What is the source of most air pollution?
The number one source of outdoor air pollution is the burning of fossil fuels, primarily by motor vehicles. However, manufacturing industries, mining, and coal- and gas-fired power stations are also responsible for polluting the atmosphere.
Which action is the primary cause of air pollution quizlet?
The main cause of air pollution is human activity.
What is a major source of air pollution created by humans?
Humans have come to rely on fossil fuels to power cars and planes, heat homes, and run factories. Doing these things pollutes the air with carbon dioxide. Other greenhouse gases emitted by natural and artificial sources also include methane, nitrous oxide, and fluorinated gases.
What are the major primary air pollutants and their sources?
The gaseous criteria air pollutants of primary concern in urban settings include sulfur dioxide, nitrogen dioxide, and carbon monoxide; these are emitted directly into the air from fossil fuels such as fuel oil, gasoline, and natural gas that are burned in power plants, automobiles, and other combustion sources.
What is the biggest single cause of air pollution quizlet?
The largest single air pollutant (in terms of the quantity emitted each year) is carbon monoxide. Between 1990 and 2009, emissions of the five major primary pollutants rose significantly. Photochemical reactions can lead to the formation of secondary pollutants.
Which of the following pollutants are considered primary pollutants?
Primary air pollutants: Pollutants that are formed and emitted directly from particular sources. Examples are particulates, carbon monoxide, nitrogen oxide, and sulfur oxide.
Which of the following is a natural source of air pollution quizlet?
Forest fires and volcanic eruptions will release smoke and ash into the air which will cause air pollution. They will release harmful gases like carbon dioxide and sulfur dioxide into the air. Similarly, dust storms and conifer trees also contribute to air pollution.
What is the difference between primary and secondary air pollutants quizlet?
What is the difference between primary and secondary pollutants? Primary pollutants are harmful substances emitted directly into the air. Secondary pollutants are formed when primary pollutants react with one another or with the basic components of air to form new harmful pollutants.
