Detailed explanation-1: -The correct answer is Afforestation. Afforestation is not a cause of soil erosion.
Detailed explanation-2: -Soil compaction, low organic matter, loss of soil structure, poor internal drainage, salinisation and soil acidity problems are other serious soil degradation conditions that can accelerate the soil erosion process.
Detailed explanation-3: -What Causes Erosion? Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.
Detailed explanation-4: -1) Sheet erosion by water; 2) Wind erosion; 3) Rill erosion – happens with heavy rains and usually creates smalls rills over hillsides; 4) Gully erosion – when water runoff removes soil along drainage lines. 5) Ephemeral erosion that occurs in natural depressions. 21-Jul-2020
