The causes of soil erosion are:

1. Deforestation: The roots of the trees hold the soil together. So indiscriminate felling of the trees leads to soil erosion by running water and wind.
2. Floods and torrential rains: Floods and rains result in soil erosion especially when the land is devoid of any trees or vegetation cover.
3. Overgrazing of land: Grazing of animals may lead to the removal of grass cover, which may result in soil erosion.
