How does the location of Los Angeles make it more susceptible to pollution?

• Its tropical location causes high temperatures, which increases air pollution.

• Its location in a bowl formed by mountains causes air pollution to get trapped.

• Its location on a large, flat plain exposes it to the wind, which carries air pollution.

• Its coastal location exposes it to pollution from the sea.

This primary pollutant creates a reddish brown gas creating photochemical smog and tropospheric ozone.

• sulfuric acid

• VOC

• nitrogen dioxide

• particulate matter

This atmospheric compound is critical to the planet in its protection against UV radiation, but when found close to the ground is part of photochemical smog that can cause serious health problems.

• particulate matter

• carbon monoxide

• stratospheric ozone

• tropospheric ozone

Which product of incomplete combustion gives photochemical smog its yellowish color?

• PANs

• Ozone

• VOCs

• Nitrous oxide
