How does increase in temperature affect air pollution Mcq?

9. How does increase in temperature affect air pollution? Explanation: Generally, air pollution increases with increase in temperature because it leads to increase in ground level ozone, nitrogen dioxide concentrations increase since higher temperature favours the oxidation of nitrogen monoxide.

How does temperature impact air quality?

Air quality decreases during times of hot temperatures because the heat and sunlight essentially cook the air along with all the chemical compounds lingering within it. This chemical soup combines with the nitrogen oxide emissions present in the air, creating a “ smog” of ground-level ozone gas.

What is the effect of air pollution on plants Mcq?

Explanation: Air pollution has an adverse effect on crops and plants. They reduce the growth and yield of crops by increasing the rate of premature plant death. This decreases the overall productivity of an ecosystem. 6.

Does pollution Increase temperature?

“Burning fossil fuels releases gases and chemicals into the air.” And in an especially destructive feedback loop, air pollution not only contributes to climate change but is also exacerbated by it. “Air pollution in the form of carbon dioxide and methane raises the earth's temperature,” Walke says.

How does increase in temperature affect air pollution?

Heat waves often lead to poor air quality. The extreme heat and stagnant air during a heat wave increases the amount of ozone pollution and particulate pollution. Drought conditions can also occur during a heat wave, meaning that soils are very dry. During a drought, forest fires are more common.

Important MCQs On Air Pollution

How does air temperature affect air pressure?

Air pressure can also change with the temperature. Warm air rises resulting in lower pressure. On the other hand, cold air will sink making the air pressure higher. This is where the terms “low pressure” and “high pressure” come from.

What factors affect air pollution?

What is air pollution causes and effects?

Air pollution has resulted in several respiratory disorders and heart diseases among humans. The cases of lung cancer have increased in the last few decades. Children living near polluted areas are more prone to pneumonia and asthma. Many people die every year due to the direct or indirect effects of air pollution.

How does air pollution affect 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).

Why does air pollution increase during winter short answer?

Cold air is denser and moves slower than warm air. This density means that cold air traps the pollution but also doesn't whisk it away. Air pollution in winter remains in place for much longer and therefore is breathed in at a higher rate than during the summer.

What are air pollutants Mcq?

Carbon monoxide, Sulphur dioxide, Nitrogen dioxide, Ozone, and Particulate Matter are the major air pollutants.

Which one of the following is the main cause of air pollution Mcq?

Answer: (c) Both incinerators and emissions from vehicles.

How does temperature affect primary and secondary pollution?

When weather is hot, primary sources of pollutants tend to increase. Sun and heat can transform primary air pollutants into secondary pollutant that can be even more toxic. Heatwaves often come with high atmospheric pressure, that creates a stagnant layer of air above ground level.

How does temperature affect particulate matter?

The study results indicated that PM emissions increased exponentially as temperature decreased. In general, PM emissions doubled for every 20 degrees F drop in ambient temperature, with these increases independent of vehicle model year.

What are the effects of air pollution Class 8?

What are the effects of pollution?

Exposure to high levels of air pollution can cause a variety of adverse health outcomes. It increases the risk of respiratory infections, heart disease and lung cancer. Both short and long term exposure to air pollutants have been associated with health impacts. More severe impacts affect people who are already ill.

What are the 6 effects of air pollution?

Air pollution is considered as the major environmental risk factor in the incidence and progression of some diseases such as asthma, lung cancer, ventricular hypertrophy, Alzheimer's and Parkinson's diseases, psychological complications, autism, retinopathy, fetal growth, and low birth weight.

What are the 3 main causes of air pollution?

What are the two main causes of air pollution?

What are the effects of air pollution essay?

It is the cause of many skins and respiratory disorder in human beings. Also, it causes heart disease too. Air pollution causes asthma, bronchitis, and many other diseases. Moreover, it increases the rate of aging of lungs, decreases lungs function, damage cells in the respiratory system.

How does temperature affect the level of smog in the city?

Temperature Heat increases the chemical conversion of emissions to ozone and particle pollution. Lower temperatures can enable gaseous emissions to convert into particles.

What are the causes of air pollution Brainly?

What are the effects of air pollution Wikipedia?

Air pollution can cause diseases, allergies, and even death to humans; it can also cause harm to other living organisms such as animals and food crops, and may damage the natural environment (for example, climate change, ozone depletion or habitat degradation) or built environment (for example, acid rain).

How does temperature affect density of air?

Air density and temperature are like opposite ends of a see-saw — lower temperatures leads to higher density, and higher temperatures to lower density. This is because warmer molecules of air move faster, creating an expansion effect that decreases air density.
