What physical feature traps air pollution in Mexico City Mexico?
Located in the crater of an extinct volcano, Mexico City is about 2,240 metres above sea level. The lower atmospheric oxygen levels at this altitude cause incomplete fuel combustion in engines and higher emissions of carbon monoxide and other compounds. Intense sunlight turns these into higher than normal smog levels.
What surrounds Mexico City that traps the air pollution over the city?
Mexico City sits in a high mountain valley, where the surrounding mountains can trap pollutants and prevent them from dispersing. The city is 7,350 feet (2,240 meters) above sea level.
How has Mexico City solved air pollution?
By installing renewable energy units like solar panels and solar heaters across the city in private and public buildings over five years, the city aims to slash carbon emissions by 2 million tons to improve air quality in Mexico City.
What physical feature traps pollutants above Mexico City?

What layer traps the pollutants in Mexico City?
inversion layer
Less oxygen at that altitude reduces the efficiency of vehicle engines, so they release more pollutants than they might elsewhere. Worse, warm air above the valley, called an “inversion layer,” seals in the pollution.
How does geography play a role in Mexico City’s air pollution problem?
Q. How does geography play a role in Mexico City’s air pollution problem? It’s surrounded by mountains which trap the air. It’s near the Atacama desert, which causes sandstorms.
Which physical feature helps trap a lot of the air pollution from the wind taking it away from Mexico City?

Is Mexico City air quality?
Throughout 2019, Mexico City’s registered air quality was between 12.1 and 35.4 µg/m³. The highest level recorded was in May when the figure jumped to 34 µg/m³. Looking back over previous years, it is not seen to change by a noticeable amount. In 2017 the reading was 20.4 µg/m³ followed by 19.7 µg/m³ in 2018.
What has caused air pollution?
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.
