Which of the following are natural environmental factors that affect air pollution?

The correct answer focuses on natural environmental factors, specifically topography, latitude, and longitude, which all play significant roles in influencing air pollution levels.

Topography refers to the physical features of a landscape, including mountains, valleys, and plains. These features can affect air movement and dispersion of pollutants. For instance, valleys may trap air pollutants due to temperature inversions, where warmer air traps cooler air at lower altitudes, thereby limiting the dispersal of pollutants.

Latitude and longitude impact climate and weather patterns, which are crucial in determining how pollutants behave in the atmosphere. For example, regions at different latitudes may experience varying levels of sunlight, temperature, and precipitation, all of which influence the formation and breakdown of air pollutants.

In contrast, the other options include factors that are either anthropogenic (human-made) or directly associated with societal growth and patterns rather than purely natural environmental influences. Population density and urbanization, as well as human activity, are driven by human actions and thus are not classified as natural factors. Weather, while it can be influenced by natural phenomena, is better categorized as a dynamic condition rather than an underlying environmental factor.

Understanding these natural influences helps in developing effective strategies for air quality management and pollution control that consider
