Why can soil erosion increase due to deforestation?
Answer and explanation
Correct answer: Tree roots bind the soil; when trees are cut, loose soil can be washed away
Tree roots hold soil particles together, while vegetation reduces the direct impact of raindrops and flowing water. When forests are cleared, the exposed soil becomes loose and can be carried away easily by rainwater or wind. Option B concerns an unsupported change in soil minerals, not the cause of erosion. Exam tip: remember that roots bind soil, so deforestation increases soil erosion.
