Correct Answer: Correct answer is: (B) Deforestation.

Difficulty: Moderate

Common Mistakes: Students may confuse industrialization or road construction as the primary cause, overlooking the significant impact of deforestation on soil stability.

Explanations: Deforestation leads to soil erosion because trees and vegetation play a crucial role in preventing soil from being washed or blown away. Their roots bind the soil, and their canopies protect the soil from the direct impact of rain. When forests are cleared, the soil becomes more susceptible to erosion by wind and water.

Option A: Industrialization can contribute to soil erosion, but it is not the primary cause. Industrial activities often lead to pollution and land degradation, but deforestation has a more direct and significant impact on soil erosion.
Option B: Deforestation is the correct answer because it directly removes the protective vegetation that holds soil in place, leading to increased erosion.
Option C: Earthquakes can cause soil erosion, but they are not a consistent or primary cause. They are natural disasters that occur sporadically and do not have the same long-term impact as deforestation.
Option D: Road construction can contribute to soil erosion, but it is localized and not as widespread as the effects of deforestation. Roads can disrupt soil stability, but the removal of large areas of vegetation through deforestation has a more significant impact.
