Which factor increases the chance of pollution travel?

The correct response highlights that the various conditions mentioned can contribute to the increased likelihood of pollution travel in an environment. Acidic soil conditions can lead to the mobility of heavy metals and other contaminants, making it easier for these pollutants to leach into groundwater or surface water.

When organic materials are lacking, the soil structure can become less stable, resulting in less effective filtration and binding of pollutants. This instability encourages the movement of contaminants through the soil profile. Additionally, deficiencies in essential nutrients like iron (Fe), magnesium (Mg), and calcium (Ca) can affect soil health and its ability to retain pollutants, thus promoting the migration of contaminants within the environment.

Together, these factors create a scenario where pollution can travel more freely, impacting water quality and soil health. Therefore, collectively, they contribute to an environment that is more susceptible to the movement of pollutants, supporting the choice that all the factors listed increase the chance of pollution travel.
