What are the causes and effects of smog?

The main sources of these precursors are pollutants released directly into the air by gasoline and diesel-run vehicles, industrial plants and activities, and heating due to human activities. Smog is often caused by heavy traffic, high temperatures, sunshine, and calm winds.

What causes industrial smog?

Industrial smog typically exists in urban areas where factories burn fossil fuels such as coal, which creates smoke and sulfur dioxide that mix with fog droplets to create a thick blanket of haze close to the ground.

What causes smog quizlet?

What causes smog and acid rain? London-type smog is caused by soot left in the air from burning coal. Photochemical smog is caused by nitrogen oxides combing with sunlight and other pollutants. Acid rain is caused by sulfur oxides and nitrogen oxides combining with water.

What type of reaction creates smog?

Photochemical smog is a type of air pollution due to the reaction of solar radiation with airborne pollutant mixtures of nitrogen oxides (NOx) and volatile organic compounds (hydrocarbons). Smog is a byproduct of modern industrialization.

What is the example of smog?

Smog is a mix of fog and smoke, or a layer of polluted air. An example of smog is a low-lying yellow or brown layer of air. A form of air pollution produced by the photochemical reaction of sunlight with hydrocarbons and nitrogen oxides that have been released into the atmosphere, especially by automotive emissions.

What are 5 causes of pollution?

We have listed 10 common air pollution causes along with the effects that have serious implication on your health on a daily basis.

  • The Burning of Fossil Fuels.
  • Industrial Emission.
  • Indoor Air Pollution.
  • Wildfires.
  • Microbial Decaying Process.
  • Transportation.
  • Open Burning of Garbage Waste.
  • Construction and Demolition.

What is the biggest cause of pollution?

Burning Fossil Fuels The biggest contributors of air pollution are from industry sources and power plants to generate power, as well as fossil fuel motor vehicles. The continuous burning of fossil fuels releases air pollutants, emissions and chemicals into the air and atmosphere.

What causes smog and acid rain?

Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.

What is smog quizlet?

-Smog: a poisonous mixture of smoke, aire, and other pollutants. -need: emissions, warmth/sunlight, and no air movement. – industrial and photochemical.

What gases cause photochemical smog?

What is photochemical smog? Photochemical smog is a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities.

Which of the following pollutants are responsible for the cause of smog?

2. Which of the following pollutants are responsible for the cause of SMOG? Sol: (c) Both incinerators and emissions from vehicles.
