How does topography affect air pollution?
How does topography affect air pollution?
On hill tops and exposed areas, moderate wind will typically cause the pollutant to be dispersed (blown and spread out) but in low-lying areas like valleys, it is harder for the wind to penetrate, causing air pollutants to become trapped and levels of air pollution to rise.
How geographical and climatic conditions affect the local air pollution?
In urban areas, climate change is likely to influence outdoor air pollution levels because the generation and dispersion of air pollutants, such as ozone and particulate matter, depend in part on local patterns of temperature, wind, solar radiation and precipitation [4].
How does climate change affect air pollution?
Climate change might also affect human health by making our air less healthy to breathe. Higher temperatures lead to an increase in allergens and harmful air pollutants. Higher temperatures associated with climate change can also lead to an increase in ozone, a harmful air pollutant.
How do geographical conditions affect local air pollution?
Natural geographical features may also affect air pollution. For example, the proximity to water bodies affecting air flow in river valleys and oceans could be related to air pollution.
What type of geography is air pollution?
Air pollution is most common in large cities where emissions from many different sources are concentrated. Sometimes, mountains or tall buildings prevent air pollution from spreading out. This air pollution often appears as a cloud making the air murky.
What are the 5 main human sources of air pollution?
mobile sources – such as cars, buses, planes, trucks, and trains. stationary sources – such as power plants, oil refineries, industrial facilities, and factories. area sources – such as agricultural areas, cities, and wood burning fireplaces. natural sources – such as wind-blown dust, wildfires, and volcanoes.
What are the two main types of ocean pollution?
Pollutants are dumped into the ocean. This waste affects the daily life of fish and other marine creatures. Marine pollution is a growing problem in today’s world. Our ocean is being flooded with two main types of pollution: chemicals and trash.
How do humans pollute the oceans?
Chemical pollution Common man-made pollutants that reach the ocean include pesticides, herbicides, fertilizers, detergents, oil, industrial chemicals, and sewage. Many ocean pollutants are released into the environment far upstream from coastlines.
