Question 1:

Which of the following is a fossil fuel?

A) Solar power
B) Wind energy
C) Natural gas
D) Hydroelectric power

Show Answer

Explanation: The correct answer is C) Natural gas. Natural gas is a fossil fuel formed from the remains of ancient plants and animals buried and subjected to high pressure and heat over millions of years. It is composed mainly of methane and is commonly used as a source of energy for heating, cooking, and electricity generation.

Question 2:

Which of the following statements about fossil fuels is true?

A) Fossil fuels are unlimited and will never run out
B) Fossil fuels have no impact on the environment
C) Fossil fuels are non-renewable and contribute to climate change
D) Fossil fuels are only found in remote areas of the world

Show Answer

Explanation: The correct answer is C) Fossil fuels are non-renewable and contribute to climate change. Fossil fuels, including coal, oil, and natural gas, are finite resources that took millions of years to form. Their extraction and combustion release greenhouse gases, contributing to climate change and air pollution. The combustion of fossil fuels is a significant source of carbon dioxide emissions, a major driver of global warming.

Question 3:

Which of the following is the most widely used fossil fuel for electricity generation?

A) Coal
B) Oil
C) Natural gas
D) Uranium

Show Answer

Explanation: The correct answer is A) Coal. Coal has been a historically dominant fossil fuel for electricity generation due to its abundance and relatively low cost. However, its use has been declining in many regions due to environmental concerns and the transition towards cleaner energy sources.

Question 4:

Which of the following is a major environmental impact associated with fossil fuel use?

A) Reduced greenhouse gas emissions
B) Preservation of biodiversity
C) Acid rain formation
D) Enhanced soil fertility

Show Answer

Explanation: The correct answer is C) Acid rain formation. Fossil fuel combustion releases sulfur dioxide and nitrogen oxides, which can react with atmospheric moisture to form sulfuric acid and nitric acid. These acids can then fall to the Earth's surface as acid rain, which has detrimental effects on ecosystems, soil, water bodies, and human-made structures.

Question 5:

What are the primary uses of fossil fuels?

A) Powering renewable energy technologies
B) Generating electricity and heat
C) Producing biodegradable materials
D) Supporting sustainable transportation systems

Show Answer

Explanation: The correct answer is B) Generating electricity and heat. Fossil fuels are widely used for electricity generation and heat production in power plants, industries, and households. They are also used as fuel for transportation, manufacturing processes, and the production of various goods and materials. However, their extensive use has raised concerns about environmental pollution and climate change.
