18. What is the main source of air pollution in Kenyan cities?
The main source of air pollution in Kenyan cities is vehicle emissions from cars and trucks, which release harmful pollutants into the air.
19. Which of the following is NOT a greenhouse gas that contributes to air pollution?
Oxygen is not a greenhouse gas. The other options - carbon dioxide, methane, and nitrous oxide - are greenhouse gases that contribute to air pollution.
20. What is the harmful component in smog that can cause respiratory problems?
Sulfur dioxide is a harmful component in smog that can cause respiratory problems when inhaled in high concentrations.
21. Which human activity contributes to deforestation and increases air pollution?
Mining activities contribute to deforestation and air pollution by releasing pollutants into the air and destroying trees and vegetation.
22. What can individuals do to reduce air pollution in their daily lives?
Using public transportation can help reduce air pollution by decreasing the number of vehicles on the road emitting harmful gases into the atmosphere.
23. Which of the following is a renewable source of energy that can help reduce air pollution?
Wind power is a renewable source of energy that can help reduce air pollution by producing electricity without burning fossil fuels and releasing harmful emissions.
24. What is the main health concern associated with air pollution?
Air pollution can cause respiratory problems such as asthma, bronchitis, and other lung diseases due to inhaling polluted air.
25. Which type of pollution is caused by the burning of fossil fuels?
The burning of fossil fuels releases pollutants into the air, causing air pollution that can harm human health and the environment.
26. What can governments do to reduce air pollution in cities?
Governments can help reduce air pollution by planting more trees, which absorb carbon dioxide and other pollutants from the air.
27. What is the effect of air pollution on the ozone layer?
Air pollution can deplete the ozone layer by releasing ozone-depleting substances such as chlorofluorocarbons (CFCs), which thin the ozone layer and allow harmful UV radiation to reach the Earth's surface.
28. Which of the following is a major source of air pollution in Nairobi?
Motor vehicles release harmful pollutants into the air through their exhaust pipes.
29. What is the main cause of air pollution from industries?
Industries burn fossil fuels like coal and oil, which release harmful gases into the air causing pollution.
30. Which of the following is a greenhouse gas that contributes to air pollution?
Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, leading to global warming and air pollution.
31. What can individuals do to reduce air pollution in their community?
Planting trees helps to absorb pollutants from the air and reduce air pollution in the community.
32. Which of the following activities does not contribute to air pollution?
Using public transportation reduces the number of cars on the road and helps in decreasing air pollution.
33. What is the main health effect of long-term exposure to air pollution?
Long-term exposure to air pollution can lead to respiratory diseases such as asthma and bronchitis among other health issues.
34. Which of the following is a human activity that leads to deforestation and air pollution?
Logging for timber leads to deforestation which in turn contributes to air pollution and loss of biodiversity.
35. What is the role of the ozone layer in protecting the Earth from air pollution?
The ozone layer absorbs harmful ultraviolet (UV) radiation from the sun and protects the Earth from the harmful effects of air pollution.
36. Which of the following pollutants causes acid rain?
Sulfur dioxide reacts with water vapor in the atmosphere to form sulfuric acid, leading to acid rain.
37. How does air pollution affect wildlife in Kenya?
Air pollution can lead to respiratory problems in wildlife and disrupt their habitats, affecting their health and survival.
