What is smog combination of?
Originally the term ‘smog’ meant a combination of smoke and fog, but it has recently come to refer to a combination of fine particulate matter and ground level ozone. Smog can also contain other harmful components such as nitrogen oxides, volatile organic compounds, sulphur dioxide and carbon monoxide.
What does the term smog refers to?
Smog is a common form of air pollution found mainly in urban areas and large population centers. The term refers to any type of atmospheric pollution—regardless of source, composition, or concentration—that creates a significant reduction in atmospheric visibility.
What is the combination of smog and fog called?
a mixture of smoke and fog is called as Smog. Smog is a mixture of air pollutants like nitrogen oxides and volatile organic compounds that combine with sunlight to form ozone.
What is the combination of 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. It tends to occur more often in summer, because that is when we have the most sunlight.
What is smog 1 point a combination of fire and water a combination of smoke and fog a combination of water and smoke a combination of air and water?
Some communities have “burn days” when residents can burn waste such as leaves in their yard. These limits on chemicals released into the air reduce the amount of smog. Therefore, smog is a combination of smoke and fog, which is option B.
What is smog short answer?
Smog is air pollution that reduces visibility. The term “smog” was first used in the early 1900s to describe a mix of smoke and fog. The smoke usually came from burning coal. Smog was common in industrial areas, and remains a familiar sight in cities today. Today, most of the smog we see is photochemical smog.
What is sulfurous smog?
Sulfurous smog, which is also called “London smog,” results from a high concentration of sulfur oxides in the air and is caused by the use of sulfur-bearing fossil fuels, particularly coal. This type of smog is aggravated by dampness and a high concentration of suspended particulate matter in the air.
Why is it called Los Angeles smog?
Photochemical smog, which is also known as “Los Angeles smog,” occurs most prominently in urban areas that have large numbers of automobiles. It requires neither smoke nor fog. This type of smog has its origin in the nitrogen oxides and hydrocarbon vapours emitted by automobiles…
How is smog formed Class 9?
Answer: The suspended particles like unburnt carbon particles and hydrocarbons mix with smoke and fog in the atmosphere, especially in the cold weather to form smog which results in a lowered visibility.
Which air pollutant combines with the Haemoglobin of our blood Class 8?
Carbon monoxide combines with the haemoglobin of our blood.
What are some facts about smog?
Smog is a type of air pollutant; the word “smog” is a combination of smoke and fog. Classic smog results from large amounts of coal burning in an area and is caused by a mixture of smoke and sulfur dioxide. It is a big problem today in Beijing, and in many other cities.
How bad is the smog?
Smog is a serious problem in many cities and continues to harm human health. Ground-level ozone, sulphur dioxide, nitrogen dioxide and carbon monoxide are especially harmful for senior citizens, children, and people with heart and lung conditions such as emphysema, bronchitis, and asthma.
What is the main cause of smog?
Main Causes of Smog. One of the major causes of smog is coal, which discharges high concentrations of sulfur oxides in the atmosphere. Vehicle and industrial emission is another cause, as combustion of fossil fuel in the locomotive machines contributes highly to smog formation.
What are the causes and effects of smog?
Smog causes health problems affecting the respiratory system. There is an increase in Asthma, Emphysema, Chronic Bronchitis, Chronic Obstructive Pulmonary Disease (COPD)and lung cancer. It causes eye irritation. It breaks down natural immunity of the body, and makes it prone to colds and lung infections.
