Question

Quizplus · Accepted Answer

Urban areas heat up more rapidly than their surroundings, creating low pressure over urban areas. This low pressure causes air to rise, and as it cools, it can carry pollutants aloft. Eventually, this air can move out over the surrounding countryside and sink, potentially depositing the pollutants in those areas.
