Explanation
The government in Bangkok takes measures to prevent air pollution by featuring a subway line and an above ground sky train in 2004 and improving fuel quality. These actions aim to reduce the reliance on private vehicles and promote the use of public transportation, which can help decrease emissions. Additionally, improving fuel quality can lead to cleaner combustion and reduced pollution from vehicles.
8.
What are the causes of air pollution in London?
Correct Answer
A. People are burning more coal and an anticyclone blew all the smog
Explanation
The correct answer suggests that air pollution in London is caused by two factors: people burning more coal and an anticyclone blowing all the smog. Burning coal releases pollutants into the air, contributing to air pollution. An anticyclone is a weather phenomenon that can trap pollutants and prevent their dispersion, leading to the accumulation of smog in the area. Thus, the combination of increased coal burning and the presence of an anticyclone can explain the causes of air pollution in London.
9.
What measurements does the government in London take to prevent smog?
Correct Answer
C. Government decreed that emission of black smoke is illegal and residents and factories operators had to switch to smokeless fuels
Explanation
The government in London takes measures to prevent smog by decreeing that the emission of black smoke is illegal and requiring residents and factory operators to switch to smokeless fuels. This regulation aims to reduce the amount of pollutants released into the air, thereby improving air quality and preventing the formation of smog. By enforcing this decree, the government is taking proactive steps to address the issue of smog and protect the health and well-being of its citizens.
10.
What contributed to acid rain in Japan?
Correct Answer
B. Coal burning and emission of harmful chemical by factories
Explanation
Coal burning and emission of harmful chemicals by factories contributed to acid rain in Japan. This is because when coal is burned, it releases sulfur dioxide and nitrogen oxides which react with water vapor in the atmosphere to form sulfuric acid and nitric acid respectively. These acids then fall back to the earth's surface as acid rain. Additionally, factories emitting harmful chemicals further exacerbate the problem by releasing pollutants that contribute to the acidity of the rain.
11.
What can be classified as PRIMARY pollutants?
Correct Answer(s)
A. Sulfur dioxide
B. Carbon dioxide
C. Hydrogen fluoride
Explanation
Primary pollutants are substances that are directly emitted into the atmosphere from human activities or natural sources. They are harmful pollutants that can have direct adverse effects on human health and the environment. Sulfur dioxide, carbon dioxide, and hydrogen fluoride are all examples of primary pollutants. Sulfur dioxide is mainly emitted from burning fossil fuels, carbon dioxide is primarily released through the burning of fossil fuels and deforestation, and hydrogen fluoride is emitted from industrial processes such as aluminum production and glass manufacturing. These pollutants contribute to air pollution and can lead to respiratory issues, climate change, and damage to ecosystems.
