Questions and Answers
- 1.
Which gas makes up the largest part of air?
- A.
Carbon dioxide
- B.
Oxygen
- C.
Nitrogen
- D.
Sulfur dioxide
Correct Answer
C. NitrogenExplanation
Nitrogen makes up the largest part of air. It constitutes about 78% of the Earth's atmosphere, making it the most abundant gas. Oxygen is the second most abundant gas in the atmosphere, followed by small amounts of other gases such as carbon dioxide and sulfur dioxide. However, nitrogen is the dominant gas and plays a crucial role in supporting life on Earth.Rate this question:

Which of the following substances is not an atmospheric pollutant?
- A.
Carbon monoxide
- B.
Helium
- C.
Oxides of nitrogen
- D.
Sulfur dioxide
Correct Answer
B. HeliumExplanation
Helium is not an atmospheric pollutant because it is a noble gas and does not react with other elements or compounds in the atmosphere. Unlike carbon monoxide, oxides of nitrogen, and sulfur dioxide, which are all harmful pollutants released from various sources such as vehicles and industrial processes, helium is inert and does not contribute to air pollution or pose any health risks.Rate this question:

Which of the following gases is not present in the air?
- A.
Carbon dioxide
- B.
Hydrogen
- C.
Nitrogen
- D.
Water vapour
Correct Answer
B. HydrogenExplanation
Hydrogen is not present in the air because it is the lightest and most buoyant gas, causing it to escape the Earth's atmosphere and dissipate into space. While carbon dioxide, nitrogen, and water vapor are all components of the Earth's atmosphere, hydrogen is not naturally found in significant quantities.Rate this question:

What is the approximate percentage of nitrogen in the air?
- A.
0.04%
- B.
20%
- C.
50%
- D.
79%
Correct Answer
D. 79%Explanation
The correct answer is 79%. Nitrogen makes up the majority of the Earth's atmosphere, with approximately 79% of the air being composed of this element. This high percentage of nitrogen is important for supporting life on Earth, as it is a crucial component of proteins and nucleic acids. It also plays a role in the nitrogen cycle, which is essential for the growth and development of plants and other organisms.Rate this question:

The percentage composition of rare gases in air is
- A.
1%
- B.
2%
- C.
3%
- D.
0.1%
Correct Answer
D. 0.1%Explanation
The correct answer is 0.1% because rare gases, such as helium, neon, argon, krypton, and xenon, make up a very small fraction of the Earth's atmosphere. These gases are present in trace amounts, with argon being the most abundant rare gas at approximately 0.93% of the atmosphere. Therefore, the percentage composition of rare gases in air is much lower than the other options provided.Rate this question:

- 6.
Over 90% of the air is made up of these two gases.
- A.
Oxygen and rare gases
- B.
Nitrogen and oxygen
- C.
Nitrogen and carbon dioxide
- D.
Oxygen and carbon dioxide
Correct Answer
B. Nitrogen and oxygenExplanation
The given question asks for the two gases that make up over 90% of the air. The correct answer is nitrogen and oxygen. This is because nitrogen makes up about 78% of the air, while oxygen makes up about 21%. Together, these two gases account for over 90% of the composition of the air.Rate this question:

The bar chart shows the amounts of pollution in the atmosphere produced by petrol-driven vehicles and from coal-burning power stations. Which source of pollution produces the most carbon monoxide?
Correct Answer
vehiclesExplanation
The bar chart shows the amounts of pollution in the atmosphere produced by petrol-driven vehicles and coal-burning power stations. Since the question asks for the source of pollution that produces the most carbon monoxide, we can compare the bar heights for carbon monoxide emissions from both sources. From the chart, it is evident that the bar representing vehicles is taller than the bar representing power stations, indicating that vehicles produce more carbon monoxide pollution.Rate this question:
- 8.
The bar chart shows the amounts of pollution in the atmosphere produced by petrol-driven vehicles and from coal-burning power stations. Which source of pollution produces the most sulfur dioxide?
Correct Answer
power stationsExplanation
The bar chart provides information about the levels of pollution caused by petrol-driven vehicles and coal-burning power stations. The question asks which source produces the most sulfur dioxide. Since the answer provided is "power stations," it suggests that the bar chart indicates that coal-burning power stations emit a higher amount of sulfur dioxide compared to petrol-driven vehicles.Rate this question:
- 9.
The bar chart shows the amounts of pollution in the atmosphere produced by petrol-driven vehicles and from coal-burning power stations. Which chemical element makes up the largest part of 'solid particles'?
Correct Answer
carbonExplanation
The bar chart compares the pollution levels in the atmosphere caused by petrol-driven vehicles and coal-burning power stations. The question asks for the chemical element that constitutes the largest portion of "solid particles." Since coal is predominantly composed of carbon, it is reasonable to infer that carbon would make up the largest part of the solid particles emitted from coal-burning power stations.Rate this question:
- 10.
The bar chart shows the amounts of pollution in the atmosphere produced by petrol-driven vehicles and from coal-burning power stations. Which pollutant is produced by petrol engines but not by power stations?
Correct Answer
leadExplanation
Petrol engines produce lead as a pollutant, while power stations do not. This is evident from the bar chart, which shows the amounts of pollution in the atmosphere produced by both sources. Lead is specifically associated with petrol-driven vehicles, making it the correct answer.Rate this question:
