Highlight any three causes of soil …

1. Water runoff and rainfall intensity:  This process begins when the raindrops break down the soil making it vulnerable to movement. The lighter soil aggregates like silt, fine sand, clay and organic matter are then easily carried away by the moving water.
2. The slope of the land:  The topography of the land may also be a cause of soil erosion. Steeper areas experience a higher intensity of runoff due to the increased speed. Even heavier particles can easily be carried away by the moving water. This reason why hilly areas do face a more violent erosion compared to a flat land.
3. Soil texture: The fineness and the structure of soil particles may also prompt the occurrence of an erosion. The fine and loose soil structures can be easily carried away more than the large and firm soil.
4.  Deforestation: When vegetation cover is destroyed, the land gets exposed to the agents of soil erosion. Trees act as barriers against many causes of soil erosion including raindrops and moving wind. Roots also serve in binding the soil together hence cannot be easily disintegrated and made available for the agents of erosion.
