A boy wears a face mask and sits next to an air purifier. He looks out his window at a smog-clouded city in China.

How does China's geography contribute to the environmental hazard shown?

(1 point)

Rivers carry toxins from factories downstream to populated areas throughout the country.


Wind carries air pollution to dense urban centers and smog settles in heavily populated lowlands.


Plate tectonic activity undermines stability in industrial areas, making them vulnerable to leaks.


Runoff from farms and plants causes ground pollution that contributes to acid rain in regions with heavy precipitation.

Answer 1

Wind carries air pollution to dense urban centers and smog settles in heavily populated lowlands.

China’s industrial emissions and prevailing winds (plus temperature inversions in basins/lowlands like the North China Plain and Sichuan Basin) trap pollutants, creating persistent smog.
