Which of the following describes a potential consequence of soil erosion?

Soil erosion can significantly compromise the structural integrity of foundations. When soil is eroded from around a building or infrastructure, it can lead to a reduction in support for the structures above. This loss of soil can result in uneven settling, which may cause cracks in walls, shifted foundations, or even complete failure in severe cases. The erosion process often also exposes the underlying layers of soil or rock, which may be less stable or have different properties compared to the eroded topsoil. As a result, it is critical to understand the impacts of soil erosion not just on the land but also on the safety and durability of constructed elements.

The other options describe outcomes that are generally not associated with soil erosion. For example, while some might mistakenly think erosion improves soil quality, it typically depletes the topsoil, which is vital for nutrient retention. Similarly, erosion is more likely to decrease agricultural yield rather than increase it, as the loss of nutrient-rich soil directly affects crop productivity. Lastly, soil erosion typically diminishes groundwater recharge as it can lead to increased runoff, reducing the amount of water that is able to percolate into the ground and replenish aquifers.
