Detailed explanation-1: -Water erosion is caused by two main forces-raindrop impact and flowing water. Raindrops can both destroy soil aggregates and transport soil small distances. Then, flowing water transports these detached particles down hill. The size of the particles transported increases with the kinetic energy of the water.
Detailed explanation-2: -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-3: -The correct answer is Water erosion.
Detailed explanation-4: -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.
