Active Reading What Causes Air Pollution

What causes active reading air pollution?

Burning fossil fuels releases huge quantities of sulfur dioxide and nitrogen oxide into the air. Power plants that produce electricity emit at least two-thirds of all sulfur dioxide and more than one-third of all nitrogen oxides that pollute the air.

What causes polluted air?

Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust factories dust pollen mold spores volcanoes and wildfires. The solid and liquid particles suspended in our air are called aerosols.

What do most industries and power plants use for energy?

What do most industries and power plants use for energy? Many industries and power plants that generate our electricity must burn fuel to get the energy they need. They usually burn fossil fuels. Burning fossil fuels releases huge quantities of sulfur dioxide and nitrogen oxide into the air.

What is acid rain Answer Key?

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere where they mix and react with water oxygen and other chemicals to form more acidic pollutants known as acid rain.

Which of the following air pollutants is not a primary pollutant?

Which of these is NOT a primary pollutant? Explanation: Ozone is not a primary pollutant since it is formed by the photo-chemical reaction of oxygen with the UV rays and not directly discharged into the atmosphere by a source.

Where do most pollutants end up?

Eighty percent of pollution to the marine environment comes from the land. One of the biggest sources is called nonpoint source pollution which occurs as a result of runoff.

What is air pollution causes and effects?

Air pollution is known to cause irritation in the eyes lungs nose and throat. It creates respiratory problems and exacerbates existing conditions such as asthma and emphysema. When continually exposed to air pollution humans become at higher risk for cardiovascular disease.

What is air pollution and what are the main causes of air pollution?

Air pollution is a mixture of solid particles and gases in the air. Car emissions chemicals from factories dust pollen and mold spores may be suspended as particles. Ozone a gas is a major part of air pollution in cities. When ozone forms air pollution it’s also called smog.

What are the causes and effects of pollution?

There are many causes of pollution including chemical pollution into bodies of water and soil through improper disposal practices and agricultural activities and noise and light pollution created by cities and urbanization as a result of population growth.

What type of power generation can cause air pollution?

Coal produces more pollution than any other energy source. While coal produces just 44% of U.S. electricity it accounts for 80% of power plant carbon emissions. Burning coal leads to soot smog acid rain global warming and carbon emissions.

How do you think we can minimize the air pollution released by technology?

Ways to Reduce Air Pollution
  • Riding a bike or walking instead of driving.
  • Taking a bus or carpooling.
  • Buying a car that has greater fuel efficiency.
  • Turning off lights and appliances when they are not in use.
  • Using energy efficient light bulbs and appliances.
  • Buying fewer things that are manufactured using fossil fuels.

What is the relationship between air pollution and human population?

Emissions do increase as population increases but not as fast. As the population of a city increases the emissions also increase but the per capita emissions decrease. There are fewer tons of emissions per person as cities grow because cities are more efficient than living dispersed over a large area.

What produces smog?

Photochemical smog is produced when sunlight reacts with nitrogen oxides and at least one volatile organic compound (VOC) in the atmosphere. Nitrogen oxides come from car exhaust coal power plants and factory emissions. … When sunlight hits these chemicals they form airborne particles and ground-level ozone—or smog.

What are natural causes of acid rain?

Natural Sources

The major natural causal agent for acid rain is volcanic emissions. Volcanoes emit acid-producing gases to create higher than normal amounts of acid rain or any other form of precipitation such as fog and snow to an extent of affecting vegetation cover and health of residents within the surrounding.

Why do pollutants spread easily in air?

This is mainly influenced by wind and temperatures. Air pollutants can be transported by wind causing a pollution to spread widely. Rain can remove pollutants from air causing soil and water pollution. Sunlight can aid the convertion of air pollutants to different substances.

Does wind remove pollutants from the air?

Air quality is affected by natural processes. Wind can move pollutants from their source to far-away locations. Precipitation can remove pollutants from the atmosphere. … A network of air quality monitors on the ground measures local concentrations of pollutants to provide more detailed forecasts of air quality.

How does air pollution affect the environment?

Air pollution can damage crops and trees in a variety of ways. Ground-level ozone can lead to reductions in agricultural crop and commercial forest yields reduced growth and survivability of tree seedlings and increased plant susceptibility to disease pests and other environmental stresses (such as harsh weather).
