will eventually run out.
